Introduction

Fixed capacitors for electronic equipment are basic components widely used in the electronic information industry. The development of this series of documents can guide the industry to More effectively solve the product quality evaluation problem of fixed capacitors used in electronic equipment. There are many categories or models of fixed capacitors for electronic equipment. The corresponding IEC 60384 series documents are divided into different parts. The writing method is consistent with that of IEC standards. In addition, the technical requirements for fixed capacitors of different categories or models are also different. The different parts are compiled. GB/T 6346 "Fixed Capacitors" series of documents consists of general specifications, sub-specifications, blank detailed specifications, detailed specification hierarchical system documents. See Figure 1.GB/T 6346 "Fixed Capacitors" series of documents is planned to consist of the following 48 parts (current GB/T 6346 composition documents See the preface for details). --- Part 1.General specification. The purpose is to determine the most common items of fixed capacitors for electronic equipment. Language, inspection procedures and test methods. --- Part 2 to Part 26.Sectional specifications. Sectional specifications are subordinate specifications of the general specification. Their purpose is to determine the requirements that require individual provisions. Terms and definitions, preferred ratings and characteristics of fixed capacitors for specific classes or types, and selection of applicable ones from the general specification Quality assessment procedures, test and measurement methods and additional details, as well as giving general performance requirements. These items are usually dimensions and Priority values of properties, additional test methods and relevant provisions of the test methods given in the general specification, requirements for sampling and specimen preparation, Recommended test severity levels and preferred acceptance criteria. The sectional specification also defines the test list used in all lower-level detailed specifications. The structure and scope of the table. --- Part 2-1 to Part 26-1.Blank detail specifications. The purpose is to identify the characteristics of different assessment levels that need to be specified individually. The detailed specification format, layout and minimum content requirements for fixed capacitors of certain categories or models provide specification writers with A guide for the preparation of detailed specifications that meet the requirements of the upper-level general specifications or sub-specifications. It is used to ensure the uniformity of detailed specifications. Regulation. ---Detailed specification. The purpose is to determine all the information required for a given model and range of fixed capacitors, including all specifications and dimensions. The requirements for the size and characteristic values of fixed capacitors are also given in the appropriate quality assessment system. All the information required for the determination of the test severity level and acceptance criteria for all applications and a complete test schedule. Detailed specifications can be either specifications within the national standard system or industry specifications related to the national standard system, or It is a specification established by the manufacturer or user. General Specifications This general specification covers most of the common items in the category of fixed capacitors for electronic equipment, such as terminology, measurement and test methods. The item needs to specify the conditions or parameter characteristics of a specific category or model of fixed capacitors. Such a specification requires a subsidiary under the lower level The specifications are given. For the range of fixed capacitors, the number reference for the general specification is GB/T 6346.1/IEC 60384-1. Sub-specifications The sectional specifications cover the supplement of all items given in the general specification, these are deta......
