Foreword

This standard integration and replaces GB/T 12913-1991 "capacitor paper", GB/T 14217-1993 "paper-capacitor dissipation factor (Tgdelta) Determination ", GB/T 12656-1990" frequency breakdown voltage capacitor paper determination "and GB/T 12657-1990" capacitor paper guide Isoelectric point determination. " This standard and GB/T 12913-1991, GB/T 14217-1993, GB/T 12656-1990 and GB/T 12657-1990 phase Ratio, the main changes are as follows: Etc.

--- level of quality from the original, etc. A, B and C and so on to superior products, first-class goods and qualified products;

--- Modified I and II capacitor paper defined and according to market demand, the type II capacitor paper thicknesses range from the original 4µm ~ 17µm expanded to 4µm ~ 22µm;

--- The type I series 1.15g/cm3 tightness series shifted type II series;

--- The type II series tightness of 1.22g/cm3 was changed to 1.20g/cm3;

--- Improve water soluble chloride index;

--- Improving the ash indicators;

--- Modified capacitor paper size specifications;

--- Modify the number of joints capacitor paper;

--- Revised delivery inspection sampling program;

--- Modify the product identification method;

--- Modified capacitor paper and packaging requirements;

--- Due to improved measuring device, the determination of appropriate adjustments to the paper medium capacitor loss factor. The Standard Appendix A, Appendix B, Appendix C are normative appendix. The standard proposed by China National Light Industry Council. This standard by the National Standardization Technical Committee of the paper industry. This standard was drafted. Minfeng Special Paper Co., Nine Dragons Paper Pulp (Leshan) Co., Ltd., China Pulp and Paper Research Institute. The main drafters of this standard. Hai-Ning Liu, Zhu Xiaohong, Zhang Jianping, Wang early beads. This standard replaces the standards previously issued as follows:

--- QB603-1981, GB/T 12913-1991;

1 Scope

GB/T 12913-2008 is the Chinese national standard on capacitor tissue paper, in the field of paper technology. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 19 August 2008 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 May 2009. Classification: ICS 85.060, CCS Y32. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the capacitor paper product classifications, technical requirements, test methods, inspection rules, marking, packaging, transportation and storage. This standard applies to do metallized paper dielectric capacitors and standard capacitor paper.
