Evaluation of Properties of Polymeric Materials
|Publication Date:||1 November 1992|
This Standard provides procedures for evaluating polymeric materials intended for application in electrical equipment covered by the Canadian Electrical Code, Part I, with respect to the following properties:
(d) resistance to weathering; and
The test procedures listed in this Standard are provided for referencing in the Standards forming Part II of the Canadian Electrical Code. Although the verbal auxiliary "shall" is used to state the requirements of each test procedure given, it is essential to recognize that the procedures are nonmandatory in themselves unless mandated by individual Standards.
Note: Most of these procedures are recognized internationally for evaluating polymeric material and are equally applicable to areas other than electrical.
This Standard provides procedures for making reproducible observations and serves as an aid in classifying materials according to the criteria set forth in the individual Standard.
The procedures described in this Standard involve standard size specimens tested under laboratory conditions and are intended to be used solely to measure and describe the properties of material. They are intended to serve as a preliminary indication of their acceptability for a particular application. The performance level of a material by these methods may vary in the end use application.
Test procedures for classifying electrical wires and cables are not specified in this Standard
