This standard (EN 16602-70

33、-30:2014) originates from ECSS-Q-ST-70-30C. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by April 2015, and conflicting national standards shall be withdrawn at the latest by April 2015. Attention

34、 is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 50389:2005. This document has been prepared under a mandate given t

35、o CEN by the European Commission and the European Free Trade Association. This document has been developed to cover specifically space systems and has therefore precedence over any EN covering the same scope but with a wider domain of applicability (e.g. : aerospace). According to the CEN-CENELEC In

36、ternal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland,

37、 Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. DIN EN 16602-70-30:2015-07 EN 16602-70-30:2014 (E) 6 1 Scope This Standard specifies requirements for preparing and as

38、sembling parts to be joined by wire wrapping, as well as the selection, calibration, use and certification of wire wrapping tools. The covered wire-wrapped connections are illustrated in Figure 1-1. This type of connection is similar to “Class A preferred” or “modified” connection detailed in MIL-ST

39、D-1130, and NASA NHB 5300.4(3H). Only previously tested and qualified wire-wrapped 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 Anne

40、x 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 wire-wrapping would be chosen as the electrical interconnection technique. Instead it is assumed that wire larger than 24 AWG will be multi-strand

41、ed 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

42、 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. DIN EN 16602-70-30:2015-07 EN 1
