- Scope
- Scope 1.1 This standard presents methods for evaluating polymeric materials and parts made from these materials that may be used in electrical equipment covered by the Canadian Electrical Code, Part II, with respect to relates to the following properties: (a) flammability; b) mechanical properties; c) thermal properties; (d) resistance to aging due to bad weather; and e) electrical properties. 1.2 The test procedures in this standard are given for use as references in the standards that constitute the Canadian Electrical Code, Part II. Although the term "shall" is used to state the requirements for each given test procedure, it is essential to recognize that procedures are only mandatory when they are prescribed under separate standards. Note: Many of these methods are internationally recognized for the evaluation of polymer materials and are also applicable to areas other than electricity. 1.3 This standard contains methods that give reproducible results and allows the classification of polymer materials according to the criteria set out in each standard. 1.4 The procedures described in this standard relate to standard-sized specimens, tested under laboratory conditions, and are used only to measure and define the properties of the polymer. They are intended to serve as a preliminary indication of the acceptability of the material for a particular use. The performance of a material, determined by these methods, could vary depending on its final use. 1.5 No test procedure for the classification of electrical wires and cables is specified in this standard. 1.6 The test methods described in this standard include procedures for evaluating material integrity, electrical properties and reaction to fire. 1.7 Evaluation of electrical components produced using additive manufacturing (AM) processes will be carried out in accordance with the relevant clauses of this standard, where applicable. Notes: 1) This standard may cover hazardous materials, operations and equipment. This standard does not claim to address all safety issues related to its use. It is the user's responsibility to establish appropriate safety and hygiene measures and to determine, in advance, what regulatory restrictions apply. 2) This standard should be used to measure and determine the properties of materials, products and assemblies subjected to heat or exposed to flame under controlled laboratory conditions, and should not be used to describe or evaluate hazards or the fire dangers of materials, products or assemblies under real fire conditions. However, the results of each test can be used as part of a fire risk assessment, which takes into account all factors relevant to a particular use. 3) The test methods described in this standard are not intended to establish fire hazard criteria. The risks posed by materials depend on their form and end use. Fire danger assessment includes many factors, including but not limited to ease of ignition, surface burning rate, flame spread, fuel input, intensity combustion and combustion products. 1.8 In this standard, the term “shall” indicates a requirement, that is, a requirement that the user is obliged to comply with to ensure compliance with the standard; “should” indicates a recommendation or what is advisable but not obligatory to do; and “may” indicates a possibility or what is permitted to be done. The notes that accompany the articles do not include prescriptions or recommendations. They are used to separate from the text explanations or information that are not properly part of the document. Notes at the bottom of figures and tables are part of these and can be written as prescriptions. The annexes are qualified as normative (mandatory) or informative (optional) to clarify their application.
