**Executive Summary**
This notification by the Bureau of Indian Standards (BIS), dated April 2, 2026, announces the establishment of four updated or new Indian Standards effective from March 30, 2026. It specifies that previous versions of these standards will remain in force concurrently until their scheduled withdrawal on September 30, 2026. The document serves as official notice under the Bureau of Indian Standards Rules, 2018.

* Reference number: HQ-PUB013/1/2020-PUB-BIS (1523).
**Revised Standards for Welding and Construction**
* **IS 813 (Part 1) : 2026 / ISO 2553 : 2019**: This third revision covers symbolic representation on drawings for welded joints. It replaces the 2018 version.
* **IS 11682 : 2026**: This first revision establishes criteria for the design of reinforced concrete staging for elevated liquid storage tanks, replacing the 1985 version.
**Standards for Raw Materials and Industrial Components**
* **IS 8604 : 2026**: This first revision defines the method of test for determining the compression strength of iron ore pellets after reduction, replacing the 1977 version.
* **IS 19773 : 2026**: A new specification established for high chrome grinding media balls used in cement mills.
**Transition and Withdrawal Timeline**
* **Establishment Date**: All new standards listed were established on March 30, 2026.
* **Concurrent Force**: Superseded standards (for IS 813, IS 11682, and IS 8604) will remain valid alongside new versions until the withdrawal date.
* **Withdrawal Date**: The older versions of the revised standards will be officially withdrawn on September 30, 2026.
**Impact Analysis**
**Manufacturers and Industrial Engineers**
**Impact**
Entities involved in welding, concrete tank construction, iron ore processing, and cement milling must align their technical processes and symbolic representations with the 2026 revisions.
**Action Required**
Must update internal design manuals, procurement specifications, and production standards to comply with the 2026 versions before the September 30, 2026, deadline.
**Testing Laboratories and Quality Inspectors**
**Impact**
Testing protocols and certification criteria must be updated to reflect the revised testing methods (e.g., iron ore pellet compression) and new specifications (high chrome grinding media).
**Action Required**
Calibrate testing equipment and update standard operating procedures (SOPs) to meet the requirements of the 2026 standards.
**Regulatory and Compliance Bodies**
**Impact**
Ensures that all certifications and legal oversight are based on the most current safety and technical benchmarks.
**Action Required**
Monitor the transition period and ensure that all industry stakeholders cease use of the withdrawn 1977, 1985, and 2018 versions by the September 30, 2026, cutoff.
