Luke et al Are you trying to satisfy the relevant clauses of ISO 17025 "General requirements for the competence of testing and calibration laboratories" ? I have been following the guidance in UKAS document LAB 34 http://www.ukas.com/pdfs/Lab34.pdf for calculating uncertainties in EMC measurements. This is based on the older NIS 81 document and references the CISPR standard you refer to. Am I correct in saying that as long as you do a valid assessment of uncertainties, by following whatever standard, you can satisfy the relevant requirements of ISO 17025?
On the issue of verification of ESD test equipment, referred to in other postings, but relevant to ISO 17025 compliance, is it not sufficient to merely observe that a spark is generated by a calibrated ESD gun when the device is operational and brought close to a conductive surface? Do you really need to observe the waveform? If this is not sufficient then shouldn't the same rationale be applied to all other pieces of immunity test equipment?
