Preface
This is the common CSA and UL standard for Coated electrical sleeving. It is the second edition of CSA C22.2 No. 198.3 and the fourth edition of UL 1441.
This edition of CSA C22.2 No. 198.3 supersedes the previous edition published in 1995.
This edition of UL 1441 supersedes the previous edition published in 1995.
This standard will be submitted to the Standards Council of Canada (SCC) for approval as a National Standard of Canada.
This standard has been approved by the American National Standards Institute (ANSI) as an American National Standard
Scope
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.
1.2
These requirements apply to coated electrical sleeving having a standard temperature index classification of 105, 130, 155, 180, 200, 220, and 240 °C.
1.3
These requirements apply to coated electrical sleeving intended for use in connection with the internal wiring of electrical devices and appliances located in dry or damp locations where it is not feasible to employ a standard insulated conductor, such as appliance-wiring material, specifically intended for the purpose. Coated electrical sleeving is intended for insulating one or more uninsulated or partially insulated conductors, bus bars, component leads, or assemblies of electrical components. Coated electrical sleeving may be employed in equipment where it is not subjected to repeated flexing or severe mechanical stress.
1.4
These requirements apply to oil-resistant coated electrical sleeving intended for occasional or intermittent contact with oil.
1.5
These requirements do not apply to unimpregnated or uncoated fabric sleeving, which is generally not considered acceptable for sole (functional) insulation because of the openings inherent in the weave construction of the sleeving fabric.
1.6
These requirements do not apply to tubing extruded with reinforcement, extruded electrical tubing, or tubing intended only for mechanical protection, since they are covered by other requirements.
1.7
These requirements do not apply to coated electrical sleeving when it is employed as splice insulation in an insulation system above 105 °C (Class A) operation.
