Testing against IS 16169

Samples are type-tested at a BIS-recognised laboratory in India; foreign lab reports are not accepted. BIS then reviews the test report and documents and grants the registration. Market surveillance samples follow.

The test report has to cover every clause of IS 16169 that applies to the product, in the edition current on the date of testing. When BIS revises IS 16169 or replaces it with a new edition, existing licence holders move to the new edition by the date BIS sets in its notification.

How to get CRS registration under IS 16169

  3. Apply on the CRS portal with the test report, factory and brand documents
  4. BIS review and grant of the R-number registration
  5. Mark products with the Standard Mark, IS number and R-number
