BIS Establishes Six Indian Standards in 2026: What Manufacturers Need to Know Before the Old Standards Are Withdrawn

The Bureau of Indian Standards (BIS) has brought six Indian Standards into effect across a mix of industries, including steel testing, household and similar electrical appliances, iron ore processing, aviation components, mining equipment and conveyor belts.

The notification is dated 1 September 2026 and has been issued under Rule 15(1) of the Bureau of Indian Standards Rules, 2018. The Schedule shows 28 August 2026 as the date on which all six standards were established. 

Five of these standards replace older editions. Those older editions have not been withdrawn immediately. BIS has allowed them to remain in force alongside the new standards until 28 February 2027. The only exception is IS 228 (Part 37):2026 / ISO 10280:2025, where the Gazette shows “NA” against both the earlier standard and withdrawal date. 

For businesses, the practical work is not simply to note that a standard number has changed. Manufacturers, laboratories and technical teams need to identify whether an older edition is still being used in test methods, specifications, quality records, purchase documents or other technical material.

There is another distinction that matters here. This notification establishes and revises Indian Standards. It should not automatically be read as an order making BIS certification compulsory for every product mentioned in the Schedule.

BIS Notification at a Glance

BIS states that the standards shown in the second column of the Schedule were established on the dates shown against them. Where an older standard appears in the fourth column, that earlier standard remains in force concurrently until its withdrawal date in the fifth column. 

What Has Actually Changed Under the BIS Notification?

The notification does not create one common rule for six similar products. Instead, it deals with six separate technical standards.

There are three parts to the change.

Six Standards Have Been Established

Every standard included in the Schedule carries 28 August 2026 as its establishment date.

Five Older Standards Have a Defined Withdrawal Date

For five entries, BIS has identified the earlier edition and fixed 28 February 2027 as its withdrawal date.

This creates a period in which both the newer standard and the listed older standard remain in force.

One Standard Has No Previous Edition Listed for Withdrawal

For IS 228 (Part 37):2026 / ISO 10280:2025, the Schedule records “NA” in both the previous-standard and withdrawal-date columns. 

That difference should be reflected correctly in any compliance article or internal transition plan.

Six Indian Standards Established by BIS in 2026

The Gazette sets out these six entries together with their establishment dates, revision status and, where applicable, the standards they replace. 

Standard-Wise Analysis of the BIS Notification

IS 228 (Part 37):2026 / ISO 10280:2025- Titanium Content in Steel

The first entry concerns Methods for Chemical Analysis of Steels Part 37 Determination of Titanium Content Diantipyrylmethane Spectrophotometric Method.

Put simply, this standard relates to a method used to determine titanium content during the chemical analysis of steel.

It was established on 28 August 2026.

What makes this entry different from the other five is that BIS has not listed an older Indian Standard for withdrawal. The Schedule records:

• Earlier standard: NA 
• Withdrawal date: NA 

This may be relevant to steel producers, metallurgical laboratories and businesses whose quality-control or testing documents refer to methods for determining titanium content.

The notification itself does not provide the detailed analytical procedure. It does not specify sample preparation, instrument settings, acceptance criteria or test calculations. Those details have to be checked from the full Indian Standard.

IS 302 (Part 2/Sec 24):2026- Refrigerating Appliances, Ice-Cream Appliances and Ice-Makers

The second standard is particularly relevant to the electrical-appliance sector.

IS 302 (Part 2/Sec 24):2026 covers particular safety requirements for:

• refrigerating appliances 
• ice-cream appliances and 
• ice-makers. 

The Gazette identifies it as the First Revision and associates it with IEC 60335-2-24:2025, MOD. 

The earlier standard is:

IS 302-2-24:1994

Its scheduled withdrawal date is:

28 February 2027. 

Manufacturers using the 1994 standard in product files, engineering documents, test instructions or supplier specifications should therefore review those references.

The Gazette does not reproduce the actual technical changes made between the 1994 and 2026 editions. Those differences should be checked from the full revised standard before changing designs, test methods or compliance documents.

What Does “MOD” Mean Here?

The notification itself uses the notation “IEC 60335-2-24:2025, MOD” but does not explain it.

In standards terminology, “MOD” is generally used for a modified adoption of an international standard. That means businesses should not assume that the Indian Standard is word-for-word identical to the IEC document.

The exact Indian modifications can only be confirmed by reviewing the standard itself.

IS 8625:2026- Crushing Strength of Iron Ore Pellets

IS 8625:2026 deals with the method used for determining the crushing strength of iron ore pellets.

BIS identifies it as the Second Revision.

The earlier edition is:

IS 8625-1986

It is scheduled to be withdrawn on 28 February 2027. 

Businesses most likely to look at this change include:

• iron ore pellet manufacturers 
• mineral-processing units 
• testing laboratories 
• plant quality teams 
• procurement teams using the standard in specifications. 

If a testing SOP or quality document still cites the 1986 edition, the organisation should identify what has changed in the 2026 version before updating the procedure.

The Gazette does not state crushing-strength limits, sample quantities, test apparatus, or pass/fail criteria. Those technical points should not be inferred from the notification alone.

IS 9748:2026- Metallic Slide Fasteners for Aviation Purposes

IS 9748:2026 is the revised specification for metallic slide fasteners used for aviation purposes.

It is the First Revision of:

IS 9748-1981

The older edition will remain listed until 28 February 2027, when it is scheduled for withdrawal. 

The change may be relevant to:

• aviation component manufacturers 
• component suppliers 
• procurement teams 
• technical buyers 
• quality-control functions. 

Businesses should check whether the 1981 edition is still mentioned in drawings, purchase specifications or vendor requirements.

The BIS notification does not create a new aviation approval process in the text of this Gazette. Any sector-specific approval or certification requirement would need to be examined separately.

IS 10970:2026- Keps for Mine Cages

The fifth entry is IS 10970:2026 – Keps for Mine Cages Specification.

It is the First Revision of:

IS 10970-1984

The older edition is scheduled for withdrawal on 28 February 2027. 

This standard may matter to mine-equipment manufacturers, suppliers, procurement teams and businesses using equipment covered by the specification.

Where the older 1984 edition appears in technical files or procurement documents, those references should be reviewed.

Nothing in this particular notification should be used to invent a new mine-safety certification process. The notification deals with the standard and its withdrawal schedule.

IS 16384:2026 / ISO 21181:2025- Light Conveyor Belts

The final entry covers Light Conveyor Belts Determination of the Relaxed Elastic Modulus.

The new reference is:

IS 16384:2026 / ISO 21181:2025

It is the First Revision.

The previous reference was:

IS 16384:2017 / ISO 21181:2013

The earlier edition is scheduled for withdrawal on 28 February 2027. 

For conveyor-belt manufacturers and laboratories, the obvious review area is any test or product documentation that still refers to the 2017 edition.

The Gazette itself does not explain how relaxed elastic modulus is to be measured or calculated. Those technical requirements belong to the complete standard.

Which Older Indian Standards Will Be Withdrawn?

The following five standards have a common withdrawal date of 28 February 2027:

The Gazette does not list an earlier standard against IS 228 (Part 37):2026, so there is no withdrawal date shown for that entry. 

What Does Concurrent Validity Mean Until 28 February 2027?

BIS has not withdrawn the five older standards immediately.

The notification says that where an earlier standard is listed, it will remain in force concurrently until the withdrawal date shown in the Schedule. 

In practical terms, the position is:

• the 2026 standard has already been established 
• the previous edition continues during the overlap period 
• the previous edition is scheduled for withdrawal on 28 February 2027. 

However, businesses should be careful with one point.

Concurrent validity in this Gazette does not automatically mean that an organisation can freely choose either edition for every BIS certification, contractual or statutory purpose.

A separate:

• Quality Control Order 
• certification scheme 
• purchase specification 
• customer requirement 
• tender condition or 
• sector regulation 

may determine which version needs to be followed in a particular case.

That issue should be checked before relying on the overlap period.

Why Is There a Transition Period?

The Gazette does not expressly state why BIS has selected 28 February 2027 as the withdrawal date. It is therefore better not to attribute an official policy reason that the notification does not give. From an operational point of view, however, the overlap does give businesses time to find and review references to the older standards.

That review can cover:

• technical specifications 
• testing SOPs 
• laboratory reports 
• quality manuals 
• engineering drawings 
• procurement files 
• vendor specifications 
• customer requirements 
• tenders and contracts. 

These are sensible transition steps, but they should not be described as new statutory duties created by this Gazette.

Key Dates Businesses Should Keep on Their Compliance Calendar

The notification date and the date of establishment are not the same. That distinction matters when a business is updating its internal compliance records. 

Which Industries Need to Pay Attention?

The notification reaches several unrelated sectors. The level of impact will depend on whether a business actually uses the relevant standard.

Steel Manufacturers and Metallurgical Laboratories

Relevant standard: IS 228 (Part 37):2026 / ISO 10280:2025

The main area to check is chemical testing documentation dealing with titanium content in steel.

Technical teams may need to see whether an existing method, laboratory instruction or customer specification should now refer to the newly established standard.

Refrigerating Appliance and Ice-Maker Manufacturers

Relevant standard: IS 302 (Part 2/Sec 24):2026

Businesses dealing with refrigerators, ice-cream appliances and ice-makers should check references to IS 302-2-24:1994.

Product engineering, quality and compliance teams are likely to be the first functions that need to study the revised edition.

Iron Ore Pellet Producers

Relevant standard: IS 8625:2026

The revision is particularly relevant where crushing-strength testing forms part of a quality-control or contractual testing arrangement.

Companies should locate any remaining references to IS 8625-1986 and check the revised method before replacing existing procedures.

Aviation Component Manufacturers and Suppliers

Relevant standard: IS 9748:2026

Businesses manufacturing or sourcing metallic slide fasteners for aviation use should review product specifications and procurement documentation that still cites the 1981 edition.

Mining Equipment Businesses

Relevant standard: IS 10970:2026

Manufacturers, suppliers and users of relevant mine-cage equipment should check whether IS 10970-1984 appears in technical specifications or purchasing documents.

Conveyor Belt Manufacturers and Testing Functions

Relevant standard: IS 16384:2026 / ISO 21181:2025

Companies using the 2017 edition for light conveyor belt testing should review the newer standard and decide where internal documents need technical updates.

Stakeholder-Wise Impact of the BIS Standards Update

The table reflects practical business areas that may need review. It should not be read as a statement that the Gazette imposes every one of these activities as a statutory obligation.

Does This Notification Make BIS Certification Mandatory?

This Gazette notification does not, by itself, create one general mandatory BIS certification requirement for all six standards.

That distinction is easy to miss.

An Indian Standard tells businesses what technical standard has been established. A separate legal instrument may be needed before compliance with that standard becomes compulsory for a particular product.

For example, mandatory product compliance may depend on:

• an applicable Quality Control Order 
• a compulsory BIS certification requirement 
• another product-specific regulation 
• a licensing condition or 
• a separate statutory direction. 

This is why a business should not start a BIS application simply because it sees its product or technical area in a standards notification.

The first task is to check the regulatory applicability.

Indian Standard, BIS Certification and QCO: What Is the Difference?

This difference is especially relevant for manufacturers looking for BIS certification services. Before an application is prepared, the business should first confirm whether certification is actually required for that product.

Does the Notification Create a New BIS Licence or Registration Process?

No new application process is set out in this notification.

The Gazette does not specify:

• a BIS application form 
• registration portal 
• application documents 
• filing date 
• approval process 
• licence validity 
• renewal procedure. 

Businesses should also not treat 28 February 2027 as a common BIS registration deadline.

In this notification, the date is connected with the withdrawal of five older standards, not with a universal certification application.

Are Any New Fees Mentioned?

The notification does not specify:

• application fees 
• certification charges 
• testing fees 
• licence fees 
• renewal charges. 

Any commercial or regulatory cost will depend on what a particular business actually needs to do.

For one manufacturer, the work may be limited to reviewing technical documents. Another product may be covered by a separate mandatory certification regime that requires testing and an application.

Those situations should be assessed individually.

Does the Notification Introduce Any New Penalty?

The Gazette does not prescribe a separate penalty for the establishment or withdrawal of these standards.

It does not state a new:

• fine 
• imprisonment provision 
• seizure rule 
• licence-cancellation rule 
• import restriction 
• sales prohibition. 

Where another mandatory law or QCO applies, the consequences under that separate framework have to be checked independently.

International Standards Referred to in the Notification

The Schedule contains three direct international-standard references.

The previous IS 16384:2017 entry referred to ISO 21181:2013, while the new edition refers to the 2025 ISO standard. 

The Gazette does not provide enough detail to claim broader international equivalence beyond these references.

Impact on Manufacturers

For manufacturers, the most immediate issue is often document control.

A standard number may appear in many places inside a business, not just in the regulatory file.

For example, it may be written into:

• product specifications 
• engineering drawings 
• quality plans 
• test instructions 
• inspection formats 
• purchase specifications 
• supplier manuals 
• technical data sheets 
• customer documents. 

If the business uses one of the five earlier standards, those references should be located before the withdrawal date.

What Manufacturers Should Avoid

Manufacturers should not automatically:

• replace every old reference without studying the revised standard 
• assume all technical requirements remain unchanged 
• assume BIS certification has become mandatory 
• treat the withdrawal date as an application deadline 
• rely on an international standard without checking the Indian adoption. 

A controlled review is safer than a blanket document change.

Impact on Testing Laboratories and Quality-Control Teams

Laboratories can be affected even where there is no new certification filing.

If a laboratory currently tests against one of the older standards, it may need to examine:

• the revised test method 
• internal SOPs 
• test report formats 
• customer instructions 
• equipment references 
• quality documentation. 

Quality-control teams should also check whether acceptance or inspection documents refer to an old edition.

The Gazette itself does not say that a laboratory must change its accreditation scope. Accreditation requirements should be examined under the relevant accreditation framework rather than assumed from this notification.

Impact on Procurement and Tender Documents

Procurement documents are often overlooked during a standards transition.

An old standard can remain written into:

• purchase orders 
• tender specifications 
• vendor qualification forms 
• supply contracts 
• technical schedules 
• material specifications. 

If such a document refers to a standard scheduled for withdrawal, the team should review the wording before making a change.

A BIS revision does not automatically rewrite an existing contract.

The contract, customer requirement and regulatory position need to be looked at together.

Impact on Importers and Suppliers

The notification itself does not create a new import restriction.

Still, importers dealing with the covered products should check whether Indian customer specifications or regulatory documents refer to one of the revised standards.

A useful internal check is to ask:

• Which Indian Standard is written on the current technical file? 
• Is an older edition still being used? 
• Does a Quality Control Order cover the product? 
• Does the supplier's test report refer to another edition? 
• Does the buyer require a specific Indian Standard? 
• Is BIS certification separately applicable? 

These checks can help prevent a shipment or supply arrangement from being supported by outdated technical documentation.

What Manufacturers Should Review Before 28 February 2027

Businesses using the five standards scheduled for withdrawal can take the following practical steps.

1. Find Every Reference to the Older Standard

Search internal documents for:

• IS 302-2-24:1994 
• IS 8625-1986 
• IS 9748-1981 
• IS 10970-1984 
• IS 16384:2017 / ISO 21181:2013 

This gives the business a clear picture of where the transition may matter.

2. Obtain and Study the Revised Standard

Do not update a test or product file based only on the Gazette title. The technical team needs the actual revised standard to understand what has changed.

3. Check Testing Documents

Look at:

• SOPs 
• internal test methods 
• laboratory reports 
• inspection formats 
• acceptance criteria where relevant. 

4. Review Purchase and Supplier Requirements

Check whether procurement teams or suppliers still work to the old edition.

5. Look at Contracts and Tenders

Where an older standard is written into a contract, the commercial and technical teams should review the wording before changing it.

6. Verify Whether Certification Is Separately Mandatory

A BIS certification consultant or internal regulatory team can first check whether the specific product falls under a separate mandatory BIS requirement. This avoids beginning a certification process that may not actually apply.

7. Keep the Withdrawal Date Visible

For the five revised standards, the relevant withdrawal date is 28 February 2027.

Practical BIS Standards Transition Checklist

What This BIS Notification Does Not Introduce

This section is important because standards notifications are often mistaken for certification orders.

The Gazette itself does not expressly create:

• a new BIS registration portal 
• blanket mandatory certification for all six standards 
• an application document list 
• a new application fee 
• a new certification fee 
• a licence-validity period 
• renewal conditions 
• a new inspection process 
• a list of testing laboratories 
• a new standalone penalty 
• a universal filing deadline. 

Its main function is to establish the listed standards and provide the withdrawal position for specified earlier editions.

What Are the Practical Benefits of Updated Standards?

A revised standard gives businesses a current technical reference, but the actual benefit depends on how the standard is used.

Possible practical advantages include:

• More Current Technical References

Businesses can gradually remove obsolete editions from technical files and testing documents.

• Better Alignment With Newer International References

The Gazette expressly links some Indian Standards with newer ISO or IEC editions.

• Clearer Standard Transition

For five standards, businesses know the date on which the previous edition is scheduled for withdrawal.

• Better Internal Document Control

Engineering, quality, procurement and compliance teams can work towards using consistent references rather than different editions across departments.

• Fewer Outdated References in Procurement

Reviewing tenders and purchase specifications can reduce confusion between buyers and suppliers over which standard is being requested.

These are practical benefits rather than guaranteed commercial outcomes.

Challenges Businesses May Face During the Transition

Changing a standard reference can involve more work than editing a number in a document.

• Understanding What Has Actually Changed

A Gazette entry identifies the standard, but it does not reproduce all technical differences between editions. Businesses may need technical experts to compare the documents.

• Updating Testing Procedures

Where test methods have changed, laboratories and quality teams may need to review their internal procedures.

• Finding Old References Across Departments

The same older standard may appear in engineering, quality, procurement and commercial documents.

• Supplier Coordination

Vendors may continue using older specifications unless the buyer communicates the updated requirement clearly.

• Contractual Issues

A contract may expressly name a particular edition. Changing that reference without reviewing the contract could create confusion. No transition cost is stated in the Gazette, so a fixed compliance cost cannot be taken from this notification.

Business Opportunities Around Revised BIS Standards

Standards revisions can also increase demand for specialised technical and regulatory support.

Relevant service areas may include:

• BIS applicability assessment 
• standard-gap assessment 
• technical document review 
• product regulatory consulting 
• test-method review 
• laboratory coordination 
• compliance gap assessment 
• product compliance services. 

The opportunity is mainly in helping businesses understand what applies and what needs to change.

It should not be presented as a compulsory demand for BIS certification because this Gazette, on its own, does not establish that for all six standards.

What Businesses Should Monitor Next

This notification should not be treated as the final answer to every product-compliance question.

Affected businesses may need to continue checking official sources for:

• BIS amendments 
• corrigenda 
• further standard revisions 
• Quality Control Orders 
• changes in certification schemes 
• product-specific regulatory directions. 

A new or revised Indian Standard can exist before, alongside or independently of a separate mandatory certification requirement.

That is why product-level regulatory checking remains important.

What Businesses Should Do Next

A practical order for handling the notification is:

Priority 1: Check Whether the Standard Is Relevant

First identify whether the business manufactures, tests, purchases, imports or supplies something connected with any of the six standards.

Priority 2: Locate Older Standard References

Find where the old edition appears inside the organisation.

Priority 3: Review the 2026 Edition

The technical team should compare the revised edition instead of making changes based solely on the notification.

Priority 4: Examine Testing and Product Documents

Check test procedures, technical files and quality records.

Priority 5: Verify Mandatory Compliance Separately

Determine whether a QCO, BIS certification requirement or another legal instrument applies.

Priority 6: Plan Around 28 February 2027

Where one of the five previous standards is used, keep its withdrawal date visible in the transition plan.

How Can Corpseed Help with BIS and Product Compliance?

A revised BIS standard raises two different questions for a business.

The first is technical: Which standard should be reviewed?

The second is regulatory: Does the product actually require mandatory certification or another approval?

Corpseed can support businesses through product compliance services, BIS applicability reviews and technical compliance assistance based on the specific product involved.

BIS Applicability Assessment

Before starting any BIS application, the regulatory position should be checked.

Corpseed can help assess:

• product classification 
• applicable Indian Standard 
• whether a Quality Control Order covers the product 
• whether BIS certification is mandatory 
• whether certification is voluntary or not applicable 
• which version of the standard is relevant. 

This is particularly useful when a business sees a new BIS notification but is unsure whether it actually creates a filing requirement.

BIS Certification Services

Where a separate legal requirement makes BIS certification compulsory, Corpseed can assist with the relevant BIS certification services.

Support may include:

• understanding the applicable certification route 
• application preparation 
• document review 
• testing coordination where required 
• communication and filing support. 

The certification route depends on the product and applicable regulation. The six-standard notification itself should not be treated as proof that certification is mandatory.

Product Compliance Services

Corpseed's product compliance services can help manufacturers and importers look beyond the standard number and understand the wider regulatory position.

Support may cover:

• identifying relevant technical standards 
• checking regulatory applicability 
• reviewing technical documentation 
• identifying compliance gaps 
• planning further regulatory action. 

This is especially useful where several technical, certification or sector-specific requirements may apply to the same product.

Technical Compliance Consulting

Moving from an older standard to a revised standard can affect more than one department.

Through technical compliance consulting, Corpseed can support businesses in reviewing where an older standard is still referenced and which areas should be examined by engineering, testing or quality teams.

Compliance Gap Assessment

A compliance gap assessment can help identify the difference between the business's current technical references and the updated regulatory position.

The review may include:

• product documentation 
• test references 
• internal specifications 
• procurement documents 
• supplier records 
• relevant regulatory requirements. 

The purpose is to identify the areas that need attention rather than make unnecessary changes across every document.

Testing and Laboratory Coordination

Where testing is required under an applicable standard, certification scheme or customer requirement, Corpseed can assist with coordination around the testing process.

The actual:

• test method 
• test parameters 
• laboratory requirements and 
• acceptance criteria 

must come from the relevant standard and applicable regulatory framework.

Manufacturer and Importer Compliance Support

Manufacturers and importers often have to connect technical standards with product-specific legal requirements.

Corpseed can assist in checking whether a revised standard affects:

• existing certification 
• product documentation 
• testing 
• supplier records 
• import compliance 
• market-entry requirements. 

Businesses that are unsure whether the 2026 BIS standards affect their products can use product compliance services or consult a BIS certification consultant for a product-specific applicability review before beginning a certification or technical transition exercise.

Key Takeaways

The main point of this notification is straightforward: BIS has established six Indian Standards, while five older standards are scheduled to leave the framework on 28 February 2027.

Businesses should focus first on where these standards are actually used inside their operations.

• All six standards were established on 28 August 2026. 
• The BIS notification is dated 1 September 2026. 
• Five older standards are scheduled for withdrawal on 28 February 2027. 
• IS 228 (Part 37):2026 / ISO 10280:2025 has no earlier standard or withdrawal date listed. 
• The standards cover six different technical areas rather than one industry. 
• Businesses should review testing, technical, quality, procurement and supplier documents where an older standard is still used. 
• The Gazette should not automatically be treated as a blanket mandatory BIS certification order for all six standards.
