This standard specifies the classification, technical requirements, test methods, inspection rules, marking, and packaging of insulating materials for pipes and rods used in live working. This standard is applicable to hollow insulating pipes, foam filled insulating pipes and solid insulating rods (profiled pipes and expansion pipes are not included in this standard) used for making live working tools and equipment in power systems with nominal voltages of 1kV and above. These insulating materials are made of synthetic materials 2 Normative References: The clauses in the following documents become the clauses of this standard through the reference surface of this standard.
