In pursuance of Sub rule (1) of Rule (15) of the Bureau of Indian Standards Rules, 2018, the Bureau of Indian Standards hereby notifies that Indian standards
**Executive Summary**
The Bureau of Indian Standards (BIS) issued a notification on March 24, 2026, announcing the establishment of ten revised Indian Standards effective from March 23, 2026. These standards cover diverse sectors including thermometry, industrial chemicals, insulation, and photography. Existing standards mentioned in the schedule will remain in force concurrently until their final withdrawal date of September 23, 2026.
**Key Points / Main Content**
**Thermometry and Measurement Standards**
* **IS 2627:2026:** Establishes the second revision of the glossary for liquid-in-glass thermometers, replacing the 1979 version.
* **IS 7000:2026:** Sets specifications for general-purpose maximum and minimum thermometers (first revision), replacing the 1973 version.
* **IS 12244 (Part 2):2026:** Details specifications for calorimeter thermometers, specifically part 2 enclosed scale thermometers (first revision), replacing the 1988 version.
**Chemicals and Industrial Catalysts**
* **IS 7038:2026:** Provides specifications for Chloroplatinic Acid (Platinum chloride) in its first revision, replacing the 1973 standard.
* **IS 7130:2026:** Outlines technical specifications for Chlorosulphonic Acid in its third revision, replacing the 1994 version.
* **IS 8325:2026:** Establishes the second revision for Nickel Formate used for Nickel Catalyst, replacing the 1983 version.
**Insulation and Agricultural Manufacturing**
* **IS 3677:2026:** Specifies requirements for unbonded rock and slag wool for thermal insulation (third revision), replacing the 1985 standard.
* **IS 3894:2026:** Details specifications for manually-operated comb foundation mills (second revision), replacing the 1978 standard.
**Photography and Pre-Press Industry**
* **IS 12517:2026 (ISO 11312:2000):** Establishes dimensions and requirements for sheets of sensitized material used in the pre-press industry, replacing the 1988 standard for photographic film.
* **IS 12533:2026 (ISO 3772:2000):** Outlines dimensions and requirements for rolls of sensitized material for the pre-press industry, replacing the 1988 standard for paper sizes in phototypesetting and photolettering.
**Impact Analysis**
**Manufacturers and Industrial Producers**
**Impact**
Manufacturers of thermometers, industrial chemicals (Chlorosulphonic and Chloroplatinic acid), thermal insulation, and photographic materials are now subject to updated technical specifications and revisions. They are granted a transition period where old and new standards coexist.
**Action Required**
Producers must update their manufacturing processes and quality control protocols to align with the 2026 revisions. Full compliance must be achieved before the previous versions are officially withdrawn on September 23, 2026.
**Testing Laboratories and Quality Inspectors**
**Impact**
Testing facilities and certification bodies must update their parameters to reflect the new glossaries, dimensions, and specifications established in the revised standards.
**Action Required**
Laboratories must calibrate equipment and update testing methodologies to ensure they can certify products according to the 2026 revisions.
**Regulatory and Standards Bodies**
**Impact**
The BIS ensures that national standards remain current with technological advancements and international benchmarks (such as ISO alignments for photography materials).
**Action Required**
BIS will monitor the concurrent period and ensure the formal withdrawal of the specified older standards by the September 2026 deadline.
