* IS 18349 Part 3:2025 referencing ISOTS 152133:2024 (Microbiology of the Food Chain Horizontal Method for the Detection and Enumeration of Clostridium Spp. Part 3 Detection of Clostridium perfringens)
* IS 19353:2025 referencing ISOTS 17728:2015 (Microbiology of the Food Chain Sampling Techniques for Microbiological Analysis of Food and Feed Samples)
Impact Analysis:
Textile Manufacturers:
* Impact: Must adhere to the updated specifications for blanketing cloth and yarn, as outlined in IS 1531:2025 and IS 1670:2025, respectively.
* Action Required: Implement the new standards and ensure compliance by February 26, 2026, when the previous standards are withdrawn.
Water Quality Testing Laboratories:
* Impact: Must adopt the new methodologies for water quality testing as per the established Indian Standards referencing various ISO standards.
* Action Required: Implement the new testing procedures and ensure that laboratory practices align with the new standards.
Food Microbiology Laboratories:
* Impact: Must adopt the new methodologies for detection and enumeration of Clostridium spp. and sampling techniques for microbiological analysis of food and feed samples.
* Action Required: Implement the new testing procedures and ensure that laboratory practices align with the new standards.
Bureau of Indian Standards (BIS):
* Impact: Responsible for the enforcement and oversight of the newly established standards.
* Action Required: Ensure the effective implementation and monitoring of compliance with the new standards across relevant industries.
