Testing against IS 17412
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 17412 that applies to the product, in the edition current on the date of testing. When BIS revises IS 17412 or replaces it with a new edition, existing licence holders move to the new edition by the date BIS sets in its notification.
