35、ules lugs and splices. NOTE These are the most common used crimping wire termination and are represented in Figure 1-1. The general conditions to be met for the approval of terminations other than the above mentioned ones. NOTE Additional forms of crimps, not covered in this standard, are listed (no
36、t exhaustively) in the informative Annex A. Product assurance provisions for both the specific and the generic terminations mentioned above. Training and certification requirements for operators and inspectors (clause 5.5.2), additional to those specified in ECSS-Q-ST-20. This standard may be tailor
37、ed for the specific characteristics and constraints of a space project, in conformance with ECSS-S-ST-00.
