1 .1 The requirements of this Standard apply to Grades A and B acrylic-polymer-coated,silicone-polymer-coated, or vinyl-polymer-coated electrical sleeving that consists of closely woven fabric made from glass (see Table 1 for materials and ratings) and intended for use in equipment designed to be installed and used in accordance with the rules of the Canadian Electrical Code, Part I (CEC), or ANSI/NFPA 70, National Electrical Code (NEC). A product for use at temperatures greater than indicated in Clause 1.2 or a different polymer coating or fibre may be acceptable provided that
(a) it meets the performance tests in this Standard; and
(b) long-term heat-aging tests are conducted as covered in UL 746B or CAN/CSA-C22.2 No.0.17, using dielectric strength as a primary property and flammability as a secondary property.
