24、RMISSION FROM UL Preface This is the harmonized CSA and UL standard for Extruded Insulating Tubing. It is the third edition of CSA C22.2 No. 198.1 and the sixth edition of UL 224. This harmonized standard has been jointly revised on August 12, 2010. For this purpose, CSA and UL are issuing revision
25、pages dated August 12, 2010. This harmonized standard was prepared by the Canadian Standards Association (CSA) 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 o
26、f 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 juris
27、diction 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 approved by the Standards Council of Canada (SCC) as a National Standard of
28、Canada. This standard has been approved by the American National Standards Institute (ANSI) as an American National Standard. Where reference is made to a specic number of samples to be tested, the specied number is to be considered a minimum quantity. Note: Although the intended primary application
29、 of this standard is stated in its scope, it is important to note that it remains the responsibility of the users of the standard to judge its suitability for their particular purpose. Level of harmonization This standard uses the IEC format but is not based on, nor is it to be considered equivalent
30、 to, an IEC standard. This standard is published as an equivalent standard for CSA and UL. An equivalent standard is a standard that is substantially the same in technical content, except as follows: Technical national differences are allowed for codes and governmental regulations as well as those r
31、ecognized as being in accordance with NAFTA Article 905, for example, because of fundamental climatic, geographical, technological, or infrastructural factors, scientic justication, or the level of protection that the country considers appropriate. Presentation is word for word except for editorial
32、changes. Reasons for differences from IEC The Technical Harmonization Subcommittee identied the following standard as being within the scope of this standard: IEC 60684, Flexible Insulating Sleeving. IEC 60684 and CSA C22.2 No. 198.1/UL 224 are similar but not identical. Both standards cover multipl
33、e, but not identical, products and similar methods. The THC agreed to address the issues involved in the harmonization of these standards during the next revision of CSA C22.2 No. 198.1/UL 224.

34、ODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL Interpretations The interpretation by the standards development organization of an identical or equivalent standard is based on the literal text to determine compliance with the standard in accordance with the procedural rules of the standards deve
35、lopment organization. If more than one interpretation of the literal text has been identied, a revision is to be proposed as soon as possible to each of the standards development organizations to more accurately reect the intent. CSA effective date The effective date for CSA International will be an
36、nounced through CSA Informs or a CSA certication notice. UL effective date As of August 12, 2010 all products Listed or Recognized by UL must comply with the requirements in this standard. A UL effective date is one established by Underwriters Laboratories Inc. and is not part of the ANSI approved s
37、tandard. AUGUST 12, 2010 CAN/CSA-C22.2 NO. 198.1-06 UL 224 5UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL Extruded Insulating Tubing 1 Scope 1.1 This Standard species the requirements for insulating tubing that is usually round in cross-se
38、ction and that consists entirely of extruded compounds whose characteristic constituents are thermosetting, elastomeric, or thermoplastic polymers (see Table 1 for materials and ratings). These requirements also cover heat-shrinkable and crosslinked tubing. 1.2 Tubing is intended for use only in air
39、 in dry and damp locations as part of the internal wiring of electrical devices and appliances in accordance with the Canadian Electrical Code, Part 1 (CE Code, Part 1) and ANSI/NFPA 70, National Electrical Code (NEC). It may be used for insulating one or more inadequately insulated conductors, bus
40、bars, motor leads, transformer leads, terminal lugs, or small assemblies of electronic components. Tubing is not intended for use in contact with sharp edges, corners, or projections, or where subject to tension, compression, or repeated exing. Tubing is not intended for use where it is feasible to
41、employ a standard insulated conductor (appliance-wiring material) intended specically for the purpose. 1.3 These requirements do not apply to fabric tubing, chemically dilated tubing, polymeric tubing extruded with reinforcement, or tubing intended only for mechanical protection. 1.4 The acceptabili
42、ty of tubing in any particular device or appliance depends upon its acceptability for continued use under the conditions that prevail in actual service. Accordingly, for a particular application, it will in some cases be necessary to employ tubing having features other than or in addition to those s
43、pecied in these requirements. For example, tubing may be required to have a heavier wall thickness or a at rather than a round cross-section; it may be required to have inherent resistance to the effects of immersion in water, oil, solvents, or other liquids (or their vapors); it may be required to
44、be used in an environment conducive to the development of fungi and similar organisms. 2 Reference Publications and Denitions 2.1 Reference publications For undated references to standards, such reference shall be considered to refer to the latest edition and all revisions to that edition up to the
