IEC 60512-1-2018 pdf free.Connectors for electrical and electronic equipment -Tests and measurements -Part 1: Generic specification.
This part of lEC 60512 is intended to be used as a basis for tests and measurementsspecifications for electrical connectors. It provides guidance and reference for tests andmeasurements within the lEC 60512 series.
lt includes the description and the practice of the various phases of tests and measurements(preparation， tests and measurements，requirements，documentation),in addition to basicterms and definitions applicable to any part of the lEC 60512 series.
This document is used in conjunction with IEC 60512-1-101 to establish uniform detail testsand measurements specifications.
Detail tests and measurements specifications are applicable to electrical connectors and theircomponents (e.g.connector inserts， connector housings，locking mechanisms，contacts andterminations)within the scope of technical committee 48.They may also be used for similardevices when specified in a detail product specification.
Detail tests and measurements specifications are used in conjunction with detail productspecifications which prescribe the tests to be used, the required degree of severity for each ofthem and the permissible performance limits.The detail product specification also specifiesthe deviations in procedures,which may be required when applying a test to the type ofconnector or its component under consideration，and it further specifies any specialprocedures which may be required.
NOTE RF and fibre optical connectors are not dealt with by subcommittee 48B, however, hybrid connectors whichadditionally employ RF and/or fibre optic contacts, are handled by SC 48B in cooperation with TC 46 and/orTC 86.

3.1 ambient temperature temperature of the air in free air conditions at such a distance from the specimen that theeffect of the dissipation is negligible.
Note 1 to entry: ln practice，the ambient temperature is taken as the average of temperatures measured at anumber of points in a horizontal plane situated between 0 mm and 50 mm below the specimen at half the distancebetween the specimen and the wall of the chamber, or at 1 m distance from the specimen，whichever is less.Suitable precautions should be taken to avoid heat radiation affecting these measurements.[SoURCE: IEC 60068-1: 2013,3.9.2]
3.2 combined test test during which a specimen is subjected simultaneously to two or more environmental influences.
Note 1 to entry: Tests with simultaneous influence of a) temperature and humidity; b) temperature, humidity andspecific(including chemically active) medium; and c) temperature and solar radiation are not related to combinedtests.
Note 2 to entry: Combined tests, as a rule, are used to provide simultaneous climatic and mechanical influences.IEC 60512-1 pdf download.
