IATF 16949:2016 External Laboratory - How to approve the Testing Laboratory without accreditation scope

Ng Hang

Currently my company is using the testing laboratory (separated company), but it is in Corporate, this laboratory does not have any ISO Standards (such as ISO/IEC 17025) or national equivalent.
So we are preparing documents (lab scope, test, capability to perform the required inspection,...) as evidences to submit to customer for approval instead of ISO certificate to comply clause in IATF Requiments.

Could you advise us what kinds of detail documents we must prepare? If possible, could you give us an example file about it?

Thank you so much.


Simple then: You need to:
  1. Provide the scope of the lab
  2. Provide all the capabilities of the lab
  3. Provide evidence that all the measurements you complete meet the requirements of the "ISO standard or national equivalent"
  4. Where relevant provide MSA studies for the measurements
  5. Have a process in place for handling measurements that are not meeting the criteria.
  6. Finally, have fundamental QMS in place for that lab - doc control, traceability, mgt review, maintenance, etc.


Similar topic. We are an IATF certified automotive supplier. Due to the COVID shutdowns, production has been slow. A customer asked us if we had CMM capacity to do some inspection sorting for them. We didn't want to pass up some work, so we took their CMM program and duplicated on our CMMs. All we are doing is taking parts from customer, inspecting part for 1 feature (perpendicularity) and separate good vs bad before returning. We completed a successful gage RR and correlation with the customer CMM. Plan is to complete a basic PPAP package of the process with PSW for customer to sign off on. Internal concerns have been raised in regards to us not having ISO-17025 accreditation. We do have lab scope for our in-house calibrations and routine inspections. Surveillance audit is about a month away so looking for some input on legitimacy of this project and additional requirements, if any, we should have in place.
Appreciate any like experiences that could be shared.
