Important Update: Revision of IS 16103 (Part 1) Guidelines

The Bureau of Indian Standards (BIS) has announced the revision of IS 16103 (Part 1):2012, which has now been updated and published as IS 16103 (Part 1):2025 / IEC 62031:2018. This standard pertains to LED modules for general lighting and ensures product quality, safety, and compliance with international benchmarks.

Key Timelines

• Concurrent running of both standards: Until 21 January 2026
• Withdrawal of IS 16103 (Part 1):2012: Effective after 21 January 2026
• Mandatory implementation: All licensees and applicants must comply with IS 16103 (Part 1):2025 / IEC 62031:2018 by this date.

Guidelines for Implementation

For Existing Licensees:

• Must transition to IS 16103 (Part 1):2025 by 21 January 2026.
• Required to submit test reports from BIS-recognized labs for all lead models previously tested as per the 2012 version.
• Need to provide an undertaking confirming implementation across all existing series models.

Implementation Guidelines

For Existing Licensees

• Mandatory Migration: Implement IS 16242 (Part 1):2025 / IEC 62040-1:2017 by 19 November 2025. Licences not demonstrating compliance by this date will not remain operative.
• Test Evidence: Submit complete test reports from BIS-recognized labs for all lead models previously tested to the 2014 edition.
• Series Models: Provide an undertaking that all other series models under licence also meet the 2025 edition.
• Non-compliance may lead to cancellation of licence or deletion of models from the scope.

For New Applicants:

• Ongoing applications with submitted samples/test reports may still be processed under the old standard.
• New applications can be processed under either the old or revised standard, but only until 21 January 2026.
• After this date, no licences will be issued under the old standard.

For Change in Scope of Licence:

• Same provisions as new applicants will apply.
• Requests under the old standard will only be permitted until the licensee’s switchover date or 21 January 2026, whichever is earlier.

Major Changes in IS 16103 (Part 1):2025

The revision introduces several important updates to enhance safety and usability:

• New definitions for replaceable, non-replaceable, and non-user replaceable LED modules
• Restructured marking requirements with an informative overview table
• Modifications in marking for built-in LED modules and working voltage entries
• Deletion of Annex B
• Additional information for luminaire design regarding working voltage and water contact
• Introduction of abnormal temperature tests
• Inclusion of photobiological safety tests

Conclusion

This revision brings the Indian Standard in alignment with international best practices, ensuring higher safety and reliability of LED modules in the Indian market. All stakeholders—including manufacturers, licensees, and new applicants—are encouraged to start implementing the revised standard well before the deadline.
