GB/T 14598.12-1998 Electrical relays Part 19: Blank detail specification for electromechanical relays with quality assessment, all-or-nothing test schedules 1, 2 and 3
Some standard content:
GB/T14598.12-1998
This standard is formulated based on the International Electrotechnical Commission standard IEC255-19-1:1983 "Electrical relays Part 19: Blank detail specification: Tests for electromechanical relays with or without quality assessment - List 1, 2 and 3", and is equivalent to it in terms of technical content and writing rules. In this way, the blank detailed specification for quality assessment of electromechanical relays with or without quality assessment in my country is consistent with the corresponding specifications of the International Electrotechnical Commission Electronic Components Quality Assessment System (IECQ) to meet the needs of quality certification, international trade, technology and economic exchanges as soon as possible. According to GB/T1.1-1993 "Guidelines for Standardization Work Unit 1: Rules for Drafting and Presentation of Standards Part 1: Basic Regulations for the Preparation of Standards", when IEC255-19-1:1983 was converted into this standard, the 94th Technical Committee Secretariat of the International Electrotechnical Commission issued a revised version of IEC255-19-1:1983 in Document 94 (Secretariat) No. 6 (94/19/CDV). Therefore, when formulating this standard, the technical content was also modified accordingly, mainly making the following changes: In Tables I to V, the original referenced clause numbers in IEC255-7:1978 were changed to the clause numbers in IEC255-7:1991, and the technical content was also changed and supplemented accordingly. This standard was proposed by the Ministry of Electronics Industry of the People's Republic of China. This standard is under the jurisdiction of the National Technical Committee for Standardization of Electrical Relays. The drafting unit of this standard: Standardization Research Institute of the Ministry of Electronics Industry. The main drafters of this standard: Shi Xinyuan and Liu Jianbai. 256
GB/T 14598. 12--1998
IEC Foreword
1) Formal resolutions or agreements of the IEC (International Electrotechnical Commission) on technical issues are developed by technical committees in which national committees with special concerns about these issues participate, and represent the international consensus on the issues involved as far as possible. 2) These resolutions or agreements are provided for international use in the form of recommended standards and are recognized by the national committees in this sense. 3) In order to promote international unification, the IEC hopes that the national committees will adopt the text of the IEC standard as their national standard if the conditions in their country permit. The differences between the IEC standard and the corresponding national standard should be indicated in the national standard as far as possible. IEC Foreword
This standard was developed by Subcommittee 41A (with or without relays) of IEC Technical Committee 41 (Electrical Relays). The draft standard was discussed at the Helsinki meeting in 1979. After the meeting, the draft standard text 41A (Central Office) 16 was submitted to the national committees in October 1981 for approval according to the 6-month method. The following national committees voted to explicitly support this standard: Australia, Belgium, Bulgaria, Canada, China, Czechoslovakia, Egypt, France, Germany, Ireland, Italy, Japan, the Netherlands, Poland, South Africa, Sweden, Switzerland, the United Kingdom, Yugoslavia. The QC number on the cover of this standard is the specification number of IECQ (International Electrotechnical Commission Electronic Component Quality Assessment System). Technical Committee 41 has decided to classify the standard system levels as follows: First level: general standards,
Second level: general standards that apply in whole or in part to a certain type of relay; Third level: standards that apply in whole or in part to a specific sub-category of relays; Fourth level: specific requirements or specifications applicable to a specific model of relay. This standard is a fourth-level standard.

This blank detail specification specifies the test schedules 1, 2 and 3 for electromechanical all-or-nothing relays with assessed quality. 2 Purpose
This blank detail specification gives the test items to be adopted and the arrangement method to be followed when formulating the detailed specification of electromechanical all-or-nothing relays. The three test lists of this relay and their relationship are specified in the sub-specification GB/T14598.11 (IEC255-19), and GB/T14598.11 (IEC255-19) selects applicable test items from GB/T10232 (IEC255-7) according to the provisions of GB/T16608 (IEC255-10).

Any document that needs to be directly cited and is not cited elsewhere. 4 Different detailed specifications
The same detailed specification only applies to relays with similar structures. See GB/T14598.11-1997 (IEC255-19)]. 5 Marking of detailed specifications
Each detailed specification shall include the IEC number, the date of publication and the test list specified in GB/T16608 (IEC255-10) adopted.
6 Test list in detailed specifications
Each test list shall at least include the test items marked with mandatory (M) in the second part of this specification, which takes into account the relevant relay characteristics, its contact application category and Appendix B of GB/T16608-1996 (IEC255~10) and GB/T14598.11--1997 (IEC255-19) Appendix A. The test methods can be expanded and test items marked with recommendation (R) can be added. Test items not listed in Appendix B of GB/T16608-1996 (IEC255-10) can also be added. These test items can be selected from GB/T10232-1994 (IEC255-7) or outside GB/T10232-1994 (IEC255-7). When necessary, these test items can be changed according to the conditions specified in Chapters 7 and 8. For relays that meet the detailed specifications, all test items or test methods listed in the detailed specifications are mandatory. 7 Ununified test methods
At the discretion of the national committee or other standard issuing agency, tests other than those specified in GB/T10232-1994 (IEC255-7) can be included in the detailed specifications. Such test items shall be clearly indicated as non-standardized items, and their description and arrangement shall comply with the provisions of the standardized test items. 8 Modified test methods
If the technical requirements for inspection in GB/T 10232-1994 (IEC 255-7) are not completely suitable for the relays specified in the detailed specification (either due to technical reasons or due to special applications), the detailed specification shall clearly list the various changes made to these requirements.
9 Quality consistency inspection
The test lists 1, 2 and 3 applicable to quality consistency inspection are included in Tables I, III and V respectively. The order of the test items in the various groups of these tables shall be suitable for the order in which they are actually performed, but the detailed specification shall specify a mandatory order suitable for the characteristics of the relay to be tested. The test items added to the items listed in Tables I, III and V shall be arranged in appropriate groups and subgroups and shall be placed in appropriate positions in these subgroups.
When selecting the IL and AQL markings, the IL value given in front of each group should be used, and the AQL value should be within the range given.
10 Approval test
When Method 1 in Chapter 4 of GB/T16608--1996 (IEC255-10) is applicable, the test list should be as shown in Tables Ⅱ, N and V of this specification, and should be consistent with the test list used for quality consistency inspection. The sample size and the corresponding allowable number of non-conforming products should also be specified in the detailed specification. The minimum sample size is marked in the items of Tables Ⅱ, IV and И. This is because the confidence in the results of the approval test cannot be derived only from statistical principles, but also takes into account all the technical data and costs included in each test item. Each test group is the minimum sample size of 5 samples plus 1 sample (this sample is used to replace 1 unqualified relay, that is, 1 unqualified relay is allowed to appear). In most cases, the sample group composed of this may be appropriate, and all samples should be subjected to the basic test items listed in the table without failure. For example, in Table I, the test of "all samples" will require 18 samples, and 5 plus 1 samples are allocated in each of the three sample groups. If this minimum sample size is considered insufficient, the sampling plan in IEC410 should be used as a priority. In order to reach a consensus between the manufacturer and the ordering party, the limit quality of the sampling plan should be considered. Other relationships between the sample size for identification and approval inspection and the number of unqualified products allowed and the relationship between the quality consistency inspection criteria can be considered and specified in the detailed specifications.
