IEC 63171-2021 pdf free download – Connectors for electrical and electronic equipment – Shielded or unshielded free and fixed connectors for balanced single-pair data transmission with current-carrying capacity – General requirements and tests.
Whenever the equation results in a value greater than 84 dB, the requirement shall revert to84 dB.
The PS AFEXT requirements are fulfilled when coupling attenuation are verified.
Shielded connectors passing the requirements of transfer impedance, coupling attenuation andunbalance attenuation meet PS AFEXT by design.
NOTE Power sum alien (exogenous)NEXT cannot be determined by a mated connector in isolation. Connectorcompliance is achieved by assessing a connector’s performance when mounted in accordance with themanufacturer’s installation instructions for each mounting type assessed and in relation to all other significantconnectors in close proximity (see lEC 60512-25-9).

6 Tests and test schedule
6.1 General
This document states the test sequence (in accordance with this document) and the number of specimens for each test sequence.
Individual variants may be submitted to type tests for approval of those particular variants.
It is permissible to limit the number of variants tested to a selection representative of the whole range for which approval is required (which may be less than the range covered by the detail specification), but each feature and characteristic shall be validated against the dimensional requirements and test sequence specified in this document. The connector shall be prepared in a careful workmanlike manner, in accordance with current best practice. Unless otherwise specified, mated sets of connectors shall be tested. For contact resistance measurements, care shall be taken to keep a particular combination of connectors together during the complete test sequence; that is, when unmating is necessary for a certain test, the same connectors shall be mated for subsequent tests. Wiring of these connectors shall take into account the wire and cable diameter of the cables defined in IEC 61 1 56 (all parts) as applicable to the manufacturer’s specification.
The test shall be carried out in accordance with IEC 6051 2-2-1 , test 2a. The input to output DC resistance shall be measured between measuring points A and D for free connectors or A and C for fixed and free connectors, as shown in Figure 5.IEC 63171 pdf download.
