Re: Does ISO/IEC 17025 supercede ANSI/NCSL Z540
This is a very confusing issue to me.
A few years ago, someone from the ANSI organization told me in writing that the Z540.1 was superceded by the Z540.3.
Yet, our AB says no- Z540.3 is a completely different set of requirement:
There is some misunderstanding in the industry regarding this standard. The Z540.3 is NOT simply a newer revision of the Z540.1, it is a whole different set of requirements. Specifically relating to a 17025 accredited calibration lab, there is only paragraph 5.3 of the Z540.3. The rest of the standard applies to the customer (end user) of the data we would provide. Most customers are unaware that the Z540.3 actually requires them to perform additional work / analysis of the requirements provided this standard. Note that paragraph 5.3 states ?Calibration-servicing components may be considered competent to provide calibration services when they have been accredited to meet ANSI/ISO/IEC 17025?, which of course is what we are accredited to.
We still reference and use Z540.1 on certifications and treat it as a valid document.
