22、 according to the technical specification. 3.2 Unless specified in the technical specification, the following details shall be stated: specimens mated or unmated and fitted with protective cover (if applicable); mounting method, type of cable and definition of specimen wiring; type of preconditionin

23、g (if applicable); initial measurements (if applicable); severity (see5.3); final measurements and requirements; measurement method according to EN2591-206 and insulation resistance value. 4 Apparatus The test chamber shall be designed so that its temperature is controlled by sensing devices located

24、 at those locations where the specimens are installed. 5 Method 5.1 Preconditioning Preconditioning shall take at least 1h unless otherwise specified. If required, the specimens shall be mated and unmated the number of times specified before testing. 5.2 Initial measurements (if applicable) They sha

25、ll be carried out as specified. 5.3 Severity The severity defined by the temperature and exposure time shall be selected from the list below. 5.3.1 Temperature ( 65 2) C ( 55 2) C ( 40 2) C 5.3.2 Exposure time 16h 5.4 Procedure When the test chamber is at the temperature corresponding to the specifi

26、ed severity, the specimens shall be introduced and connected to the measuring instruments. Exposure time shall be calculated from the moment the chamber has reached thermal stability. 5.5 Final measurements and requirements The specimens shall be subjected to a visual examination (EN2591-101). They

27、shall show no sign of deterioration which might affect performance. If applicable, EN2591-206 test shall be carried out 1h after completion of exposure. 1) Published as AECMA Prestandard at the date of publication of this standardBS EN 2591-310:1998 BSI 389 Chiswick High Road London W4 4AL BSIBritis
