GB/T 15885-1995 Fixed resistors for use in electronic equipment Part 4: Blank detail specification: Power type fixed resistors Assessment level F
Some standard content:
GB/T15885
This standard is equivalent to the international standard TEC115-4-2/QC400202:1992 Fixed resistors for electronic equipment Part 4: Blank detailed specification: Power type fixed resistors
Evaluation level F".
The upper standards promoted by this standard are GB/T5729-94 "Fixed resistors for electronic equipment Part 1: General specification" and GB5732-85 "Fixed resistors for electronic equipment Part 4: Sectional specification: Power type fixed electrical appliances". This "General specification" and "Sectional specification" are equivalent to the international standards IEC115-1/QC:40000Q:1982 and IEC115-4/QC:400200:1982 respectively. In this way, by making our standards equivalent to international standards, we can meet the needs of international trade, technology and economic exchanges. This standard is proposed by the Ministry of Electronic Industry of the People's Republic of China. This standard is under the jurisdiction of the Standardization Research Institute of the Ministry of Electronic Industry. This standard was drafted by: Standardization Institute of the Ministry of Electrical Industry. The main drafter of this standard: Liu Kuan.

IEC Foreword
1) The formal resolutions or agreements of IEC (International Electrotechnical Commission) on technical issues are formulated by technical committees participated by national committees with special concerns about these issues, and represent the international consensus on the issues involved as much as possible. 2) These resolutions or agreements are used internationally in the form of recommended standards and are recognized by national committees in this sense. 3) In order to promote international unification, IEC hopes that national committees will adopt IEC standard texts as their national standards if their national conditions permit. The differences between IEC standards and corresponding national standards should be indicated in national standards as much as possible. Foreword
This standard was formulated by IEC Technical Committee No. 40 (Capacitors and resistors for electronic equipment). The text of this standard is based on the following documents: "Six-month method\Document

Blank Detailed Specification
A blank detailed specification is a supplementary document to a sectional specification and contains requirements for the format, arrangement and minimum content of a detailed specification. Detailed specifications which do not comply with these requirements shall not be considered to be IEC specifications nor shall they be referred to as IEC specifications. The contents of 1.4 of the sectional specification shall be considered when preparing the detailed specification. The following corresponding information shall be filled in the position marked with a number in brackets at the beginning: Identification of the detailed specification
(1) The International Electrotechnical Commission or national standards body authorised to prepare the detailed specification. (2) The IEC or national detailed specification number, date of publication, and other information required by the national system. (3) The IEC or national general specification number and version number. (4) The blank detailed specification number of the [EC]. Identification of resistors
(5) A brief description of the type of resistor. (6) Information on typical construction (where applicable). NOTE: When the resistor is not designed for use on printed circuit boards, this shall be clearly indicated at this position in the detailed specification. (7) An outline drawing showing the main dimensions that have an important influence on interchangeability, and/or a reference to a national or international document on the outline. Alternatively, such a drawing may be given in an appendix to the detailed specification. (8) Type of use or application and/or assessment level. Note that the assessment level (or levels) used in the detailed specification should be selected from 3.3 of the sectional specification, which means that several assessment levels can share a single detailed specification as long as the test grouping remains unchanged. (9) Standard data of key characteristics to facilitate comparison between various types of resistors. Approved by the State Technical Supervision Commission on December 22, 1995 and implemented on August 1, 1996
