8、fication. Measurements shall be carried out on elements of connection which are mated or unmated in accordance with the technical specification. Unless otherwise specified in the test concerned, the specimens shall not be cleaned. 3.2 Unless indicated in the technical specification, the following de

9、tails shall be specified : - measuring method (A, B or C) to be used, - elements of connection mated or unmated, - minimum value of the insulation resistance specified by the test concerned, e.g. environmental , contamination, temperature, moisture tests, etc. 4 Methods + 20 The insulation resistanc

10、e shall be measured under (500 o 1 V d.c. The insulation resistance shall be recorded when a stable reading is obtained. If a stable cond+i&on is not reached, the insulation resistance reading shall be recorded within (60 o) s after application of test voltage. 4.1 Method A The insulation resistance

11、 shall be measured in turn between each contact and all the others connected together and to the housing (shell) or the mounting plate. 4.2 Method 3 Alternate contacts shall be connected together to form two groups, the first group including all even numbered contacts, the other all odd numbered con

13、1-B6 Page 4 The insulation resistance shall be measured in turn between : - the first group of contacts and the second group connected to the housing (shell) or to the mounting plate, - the second group of contacts and the first group connected to the housing (shell) or to tt ie mounting plate. In t

14、he case of contacts arranged in two or more rows, it may be necessary to form a second arrangement of two groups in order to measure the insulation resistance between all adjacent contacts. 4.3 Method C ThG insulation resistance shall be measured between two adjacent contacts or one contact and the
