A phase for climatic conditioning shall be composed of the three parameters: temperature, relat
24、ive humidity and duration, that is one of each of those given in 6.2 to 6.4. For example: (30 f 3) OC, wet atmosphere, (24 f 1) h. A cycle may consist of one or more phases. Each specimen shall be placed in the conditioning environment such that air is free to circulate around it, and such that no c
25、omponent of the specimen has its weight supported by another, unless specifically intended by the manufacturer. Separate specimens shall not be touching. 6.2 Temperature The temperatures used for climatic conditioning shall be chosen from the following. 6.2.1 Manufacturers highest recommended temper
