The Bureau of Indian Standards (BIS) has released an important update concerning the implementation of the IS 16242 (Part 1):2025 standard. This update pertains to the safety requirements for Uninterruptible Power Systems (UPS) and ensures alignment with international standard IEC 62040-1:2017, including its amendments.
Background
Earlier, BIS issued a circular on 21 August 2025 regarding the implementation of IS 16242 (Part 1):2025 / IEC 62040-1:2017. However, as per the latest circular dated 10 October 2025, the standard number must now be read as: IS 16242 (Part 1):2025 / IEC 62040-1:2017 + AMD1:2021 + AMD2:2022 CSV
This correction incorporates the latest amendments to the international standard, ensuring that manufacturers, testing laboratories, and certification bodies are all aligned with the most current technical and safety specifications.
Key Update
The correct version of the standard is now: IS 16242 (Part 1):2025 / IEC 62040-1:2017 + AMD1:2021 + AMD2:2022 CSV
All other terms and conditions mentioned in the previous circular dated 21 August 2025 remain unchanged.
Impact on Manufacturers and Stakeholders
This update is particularly important for:
- Manufacturers of Uninterruptible Power Systems (UPS), who must ensure compliance with the revised standard for BIS certification.
- Testing laboratories, which should refer to the updated version while conducting product evaluations.
- Importers and exporters, who need to align with the latest BIS and IEC safety requirements for UPS systems.
Why This Update Matters
Adopting the latest version of the standard enhances product safety, consumer trust, and global compatibility. It ensures that products tested and certified under BIS comply with the most recent international safety benchmarks.
Conclusion
The BIS continues its efforts to harmonize Indian Standards with global norms, fostering quality, safety, and innovation in the Indian electronics industry. Stakeholders are advised to review this update and make necessary changes in their processes to ensure compliance.
