We have a small calibration room for our Deadweight tester, which is use to calibrate gauges that are used on our aircraft ground support equipment. The DWT is regularly serviced and calibrated to UKAS standards and is included in our QMS (ISO 9001:2015). However some of our customers are now stating we should be ISO 17025 accredited as well. I note 17025 is being reviewed to bring it inline with the Annex SL structure, is there any time scale for its introduction. I would rather try to expand our existing 9001:2015 QMS to include the 17025 technical laboratory requirements rather than having to write a another complete QMS for a Laboratory to the old style? Many thanks for any advise you can offer.
