IS/IEC 62368-1:2023: How to Handle Series Models in BIS CRS Migration

Series models — product variants registered under a lead model in BIS CRS — need careful strategy for IS/IEC 62368-1:2023 migration. Here is how to handle large product portfolios efficiently.

What Are Series Models in BIS CRS?

BIS CRS allows a lead model (fully tested) to cover similar variants (series models) without full independent testing of each. Examples: laptop in 8GB/16GB RAM (same chassis), TV in 32"/43"/55" (same circuit platform), power bank in 10,000/20,000 mAh versions.

Migration Requirements for Series Models

  • Lead model: complete IS/IEC 62368-1:2023 test report required
  • Series models: signed undertaking/declaration confirming all series models comply with IS/IEC 62368-1:2023
  • Undertaking must identify all covered series models

Efficient Strategy for Large Portfolios

  1. Group products by platform (common chassis, power design, battery)
  2. Identify one representative lead model per platform group
  3. Test the lead model under IS/IEC 62368-1:2023
  4. Cover all platform variants with an appropriate undertaking
  5. Confirm series coverage approach with BIS-recognized lab before submitting

When Series Coverage Is Not Sufficient

Variants with significantly different power handling, battery design, or safety-critical components may need independent testing. Confirm the threshold with your lab. MeitY revised series guidelines expected — watch for publication and update your strategy accordingly.
