QB/T 2192—1996
This standard is equivalent to the International Electrotechnical Commission standard IEC554-3-1 (first edition, 1979) "Specifications for fiber paper for electrical use, Part 3: Single material Part 1: General purpose electrical paper". The formulation of this standard changes the technical requirements of the former Ministry of Light Industry standard QB332—1982 "Wound insulation paper" to change the tightness to thickness and the tension to tensile strength. The inspection rules adopt GB/T2828 "Batch inspection counting sampling procedures and sampling tables (applicable to continuous batch inspection)", and the test conditions adopt the new atmospheric conditions of (23±1)℃ and (50±2)%rh. This standard was proposed by the Food Papermaking Department of the China Light Industry Association. This standard is under the jurisdiction of the National Papermaking Standardization Center. The drafting unit of this standard: Jinan Dayi Papermaking Co., Ltd. Fourth Factory. The main drafters of this standard: Chen Qi, Gao Baiquan, Zhang Zhen, Chen Shuo. This standard was first published in 1968.
This standard was first revised in May 1982.
