24、andard for Extruded Insulating Tubing. It is the third edition of CSAC22.2 No. 198.1 and the sixth edition of UL 224. This harmonized standard has been jointly revised onAugust 12, 2010. For this purpose, CSA and UL are issuing revision pages dated August 12, 2010.This harmonized standard was prepar

25、ed by the Canadian Standards Association (CSA) and UnderwritersLaboratories Inc. (UL). The efforts and support of the Technical Harmonization Committee 15C, ElectricalTubing and Sleeving Products, of the Council on the Harmonization of Electrotechnical Standards of theNations of the Americas (CANENA

26、), are gratefully acknowledged.This Standard is considered suitable for use for conformity assessment within the stated scope of theStandard.This standard was reviewed by the CSA Subcommittee on Insulation Systems, under the jurisdiction ofthe CSA Technical Committee on Wiring Products and the CSA S

27、trategic Steering Committee onRequirements 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 ofCanada.This standard has been approved by the American National Standards

28、Institute (ANSI) as an AmericanNational Standard.Where reference is made to a specific number of samples to be tested, the specified number is to beconsidered a minimum quantity.Note: Although the intended primary application of this standard is stated in its scope, it is important to note that it r

29、emainsthe responsibility of the users of the standard to judge its suitability for their particular purpose.Level of harmonizationThis standard uses the IEC format but is not based on, nor is it to be considered equivalent to, an IECstandard.This standard is published as an equivalent standard for C

30、SA 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 thoserecognized as being in accordance with NAFTA Article 905, for example, because of fu

31、ndamental climatic,geographical, technological, or infrastructural factors, scientific justification, or the level of protection thatthe country considers appropriate. Presentation is word for word except for editorial changes.Reasons for differences from IECThe Technical Harmonization Subcommittee

32、identified the following standard as being within the scope ofthis standard: IEC 60684, Flexible Insulating Sleeving. IEC 60684 and CSA C22.2 No. 198.1/UL 224 aresimilar but not identical. Both standards cover multiple, but not identical, products and similar methods.The THC agreed to address the is

33、sues involved in the harmonization of these standards during the nextrevision of CSA C22.2 No. 198.1/UL 224.AUGUST 12, 2010CAN/CSA-C22.2 NO. 198.1-06 UL 2244UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION ORDISTRIBUTION WITHOUT PERMISSION FROM ULInterpretationsThe interpretation by t

37、 FOR FURTHER REPRODUCTION ORDISTRIBUTION WITHOUT PERMISSION FROM ULExtruded Insulating Tubing1 Scope1.1 This Standard specifies the requirements for insulating tubing that is usually round in cross-sectionand that consists entirely of extruded compounds whose characteristic constituents are thermose

38、tting,elastomeric, or thermoplastic polymers (see Table 1 for materials and ratings). These requirements alsocover heat-shrinkable and crosslinked tubing.1.2 Tubing is intended for use only in air in dry and damp locations as part of the internal wiring ofelectrical devices and appliances in accorda

39、nce with the Canadian Electrical Code, Part 1 (CE Code, Part1) and ANSI/NFPA 70, National Electrical Code (NEC). It may be used for insulating one or moreinadequately insulated conductors, bus bars, motor leads, transformer leads, terminal lugs, or smallassemblies of electronic components. Tubing is

40、 not intended for use in contact with sharp edges, corners,or projections, or where subject to tension, compression, or repeated flexing. Tubing is not intended foruse where it is feasible to employ a standard insulated conductor (appliance-wiring material) intendedspecifically for the purpose.1.3 T

41、hese requirements do not apply to fabric tubing, chemically dilated tubing, polymeric tubing extrudedwith reinforcement, or tubing intended only for mechanical protection.1.4 The acceptability of tubing in any particular device or appliance depends upon its acceptability forcontinued use under the c

42、onditions 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 thosespecified in these requirements. For example, tubing may be required to have a heavier wall thickness ora flat rat

43、her than a round cross-section; it may be required to have inherent resistance to the effects ofimmersion in water, oil, solvents, or other liquids (or their vapors); it may be required to be used in anenvironment conducive to the development of fungi and similar organisms.2 Reference Publications a
