FAQ

NABL / NABH: frequently asked questions

What is the difference between NABL and ISO 17025?

ISO 17025 is the international standard for laboratory competence. NABL accreditation is the Indian national program based on ISO 17025. Getting NABL accreditation demonstrates compliance with ISO 17025 in the Indian context.

Is NABL accreditation mandatory for testing laboratories in India?

It depends on the sector and the regulator or customer. Several government departments and regulators require NABL-accredited test results for specific tests, and many tenders ask for them. Check the requirement that applies to your laboratory.
