Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. This standard replaces GB/T 4596-1984 "electronic device with three-phase transformer E-shaped core." This standard compared with GB/T 4596-1984, the main changes are as follows. a) an increase of some chapters of the title; b) a reference to the file version specified redefined references, the latest version of the file, and adds a reference to the GB/T 2829 "Week Sampling of inspection procedures and tables (suitable for process stability test) "; c) on the "6 Acceptance Rules" chapter require more explicit; 1) "core factory delivery shall be subject to technical inspection department inspection" to "core factory delivery shall be subject to quality inspection department Doors batch testing and periodic inspection "(see 61, 1984, version 4.1.); 2) "when running tests on each batch of core settlement shall be 100% according to the provisions of the order 3.2 and 3.3 were tested. Settlement GB 2828-81 test can also be predetermined sampling inspection, then the provisions relating to consultation by both parties really When set "to" test batches, each batch of core settlement shall be 100% of the predetermined order of 5.3 and 5.4 trial Experience. Batch testing can also be GB/T 2828.1 standard, a sampling program, the general inspection level Ⅱ and the relevant provisions into Line "(see 62, 1984 version 4.3.); 3) "routine test" to "test period" (see 63, 1984 version 4.5 to 4.7).; 4) "routine tests at the manufacturer's technical inspection department once a year. When changing the raw materials and manufacturing processes must also enter Line routine tests "to" when one of the following conditions, periodic inspection should be carried out. " --- New products or old products to the plant production trial identification; --- Such as formal structure, materials, production processes are greatly changed, it may affect product performance; --- When normal production every six months (except life test); --- Resume production after the long shutdown when the product; When there are large differences --- batch test results the last inspection cycle; --- When the national supervisory bodies conduct periodic inspection requirements (see 6.3 1, 1984 edition 4.5). The standard proposed by the Ministry of Industry and Information Technology of the People's Republic of China. This standard by the national magnetic components and ferrite materials Standardization Technical Committee (SAC/TC89) centralized. This standard was drafted. Device Technology Co., Ltd. Sichuan Changhong. The main drafters of this standard. Zhu Wei, Wang Qingdong, Yang Tao. This standard replaces the standards previously issued as follows. --- GB/T 4596-1984. Electronic equipment with three-phase transformer E-shaped core
