This standard is equivalent to the industrial standard JIS C2336-1991 "Pressure Sensitive Polyvinyl Chloride Adhesive Tapes for Electrical Insulation". The main difference between this standard and JIS C2336-1991 is that the inspection rules for products are detailed according to the actual situation in my country. This standard was proposed by the Technical Supervision Department of the former Ministry of Chemical Industry of the People's Republic of China. This standard is under the jurisdiction of the National Adhesive Standardization Technical Committee. The drafting unit of this standard: Shanghai Rubber Products Research Institute. The main drafters of this standard: Ju Yinhan and Chen Xiufen. This standard is entrusted to the National Adhesive Standardization Technical Committee for interpretation. 1 Scope
Chemical Industry Standard of the People's Republic of China
Polyvinyl chloride pressure-sensitive adhesive tapes for electrical insulation Pressure Sensitive Polyvinyl Chloride Adhesive Tapes for Electrical Insulation HG/T 3596—1999
This standard specifies the technical requirements, test force method, inspection rules, packaging, marking, transportation and storage of polyvinyl chloride pressure-sensitive adhesive tapes for electrical insulation.
This standard is applicable to pressure-sensitive adhesive tapes with polyvinyl chloride film as the base material and adhesive coated evenly on one side. It is mainly used for electrical insulation.
