Title Space product assurance - Wire-wrapping of high-reliability electrical connections
Project Number 15131
Abstract/Scope This standard specifies the methods for preparing and assembling the parts to be joined by wire wrapping, and the selection, calibration, use and certification of the wire wrapping tools. The required wire­wrapped connections are illustrated in Figure 1. This type of connection is similar to “Class A preferred” or “modified” connection detailed in MIL STD 1130, and NASA NHB 5300.4(3H). Only tested and qualified wire­wrapped connections are covered by this standard, which lists four wire sizes from 24 AWG to 30 AWG, and three terminal post sizes up to 1,78 mm maximum diagonal. The use of thicker wire and larger terminals are not advised. Thicker wire than 24 AWG is generally multistranded and terminated by soldering (see ECSS Q 70 08) or by crimping (see ECSS Q 70 26). Training and certification requirements for operators and inspectors are defined in 9.7 and in EN 13291 1.

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved


(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat


(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level


(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement


(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
