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
- Group products by platform (common chassis, power design, battery)
- Identify one representative lead model per platform group
- Test the lead model under IS/IEC 62368-1:2023
- Cover all platform variants with an appropriate undertaking
- 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.
