This document specifies requirements for setting a uniform procedure to verify the effectiveness of the protective measures for current-using electrical equipment or appliances after they have been repaired. This procedure is applicable to equipment or appliances that are pluggable equipment type A connected to final circuits via a plug or permanently connected equipment, with a rated voltage above 25 V AC and 60 V DC up to 1 000 V AC and 1 500 V DC, and currents up to 63A. This standard does not cover: - type tests, routine tests and acceptance tests for product safety requirements and product functional requirements. NOTE – Product safety requirements and product functional requirements are specified in the related product standards. This document assumes that the electrical equipment under consideration complies with its related product standard, has been introduced on the market, has been in use, has failed, and has then been repaired. It intends to verify that operations for repairs have not jeopardized basic protective measures, for example to verify the continuity of the protective conductor, the withstand capability of the insulation or to verify that no metallic part is loose or is inadvertently inserted in the device. This document does not apply to: - devices and equipment that are part of the fix electrical installations. For these devices, tests for verification after repair are covered by IEC 60364 6; - audio/video, information and communication technology equipment; - uninterruptible Power Supply (UPS); - charging stations for electro-mobility; - power supplies; - programmable Logic Controllers (PLC); - power Drives; - devices for EX-zones or for mining applications in general; - products already covered by standards addressing similar topics such as: - medical equipment covered by IEC 60601 1. For these devices, tests for verification after repair are covered by IEC 62353; - arc welding equipment covered by IEC 60974 1. For these ...
