National Standard of the P.R.C., Safety requirements for resistance welding machine; (60 page(s), in Chinese)

This document applies to equipment for resistance welding and allied processes and includes single and multiple welding stations which may be manually or automatically loaded and/or started.

This document also applies to stationary and portable equipment.

This document specifies the eletrical safety requirements for resistance welding machine in design, manufacture, and installation. It does not cover all non-electrical safety requirements (e.g. noise, vibration).

This document does not include electromagnetic compatibility (EMC) requirements, which are specified in GB/T 31251.2-2014. To comply with this document, all safety risks associated with resistance welding machine during loading, feeding, operating and unloading the equipment, where applicable, shell be assessed and the requirements of related standards shell be observed.
