India’s Bureau of Indian Standards (BIS) has announced the adoption of IS 16242 (Part 1):2025/IEC 62040-1:2017, which will supersede the current IS 16242 (Part 1):2014/IEC 62040-1:2008. The revised standard, aligned with IEC 62040-1:2017, introduces updated safety requirements for uninterruptible power systems (UPS) and mandates full implementation by 19 November 2025.
After this date, the previous standard will be withdrawn, and only products compliant with the 2025 version will be eligible for BIS certification.
Implementation Guidelines for Licensees and Applicants
Existing Licensees:
All licensees must transition to the new standard by the 19 November 2025 deadline.
Compliance must be demonstrated through:
Updated test reports for all lead models from BIS-recognized laboratories.
An undertaking confirming that other series models also conform to the revised requirements.
Failure to meet these requirements will result in license cancellation or the deletion of non-compliant models from the license scope.
New Applicants:
Applications already submitted with testing underway may still be processed under the old standard.
New applications recorded before the deadline may choose either standard; however, any approvals issued under the older version will require written commitment to upgrade by the implementation deadline.
After 19 November 2025, all new applications must comply with the revised 2025 edition.
Scope Changes:
Requests to modify the scope of a license will follow the same rules as new applications.
Scope expansions using the older standard will only be allowed until the licensee transitions or the deadline is reached, whichever is earlier.
Key Technical Revisions in the 2025 Standard
The updated IS 16242 (Part 1):2025 introduces several enhancements based on IEC 62040-1:2017. Notable regulatory and technical changes include:
Use of IEC 62477-1:2012 as a reference document.
Addition of the definition for “movable UPS”.
Revised requirements for enclosure material flammability.
Updates to creepage distance testing with added working voltage levels.
Enhanced criteria for steady force, handle strength, and manual control tests.
New protocols for touch current and input current measurements.
Modified capacitor discharge testing, now distinguished by UPS connection type (pluggable vs. permanently connected).
Additional environmental and safety tests:
Short time withstand current
Load transfer (unsynchronized)
Loss of coolant
Dry heat and damp heat tests
Hydrostatic pressure evaluation
These changes reflect a stronger emphasis on user safety, equipment durability, and environmental resilience.
