|Publication Date:||1 October 2005|
|ICS Code (Welding processes):||25.160.10|
This part of ISO 17657 specifies calibration systems and calibration procedures for welding current measuring systems, current sensors, welding current meters and monitoring devices with current sensor used for measuring welding current in resistance welding with alternating current of 50 Hz or 60 Hz, or with direct current. The procedures are applicable for a current range between 0,5 kA and 25 kA.
