Foreword
GB/T 14860 "electronic and telecommunication equipment transformers and inductors for" approval procedure is based on the ability to assess the quality of the electronic and communications equipment
Transformers and inductors standard, divided into the following seven sections.
--- Part 1. Generic specification;
--- Part 2. Evaluation of the capability approval procedure quality specification for signal transformers;
--- Part 3. Evaluation of the capability approval procedure quality specification for power transformers;
--- Part 4. Evaluation of the quality of the capability approval procedure switch specification for power transformers;
--- Part 5. Evaluation of the capability approval procedure quality specification for pulse transformers;
--- Part 6. the capability approval procedure inductors of assessed quality specification;
--- Part 7. Evaluation of the quality of the capability approval procedure of the high-frequency inductors and intermediate frequency transformers.
This is Part 4 GB/T 14860 in.
Rules in this section in accordance with GB/T 1.1-2009 given draft.
This Part replaces GB/T 15184-1994 "quality capability approval of electronic switching equipment specification for power transformers."
Compared to major changes in this part of GB/T 15184-1994 as follows.
--- Standard number has been adjusted by the GB/T 15184 changed to GB/T 14860.4;
--- Added some references, references were made in refinement and part of the standard part of the corresponding national standards
(See Chapter 2);
--- In the preparation of "detailed specification" clause, the increase in the terms of usage (see Chapter 5).
The partial modification of the use of IEC 61248-4.1996 "electronic and telecommunication equipment transformers and inductors - Part 4. the capability approval process
Order assessed quality switching power transformer specification "(in English).
For ease of use, this section of IEC 61248-4.1996 made minor modifications to modify its main content is to IEC 61248-4..
IEC 60068 environmental testing standard cited in 1996 adopted GB/T 2423 national standards instead of the corresponding country. It will also
IEC 60410. 1973 "counter check sampling plan and procedures" with the GB/T 2828.1-2003 "Sampling procedures for inspection - Part 1. Press
Acceptance quality limit (AQL) retrieval batch inspection sampling plan "instead.
For ease of use, IEC 61248-4.1996 This section also made the following editorial changes.
--- "Normative references", the guide word according to GB/T 1.1-2009 provisions;
--- References in some of the standard replaced by the use of international standards to national standards or industry standards;
--- Delete the reference file IEC 102 guidelines. 1989, IEC QC001001. 1986, IEC QC001002. 1986,
IEC QC001005 other standards;
--- The "IEC 68-2-6" to "IEC 60068-2-6";
--- Remove the IEC standard foreword.
This part is proposed by the Ministry of Industry and Information Technology of the People's Republic of China.
This part of the National Magnetic components and ferrite materials Standardization Technical Committee (SAC/TC89) centralized.
This section drafted by. Device Technology Co., Ltd. Sichuan Changhong.
The main drafters of this section. Zhu Wei, Yang Tao, Wang Qingdong.
This part of the standard replaces the previous editions are.
--- GB/T 15184-1994.
