Guidance for determination of clearances,creepage distances and
requirements for solid insulation for equipment with a rated voltage
above 1 000 V AC and 1 500 V DC,and up to 2 000 V AC and 3 000 V DC.
Standard in brief
Scope of Application：
This document serves as a technical specification to provide guidance to technical committees for the determination of insulation fits for equipment with rated voltages from 1 000 V to 2 000 V ac and from 1 500 V to 3 000 V dc. For equipment with rated voltages up to 1 000 V AC and 1 500 V DC and with higher or lower internal voltages for insulation fits, the relevant requirements are given in IEC 60664 1. This document applies to equipment for use at altitudes up to 2 000 m above sea level and provides guidance for use at higher altitudes. This document specifies guidelines for electrical clearances, creepage distances and solid insulation for equipment to meet safety requirements, including relevant electrical test methods. NOTE: Since the requirements for functional insulation are not part of the safety requirements, they are not specified accordingly. This document is not concerned with determining the following types of distances: - insulation through liquids; - through gases other than air; - through compressed air.
