How IS 9968 testing works
- Tell us the purpose. BIS certification, a tender, a customer requirement or a design check. The purpose decides which clauses and which laboratory.
- Get the sample list and quote. We confirm the tests, the number of samples and the timeline for your product and its variants.
- Send samples. We help with labels, the test request and any technical documents the tests need.
- Testing and report. Tests are carried out under NABL accreditation and the report lists each clause, the requirement and the result.
- Review and use. We check the report before you submit it to BIS, a tender authority or your customer, and help if they raise a query.
Need the ISI mark or CRS registration as well? See IS 9968 BIS certification for the products covered, the order, fees and process.
Frequently asked questions
Which IS 9968 tests are NABL accredited?
All 54 tests listed on this page are within NABL accreditation (ISO/IEC 17025), each against the clause of IS 9968 shown next to it. The report carries the NABL accreditation mark for these tests.
Can the IS 9968 test report be used for BIS certification?
Yes. Testing to IS 9968 is available at a BIS-recognised laboratory, so the report can be submitted with a BIS application. BIS may still draw its own samples during the factory inspection.
How many samples are needed for IS 9968 testing?
It depends on the product, its variants and the tests you need. Share the product details and the purpose of the test (BIS, tender or customer) and we will send the sample list and a quote.
Can you test only some clauses of IS 9968?
Yes. For a tender, a customer complaint or a design check, we can test selected clauses. For BIS certification or a type test, every applicable clause has to be covered.
