We have an ISO17025 vendor that calibrates our pipettes. We are currently wanting to change our acceptance tolerance to model ISO 8655 tolerances.
The 17025 auditor is questioning the move to use the tolerances specified in ISO8655, because they are wider than the manufacture specifications for that device. Essentially, the auditor is questioning the ISO standard.
My point is this: it is an observation that mfg. specifications should be used, but certainly not a violation of 17025, or even bad metrology, to use a tolerance other than mfg. specifications. This is even more so, given that the tolerances come from an ISO standard.
Obviously this is an issue between the AB and my vendor, until the problem becomes my problem. Essentially having the AB auditor telling me what tolerances I will use becomes my problem.
Any thoughts or opinions on this would be greatly appreciated.
