Testing against IS 2141

BIS inspects the factory and has samples tested to the full Indian Standard at a BIS or BIS-recognised laboratory. After grant, the factory keeps testing production under the Scheme of Inspection and Testing, and BIS draws factory and market samples.

The test report has to cover every clause of IS 2141 that applies to the product, in the edition current on the date of testing. When BIS revises IS 2141 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 an ISI mark licence under IS 2141
