Electrical, electronic and programmable electronic control systems of machine tools - Specification of the continuity of the protective bonding circuit test
This standard specifies terminologies and definitions, test equipment, test conditions, test methods and test records of electrical, electronic and programmable electronic control systems of machine tools - protective bonding circuit continuity test.
This standard is applicable to continuity test on protective bonding circuit of electrical, electronic and programmable electronic control systems of machine tools (hereafter referred to as "electrical system" collectively) with nominal voltage not exceeding AC 1,000 V or DC 1,500V and rated frequency not exceeding 200 Hz; as for continuity test on protective bonding circuit of mechanical electrical system similar to machine tools, this standard may be referred to.
Note 1: Machine tools refer to metal-cutting machine tool, electrical process machine and other types of machine tools;
Note 2: Electrical, electronic and programmable electronic control systems of machine tools respectively refer to machine tool electrical system, electronic system and programmable electronic control system. Electronic system and programmable electronic control system used in machine tool electrical system are part of the machine tool electrical system and not independent systems.
