Together with every accreditation there is a list for which the accreditation is valid, or with other words which measurements can be performed accredited. This list is called the scope of accreditation. STRI is accredited for both High-Voltage Testing and High-Voltage Calibration.
In general, STRI is accredited for AC, DC, LI, SI, Temperature Rise testing, measurement of RIV (Radio Interference Voltage), PD (Partial Discharge) and Capacitance tan delta. Further STRI is accredited for AC, DC, LI and SI calibrations.
