31、C 61810 states the test and measurement procedures for electromechanical elementary relays. It covers basic considerations which are, in general, common to all types of electromechanical elementary relays. Supplementary requirements may be necessitated by specific designs or application. The test an
32、d measurement procedures of this standard are described as individual provisions covering a specific requirement. When combining them in a test programme, care must be taken (for example by suitable grouping of tested relays) to ensure that preceding tests do not devalue subsequent ones. Where in th
33、is standard the term “specified” is used, this means a prescription in the appropriate documentation for the relay, for example manufacturers data sheet, test specification, customer detail specification. For application within the IECQ system such prescriptions are contained in the detail specifica
34、tion as defined in Clause A.7 of QC 001001. NOTE 1 To improve the readability of this standard, the term “relay” is generally used in place of “electromechanical elementary relay”. NOTE 2 Requirements and tests related to the type testing of electromechanical elementary relays are contained in IEC 6
35、1810-1. For that purpose, the generally described test and measurement procedures of this standard have been prescribed in a more restricted and stringent form in IEC 61810-1. NOTE 3 Standards covering relays subjected to quality assessment in accordance with IECQ are compiled in the IEC 61811 serie
