scope:

This specification sets forth accepted methods for testing and reporting the performance characteristics of Rogowski-type air core Current Sensing Coils (CSCs)and the Weld Current Monitors (WCMs) used in the measurement of secondary current in single-phase a resistance welding. CSCs mounted inside transformers are not included in this specification. Traceability of measurements to National Standards as required by this specification is discussed. References regarding traceability concepts and requirements are provided. Sources of measurement uncertainty, methods of combining these uncertainties, and the manner in which the overall uncertainty is to be stated are discussed. This standard makes sole use of SI units. Safety and health issues and concerns are beyond the scope of this standard and therefore are not addressed herein. Safety and health information is available from other sources, including, but not limited to, applicable federal and state regulations.
