GB/T 2900. 5—2002
This standard is equivalent to IEC60050 (212): 1990 (first edition) "International Electrotechnical Vocabulary Insulating Solids, Liquids and Gases", and refers to the relevant parts of IEC60050 (151): 2001 "International Electrotechnical Vocabulary Electric and Magnetic Devices" and IEC60050 (121): 1998 "International Electrotechnical Vocabulary Electromagnetism". This standard is a revision of GB/T 2900.5-1983 "Electrical Vocabulary Terminology Electrical Insulating Materials". Compared with IFC60050(212), this standard has made the following technical adjustments: 1) According to IEC60050(151):2001, the definitions of 212-01-01 "Insulating material", 212-01-12 "Electrode", 212-01-02 "Insulating liquid", 212-01-03 "Insulating gas" have been modified; 2) According to IEC60050(121):1998, the definitions of 212-01-04 "Dielectric" have been modified. 12-01-22\Dielectric loss\, 212-01-23\[Absolute "permittivity", 212-01.24\Relative permittivity", 212-01-25\Complex relative permittivity", 212-01-26 "Real relative permittivity", 212-01-27\[Dielectric] loss index\ 212-01-30\Dielectric loss angle", 212-01-31\Effective complex relative permittivity", 212-01-33\Definition of electrical breakdown.
3) IEC60050 (121): 1998 has determined that "dielectric constant" is a deprecated term, but it is widely used in China. Therefore, after the six terms 212-01-23 "absolute permittivity", 212-01-24 "relative permittivity", 212-01-25 "complex relative permittivity", 212-01-26 "real relative permittivity", 212-01-31 "effective complex relative permittivity", and 212-01-32 "static permittivity", GB According to the provisions of GB/T1.6, "absolute dielectric constant", "relative dielectric constant", "complex relative dielectric constant", "real relative dielectric constant", "effective complex relative dielectric constant" and "static dielectric constant" are added in the form of permissible terms. According to the needs, the permissible term "fabric" is added after "212-05-12\cloth". In addition, 10 commonly used terms in China, such as "dielectric properties", "quality factor", "spark discharge", "impregnation paint", "adhesive paint", "silicon steel sheet paint", "semi-conductive paint", "laminated board", "quantitative" and "oil resistance", are added. These terms were once included in GB/T 2900. 5—1983.
4) IEC60050 (212) is composed of two standards. There are repeated terms. This standard has deleted them: "aging" is listed in 212-02-03, "accelerated aging" is listed in 212-02-04, "immersion" is listed in 212-03-01 and "antioxidant" is listed in 212-04-14. Some terms are universal, so this standard moves them forward: "additive" is listed in 212-04-09, and "passivator" is listed in 212-04-16. The definitions of the terms "catalyst", "inhibitor", "antioxidant" and "passivator" after the term "additive" have been adjusted accordingly. The term numbering has also been adjusted accordingly:
5) According to the requirements of GB/T1.11997, this standard adds the content of Chapter 1 and the title of Chapter 2. The main technical differences between this standard and GB/T2900.5-1983 are as follows: 1) Two chapters, "Scope" and "Terms and Definitions", are added according to GB/T1. 2) The standard name is added according to IEC60050 (212): 1990. 3) Since GB/T2900.5-1983 was formulated with reference to the draft of IEC60050 (212). The formal publications IEC60050 (212): 1990, IEC60050 (151): 2001 and IEC60050 (121): 1998 have made many additions and deletions to the draft in terms of technical content, this standard adopts the above international standards and revises GB/T2900.5-1983. From the date of implementation, this standard will replace GB3/T2900.5-1983. Appendix A and Appendix B of this standard are indicative appendices. This standard was proposed by the National Technical Committee for Standardization of Electrical Terminology. This standard is under the jurisdiction of the National Technical Committee for Standardization of Electrical Terms and the National Technical Committee for Standardization of Insulating Materials. The drafting units of this standard are Xi'an Jiaotong University and Guilin Electric Science Research Institute. The drafters of this standard are Cao Xiaolong, Luo Chuanyong and Cheng Songzhen. This standard was first issued on October 28, 1983. The first revision was in May 2002. This standard is entrusted to the National Technical Committee for Standardization of Electrical Terms and the National Technical Committee for Standardization of Insulating Materials for interpretation. 1

IEC Foreword
1) IEC's final resolutions or agreements on technical issues are formulated by technical committees composed of representatives of national committees that are particularly concerned about these issues, and express the international consensus on the issues studied as much as possible. 2) These technical resolutions or agreements are used internationally in the form of recommendations and are accepted by national committees in this sense. 3) In order to promote international unification, IEC hopes that national committees will adopt IEC recommended texts as their national standards within the scope of their national conditions. Any differences between IEC recommended texts and corresponding national standards should be clearly indicated in the national standards as far as possible.
IEC Introduction
This standard constitutes Chapter 212 of the International Electrotechnical Vocabulary (IFV). This standard was prepared by EC/TC10 (Electrical) under the leadership of IEC/TC1 (Terminology).This standard was jointly developed by WG1 (Working Group 1) of TC15 (Insulating Materials) and WG1 of IEC/TC 15 (Insulating Materials). This standard is based on two documents: one is Chapter 212 "Solid Insulating Materials" drafted by WG1 of TC15, and the other is Chapter 215 "Insulating Liquids and Gases" drafted by WG1 of TC10. TC1 agreed with the opinions of WG1 of TC10 and WG1 of TC15 and decided to combine Chapters 212 and 215 into one chapter (i.e. Chapter 212 of this standard), thus forming this standard. Section 212-01 contains the terms common to the documents on which Chapters 211 and 215 are based. The text of this standard is based on the following documents:

An additive added to improve the oxidation resistance of insulating materials, which can passivate gold kitchen solids or metal ions that act as oxidation catalysts.
Gel
The colloidal solid that appears initially when the resin is formed. 212-04-18 Degree of polymerization (of a polymer) The average number of basic units in a polymer molecule. Note: The same material can have different average values (number average, weight average or viscosity average). 8Weight average or viscosity average). 8Weight average or viscosity average). 85—2002
A plastic that can be softened, cooled and hardened by repeated heating within a specific temperature range. In the softening stage, molding, extrusion or forming are used to achieve flow and can be formed repeatedly. 212-04-04 Thermosetting plastic therimoset
can be transformed into a completely infusible and insoluble plastic after solidification by heating or other methods. Note: Thermosetting plastics are often called thermosetting plastics before curing and thermosetting plastics after curing. 212-04-05 Elastomer elastomer
A polymer material that can produce significant deformation with a slight stress, and can quickly and roughly return to its original size and shape after the stress is relieved.
Note: This definition applies to room temperature test conditions. 212-04-06 Latex Jatex
Colloidal aqueous dispersion of polymer material.
212-04-07 Plasticizer plasticizer
In order to reduce the softening temperature range and improve the processability, flexibility or extensibility of plastics, a very volatile substance is added to plastics Low substance.
212-04-08 Filler (in plastics) fier (inaplastic) is a relative condition added to plastics in order to improve the strength, durability, processing performance or other properties of plastics, or to reduce costs. solid material.
