12、ble from and replaceable in the connector. A specific terminus may be used in a wide variety of connector styles (0.g. circular, rectangular, rack and panel, hybrid, etc.) which may be qualified under other specification systems (e.g. specifications for electrical connectors). 1.3.2 termlnus set: Th
13、e two mateable termini. Generally, a set consists of a terminus pin and a terminus socket. 1.3.3 mechanically intermateable termlni: Termini which are capable of being mechani- cally mated. Performance or intermountability are not requirements for intermateability. - E II - - - 1.3.4 Interchangeable
14、 terminl: Termini which meet the same assessed performance specification and are intermountable. Interchangeability applies to a terminus set only * m since individual termini are not necessarily intermateable. 1.3.5 intermountable terminl: Termini which have identical mounting parameters. Intermate
15、ability or interchangeability are not requirements for intermountability. 1.3.6 termlnl control dlmenslons: Those termini dimensions which control inter- mateability and intermountability. 1.4 Abbreviations NSI: National Supervising Inspectorate; QPL: Qualified Products List. 2 Requirements 2.1 Qual
