We have issued our own WPQR according to EN 15614-1, procedure is certified by Examiner and made tests at not-accredited laboratory according to ISO 17025.
We had carried out internal audit at the laboratory for personnel, instructions, procedures, calibration etc. and it satisfied us.
Just now we have one client who is asking that we had to made these test at accredited laboratory according to ISO 17025!
Would like to ask, could somebody tells more about this issue, also providing standard or other source!
Thanks in advance!
