BIS CRS requires BIS-recognized labs. NABL accreditation alone doesn't qualify. WPC ETA needs WPC-recognized or ILAC MRA labs. Using an unqualified lab means test reports will be rejected, and you'll need to re-test from scratch — adding weeks and cost.

Recognition is product-category and standard-specific — a lab may be BIS-recognized for IS 13252 but not for IS 9873. **Used for:** BIS CRS and ISI Mark certification testing. Test reports from BIS-recognized labs are mandatory for BIS applications. **How to verify:** Check the BIS list of recognized labs on bisapplications.bis.gov.in or the BIS portal. ### NABL-Accredited Laboratory Accrediting body: National Accreditation Board for Testing and Calibration Laboratories (NABL) NABL is India's accreditation body, a signatory to ILAC MRA. NABL accreditation means the lab follows ISO/IEC 17025 quality management. NABL accreditation alone does not make a lab BIS-recognized. **Used for:** BEE energy performance testing requires NABL-accredited labs. CDSCO may accept NABL-accredited labs for certain medical device tests. NABL is the quality foundation underlying most recognized labs. **How to verify:** Check lab accreditation scope at nabl.gov.in. Verify the specific test parameters and standards in the scope. ### WPC-Recognized Laboratory (for ETA) Accrediting body: Wireless Planning and Coordination Wing (WPC) WPC maintains its own list of recognized labs for RF testing used in ETA applications. Many are NABL-accredited and ILAC-recognized. **Used for:** WPC ETA applications. RF test reports must come from WPC-recognized or ILAC-accredited labs. **How to verify:** Check WPC recognized lab list on dot.gov.in or Saral Sanchar portal. ### TEC-Recognized Laboratory (for MTCTE) Accrediting body: Telecommunication Engineering Centre (TEC) TEC maintains a list of labs specifically recognized for MTCTE testing against Essential Requirements. **Used for:** TEC MTCTE certification testing. Test reports must be from TEC-recognized labs. **How to verify:** Check TEC MTCTE portal (mtcte.tec.gov.in) for the lab list. ### ILAC MRA Accredited Laboratory (Overseas) Accrediting body: International Laboratory Accreditation Cooperation (ILAC) member accreditation bodies Labs accredited by ILAC MRA signatories (e.g., A2LA, UKAS, DAkkS, CNAS) may be accepted for BIS CRS and WPC ETA applications as alternatives to India-based recognized labs. **Used for:** BIS CRS for foreign manufacturers: ILAC-accredited labs outside India are often accepted if also BIS-recognized for the specific product standard. WPC ETA: ILAC MRA labs generally accepted. **How to verify:** Check if the overseas accreditation body is an ILAC MRA signatory. Check if BIS has recognized the specific overseas lab for the relevant IS standard. ## Lab selection criteria ### Certification target Match the lab type to your certification: BIS CRS → BIS-recognized lab; WPC ETA → WPC-recognized/ILAC lab; TEC MTCTE → TEC-recognized lab; BEE → NABL-accredited lab. ### Scope for your specific product category and IS standard A lab BIS-recognized for IS 13252 may not be recognized for IS 9873. Verify the specific IS standard is in the lab's BIS recognition scope before shipping samples. ### Lab turnaround time and capacity For fast-moving markets, turnaround time matters. Some BIS-recognized labs have 4–6 week backlogs for popular categories like mobile phones and IT equipment. ### Sample quantity and logistics Labs specify how many samples are needed. For overseas manufacturers, shipping cost and transit damage risk must factor into lab selection. Indian labs eliminate import logistics but overseas labs may offer faster scheduling. ### Combined certifications efficiency If you need both BIS CRS and BEE testing, select a lab that is both BIS-recognized and NABL-accredited for energy testing. Testing at one lab for both reduces logistics and cost. ## Frequently asked questions ### Can I use a CE-accredited European lab's test reports for BIS CRS in India? Potentially yes — if the European lab is ILAC MRA accredited (accredited by a body like DAkkS, UKAS, or similar ILAC signatory) AND is specifically recognized by BIS for the relevant IS standard. BIS maintains a list of recognized overseas labs. Many major European test houses (TÜV, SGS, Intertek, Bureau Veritas) have BIS recognition for key standards. Always verify BIS recognition for your specific IS standard before relying on overseas test reports. ### Does NABL accreditation automatically mean a lab's reports are accepted by BIS? No. NABL accreditation is a quality management credential (ISO/IEC 17025). BIS recognition is separate — it specifically authorizes a lab to issue test reports for BIS certification purposes. Many NABL-accredited labs are also BIS-recognized, but NABL accreditation alone is insufficient for BIS CRS applications. Always check BIS recognition in addition to NABL accreditation. ### How do I find a BIS-recognized laboratory for my product category? The BIS portal (bisapplications.bis.gov.in) maintains a searchable list of BIS-recognized laboratories by product category and IS standard. You can filter by state, lab type, and standard. Additionally, BIS district offices can advise on recognized labs in your region. For overseas manufacturers, ask your Authorized Indian Representative (AIR) for recommendations on labs recognized for your specific IS standard — AIRs active in your product category will have direct experience. **Disclaimer:** Lab recognition lists are maintained by BIS, WPC, TEC, and NABL and updated periodically. Always verify current lab recognition status on the respective regulator's official portal before sending product samples. 🇮🇳 India roadmap for your product Every standard, document, and test that applies — free, no account required.
