This is the harmonized CSA Group and UL standard for Coated Electrical Sleeving. It is the third edition of CSA C22.2 No. 198.3 and the fifth edition of UL 1441. This edition of CSA C22.2 No. 198.3 supersedes the previous edition(s) published published in 1995 and 2005. This edition of UL 1441 supersedes the previous edition published on November 27, 2018. This harmonized standard has been jointly revised on November 3, 2022. For this purpose, CSA Group and UL are issuing revision pages dated November 3, 2022.
This harmonized standard was prepared by the CSA Group and Underwriters Laboratories Inc. (UL). The efforts and support of the Technical Harmonization Committee 15C (Electrical Tubing and Sleeving Products) of the Council on the Harmonization of Electrotechnical Standards of the Nations of the Americas (CANENA) are gratefully acknowledged.
This standard is considered suitable for use for conformity assessment within the stated scope of the standard.
This standard was reviewed by the CSA Subcommittee on Insulation Systems, under the jurisdiction of the CSA Technical Committee on Wiring Products and the CSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the CSA Technical Committee. This standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.
The requirements of this Standard apply to Grades A and B acrylic-polymer-coated, siliconepolymer-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 CSA C22.1, Canadian Electrical Code, Part I, (CE Code, Part 1), or ANSI/NFPA 70, National Electrical Code (NEC). A product for use at temperatures greater than indicated in 1.2 or a different polymer coating or fiber 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.
These requirements apply to coated electrical sleeving having a standard temperature index classification of 105, 130, 155, 180, 200, 220, and 240 °C.
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.
These requirements apply to oil-resistant coated electrical sleeving intended for occasional or intermittent contact with oil.
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.
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.
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.
