Re: Is ISO17025-accreditation necessary condition for lab's of aviation repair statio
If your in-house calibration lab calibrates tooling, according to EASA Part 145 it says:
10.2.3. Calibration in accredited laboratories
In order to comply with Part-145.A.40 (b) the maintenance organisation shall ensure that:
(a) tooling are periodically calibrated in accordance with the manufacturers’ published standards and recommendations.
(b) where no recommendations for calibration are published or where the calibration methods or standards are not specified, calibration is carried out in accordance with the requirements of the ISO 10012. This standard details both the generic requirements and guidance for the implementation of measurement management systems.
Both (a) and (b) above shall require the tooling to be calibrated in a test laboratory accredited to the ISO/IEC 17025 standard, by an accreditation body acceptable to the European Aviation Safety Agency.
Only a laboratory accredited by an “Accreditation body” which is signatory of the ILAC MRA is considered acceptable to EASA, considering that in this case traceability through the assessment and accreditation process under ISO/IEC 17025 has already been established.
It states that the lab calibrating the tooling must be 17025 accredited via an ILAC AB. Doesn't matter if internal or external, it must be accredited.
