EN 16602-70-30 Space product assurance - Wire wrapping of high-reliability electrical connections - This Standard specifies requirements for preparing and assembling parts to be joined by wire wrapping, as well as the selection, calibration, use and certification of wire wrapping tools. The covered wire­wrapped connections are illustrated in Figure 1 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 previously tested and qualified wire­wrapped connections are covered by this Standard, which includes four wire sizes from 24 AWG to 30 AWG, and three terminal post sizes up to 1,78 mm maximum diagonal. A step-by step procedure is covered in the informative Annex A. The use of heavier gauge wire and larger terminals is not generally prohibited, but it is considered unlikely that for such dimensions the method of wire­wrapping would be chosen as the electrical interconnection technique. Instead it is assumed that wire larger than 24 AWG will be multi-stranded and terminated by soldering in conformance with ECSS-Q-ST-70-08, or by crimping in conformance with ECSS-Q-ST-70-26. Training and certification requirements for operators and inspectors are defined in clause 5.6.7 and in ECSS-Q-ST-20. With effect from the date of approval, this Standard announces the adoption of the external document on a restricted basis for use in the European Cooperation for Space Standardization (ECSS) system. This standard may be tailored for the specific characteristic and constraints of a space project in conformance with ECSS-S-ST-00.
