How BS EN 50397 testing works
- Tell us the purpose. Export, 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 a regulator, a tender authority or your customer, and help if they raise a query.
Frequently asked questions
Which BS EN 50397 tests are NABL accredited?
All 54 tests listed on this page are within NABL accreditation (ISO/IEC 17025), each against the clause of BS EN 50397 shown next to it. The report carries the NABL accreditation mark for these tests.
Is the BS EN 50397 test report accepted outside India?
NABL is a signatory to the ILAC Mutual Recognition Arrangement, so its accredited reports are recognised by accreditation bodies in other member countries. Your buyer or regulator still decides what it accepts, so we confirm their requirement before testing.
How many samples are needed for BS EN 50397 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 BS EN 50397?
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.
