5、ntacts 11 Page 3 TR 4680:10-05 Foreword The main task of ASD-STAN is to prepare EN standards. In exceptional circumstances, however, the publication of a Technical Report of one of the following types may be proposed: type 1, the subject is still under technical development requiring wider exposure;

6、 type 2, a Technical Domain has collected data of a different kind from that which is normally published as a European Standard. The Electrical Domain decided to publish this document in the form of a Technical Report of type 2, as it contains only general guidelines. Technical Reports are normally

7、published in a trilingual version. Due to the volume of this document, the report is published, as an exception, in three separate language versions. Page 4 TR 4680:10-05 1 Scope This Technical Report is a guideline for the mandated body and the manufacturer to establish a programme of qualification

10、ests 4.1 General Programmes of qualification tests are test groups defined per kind of change in design of contacts for each EN standard. They precise the sequence tests and the availability test per EN standard. The test severities and the initial and final measurement shall be in agreement with th

11、e qualification tests in the EN Standard concerned. 4.2 Sampling and definition of specimens The specimens shall be representative of the kind of change in design of contacts and the sampling equivalent to the number in the qualification groups. 4.3 List of tests See Table 1.
