The document presented corresponds to an official communication from the Bureau of Indian Standards (BIS) regarding the revision of the safety standard for uninterruptible power supplies (UPS).

It is reported that the IS 16242 (Part 1):2014 / IEC 62040-1:2008 standard has been replaced and updated as IS 16242 (Part 1):2025 / IEC 62040-1:2017, with definitive entry into force on November 19, 2025, at which date the previous version will be officially withdrawn.

The circular establishes clear guidelines for three main stakeholders: existing licensees, new applicants, and those requesting changes to the scope of their licenses.

WHOM DOES IT IMPACT?

The direct impact is on manufacturers, importers, licensees, end users, and industries that rely on UPS.

CONCLUSION:

The revision of the IS 16242 (Part 1):2025 / IEC 62040-1:2017 standard strengthens the safety and reliability of UPSs in India, harmonizing them with international standards. It represents a challenge for manufacturers due to the costs and adaptation times, but at the same time strengthens market confidence and raises the level of protection for users and critical infrastructure.
