Aerospace series - Connectors, electrical, circular, bayonet coupling, operating temperature 175 °C or 200 °C continuous - Part 001: Technical specification; German and English version EN 3646-001:2015
Luft- und Raumfahrt - Elektrische Rundsteckverbinder mit Bajonettkupplung, Betriebstemperatur 175 °C oder 200 °C konstant - Teil 001: Technische Lieferbedingungen; Deutsche und Englische Fassung EN 3646-001:2015
Overview
The DIN EN 3646 series of standards describes the properties of electrical circular connectors with bayonet coupling for aerospace applications at operating temperatures of up to 175 °C or 200 °C continuous. The new edition of Part 001 specifies the general characteristics, the conditions for qualification, acceptance and quality assurance, as well as the test programmes and groups for bayonet coupling circular connectors, intended for use in an operating temperature range of -65 °C to 175 °C or 200 °C continuous according to the class and models. This family of connectors is derived from MIL-DTL-26482, series 2, the NAS 1599 bayonet connector with which it is intermateable and which uses AS-39029 for the contacts. It is particularly suitable for use on aircraft applying EN 2282. These connectors are distinguishable from MIL-DTL-26482 and NAS 1599 by: - being of a lower mass; - having reduced dimensions; - accepting smaller cables. The following changes have been made compared to the previous edition DIN EN 3646-001:2008-04: a) the normative references have been revised; b) in Table 9 the temperature details have been exchanged in the details for test EN 2591-305; c) reference has been made to EN 3909 in the liquids in Table 10; d) the missing legends have been added in Figure 40 and Figure 41; e) protective caps have been included instead of blank specimens for test group 6 in Table 14; f) the exceptions for design Y have been changed for several tests in the qualification tests in Table 15, and the second salt spray test has been omitted in group 6. The standards of the EN 3646 series are prepared by the ASD-STAN, Technical Section Electrotechnology, with the participation of German experts from DIN Standards Committee Aerospace (NL). AeroSpace and Defence Industries Association of Europe - Standardization (ASD-STAN) has been declared responsible by the European Committee for Standardization (CEN) for preparing European Standards (EN) for the field of aerospace. ASD became the Associated Organization (ASB) of CEN by the agreement dated 3 October 1986. The responsible German standardization body is Working Committee NA 131-04-03 AA "Elektrische Verbindungselemente" ("Electrical Connectors") at DIN Standards Committee Aerospace (NL).
