BIS Corrigendum 2026: New Withdrawal Dates for Masonry Cement and Vibration Machine Standards

The Bureau of Indian Standards (BIS) has extended the withdrawal dates of two older Indian Standards used in the cement and construction-material testing sectors. The changes were published in the Gazette of India on 16 October 2026, and relate to masonry cement and vibration machines used for casting standard cement mortar cubes.

Under the BIS Corrigendum 2026, the withdrawal date of IS 3466:1988, which covers masonry cement, has been revised to 20 March 2027. The withdrawal date of IS 10080:1982, relating to vibration machines, has been extended to 27 February 2028. Both standards were previously scheduled for withdrawal on 20 September 2026.

For manufacturers, testing laboratories and equipment suppliers that still refer to these older standards, the revised dates are important. They provide additional time to review the newer editions and decide whether changes are needed in technical specifications, testing procedures or certification records.

However, the corrigenda do not automatically extend mandatory BIS certification deadlines or introduce new certification requirements.

BIS Corrigendum 2026: Notification at a Glance

The October corrigenda amend two entries in a BIS notification originally issued on 23 March 2026.

These amendments apply to specific entries in the original notification. They should not be treated as a general extension for all products covered by BIS.

Why Has BIS Revised the Withdrawal Dates?

When BIS revises an Indian Standard, the older edition may remain in force alongside the new edition for a limited period. This allows users to understand the revised requirements, and consider whether changes are needed in their existing technical practices.

In March 2026, BIS published a notification establishing several updated Indian Standards. The notification also identified the older editions that would eventually be withdrawn.

Two of those older editions were IS 3466:1988 and IS 10080:1982. Their original withdrawal dates were set for 20 September 2026.

Through the October corrigenda, BIS has given these standards new withdrawal dates.

The notifications do not explain why the extensions were granted. However, from a business-planning perspective, the revised dates provide a longer period during which the older editions remain in force.

Manufacturers and laboratories can use this period to review the newer editions, examine their current documents and prepare for any necessary changes.

What Has Changed Under the October 2026 BIS Corrigendum?

The two amendments concern different standards, and each has its own revised withdrawal date.

Masonry Cement: IS 3466:1988 Withdrawal Extended to March 2027

Masonry cement is used in construction work, particularly for preparing mortar used in activities such as bricklaying and plastering.

The earlier Indian Standard for this material was IS 3466:1988- Specification for Masonry Cement (Second Revision).

On 20 March 2026, BIS established the revised standard, IS 3466:2026- Masonry Cement- Specification (Third Revision).

The older edition was originally scheduled for withdrawal on 20 September 2026. Under Corrigendum HQ-PUB-BIS (1622), the withdrawal date has now been changed to 20 March 2027.

This means that the 1988 edition remains in force for a longer period alongside the 2026 edition.

Manufacturers using the older standard should examine the revised specification and check whether their product documents or quality-control procedures need to be updated.

Importantly, the extension does not mean that any separate mandatory certification requirement has also been extended.

Vibration Machines: IS 10080:1982 Withdrawal Extended to February 2028

The second amendment extends the withdrawal date of IS 10080:1982, which covers vibration machines used to prepare standard cement mortar cubes for testing. These machines are used in cement-testing laboratories to prepare mortar samples for testing. The extended date gives affected laboratories and organisations more time to review the standard and make any necessary changes.

The earlier standard was IS 10080:1982- Specification for Vibration Machine.

BIS established its revised edition, IS 10080:2026- Vibration Machine for Casting Standard Cement Mortar Cubes- Specification (First Revision), on 20 March 2026.

The withdrawal of the older edition was initially scheduled for 20 September 2026.

Under Corrigendum HQ-PUB-BIS (1621), the new withdrawal date is 27 February 2028. This gives organisations using the older edition more time before its withdrawal. Testing laboratories, machine manufacturers and technical suppliers should still check whether their existing procedures and equipment specifications align with their applicable requirements.

BIS Standards Withdrawal Dates: Old vs New

The following table explains the changes made through the two corrigenda.

Both revised editions, IS 3466:2026 and IS 10080:2026, were established on 20 March 2026.

The October 2026 corrigenda have not changed those establishment dates. Only the withdrawal dates of the older editions have been amended.

Which Manufacturers and Businesses Are Affected?

The BIS notification is particularly relevant to businesses and technical organisations that use masonry cement standards or vibration machines for cement-testing work.

Masonry Cement Manufacturers
Businesses manufacturing masonry cement may refer to IS 3466 in their product specifications, testing documents and quality-control systems.

The extended withdrawal date gives them additional time to examine IS 3466:2026 and assess whether their existing processes need revision.

Manufacturers should also check whether any certification or product-specific requirement applies independently of the standard withdrawal date.

Cement Testing Laboratories
Laboratories that prepare or test cement mortar cubes may use equipment or procedures referring to IS 10080.

The revision is relevant when reviewing equipment specifications, technical procedures and standard references.

However, an extended withdrawal date does not automatically change the requirements of an applicable laboratory accreditation or testing scheme.

Vibration Machine Manufacturers and Suppliers
Manufacturers and suppliers of vibration machines covered by IS 10080 should examine the revised 2026 edition.

They may need to review technical specifications, product documentation and customer requirements.

The exact changes needed will depend on the differences between the standard editions and the requirements applicable to their equipment.

Importers and Procurement Teams
Importers and buyers dealing with relevant construction materials or testing equipment should check which edition of the Indian Standard is specified in their purchase orders and technical contracts.

The October corrigenda do not introduce a new import licence or registration requirement.

Businesses must assess any existing import or product certification obligations separately.

Does the BIS Corrigendum Change Mandatory Certification Requirements?

There is an important difference between an Indian Standard and mandatory BIS certification.

An Indian Standard sets out technical requirements, methods or specifications relating to a particular product or activity.

Mandatory BIS certification applies when a relevant legal instrument requires a product to undergo conformity assessment under an applicable scheme.

The October 2026 corrigenda deal with the withdrawal of two older Indian Standards.

They do not expressly introduce:

• A new mandatory BIS certification requirement.
• A new BIS registration process.
• Additional product certification fees.
• New technical testing conditions.
• A new exemption from an existing certification obligation.

Businesses should therefore avoid assuming that the revised withdrawal dates automatically change the legal deadlines under any applicable Quality Control Order.

Where BIS certification is already required, manufacturers should confirm the applicable standard edition and certification conditions.

The withdrawal date of a standard and the deadline for obtaining mandatory BIS certification are not necessarily the same.

How Will the Revised BIS Standards Affect Businesses?

Although the corrigenda are limited to two date changes, businesses using the affected standards may need to review their existing arrangements.

More Time to Review Technical Specifications
The revised dates provide a longer period during which the older standards remain in force.

Manufacturers can review the new editions and examine how they compare with the specifications currently used in their operations.

This may involve checking product requirements, equipment documentation or testing procedures.

Changes in Product Documentation
Some businesses may still refer to the older standards in internal documents, procurement specifications or technical records.

Where necessary, those references should be reviewed.

The October corrigenda do not themselves require every business to replace all such documents immediately. The appropriate action depends on the applicable standard, contract and regulatory conditions.

Implications for Testing Laboratories
Testing laboratories should pay particular attention to IS 10080:2026 if their equipment or test procedures refer to the older edition.

A review may help determine whether changes are needed to equipment specifications, calibration-related documentation or laboratory procedures.

The actual technical requirements must be checked against the relevant standards and accreditation conditions.

BIS Certification Planning
Businesses searching for BIS certification services in India should first establish whether certification is compulsory for their products.

If certification is required, they may need to assess the applicable standard, testing requirements, documents and certification procedure.

The October corrigenda do not replace that assessment.

What Should Businesses Do Before the Revised Withdrawal Dates?

Manufacturers, suppliers and laboratories should use the extended period to understand the requirements relevant to their operations.

The following steps can help businesses prepare.

• Check the applicable Indian Standard: Identify whether your business uses IS 3466:1988 or IS 10080:1982. If neither standard is relevant, these particular amendments may not affect your operations.
• Review the latest edition: Examine IS 3466:2026 or IS 10080:2026, as applicable. Compare the revised edition with the standard currently referenced in your technical documents.
• Check existing BIS certification requirements: Determine whether the relevant product is subject to mandatory certification under a separate legal requirement. Do not rely only on the withdrawal-date notification.
• Review product and testing documents: Check product specifications, laboratory procedures, supplier requirements and technical records for references to the previous editions of the standard.
• Update compliance plans: Note the date on which the old standard will be withdrawn and decide what changes need to be made before that date.
• Check later official notifications: Before making final decisions, verify whether BIS has issued further amendments, or guidance affecting the relevant standard.

These steps are practical recommendations. They are not additional mandatory procedures introduced by the October corrigenda.

What Happens After the Revised BIS Withdrawal Dates?

Once an older Indian Standard reaches its notified withdrawal date, businesses should not assume that it continues to have the same status as a current Indian Standard.

For IS 3466:1988, the revised withdrawal date is 20 March 2027.

For IS 10080:1982, the revised withdrawal date is 27 February 2028.

Businesses should review whether the newer editions need to be reflected in technical documentation, testing arrangements or product specifications.

The effect on existing certification, contracts or approvals will depend on the requirements governing those arrangements.

The October corrigenda do not state that all products previously made or tested under the older editions will become illegal after withdrawal.

Any legal consequences must be established under the applicable law or certification conditions.
