May, 1983 6 CSA Standard C22.2 No. 197-M1983 Foreword The Canadian Standards Association provides certi- fication services for manufacturers who, under license from CSA, wish to use the
17、 appropriate registered CSA Marks on certain products of their manufactureto indicate conformity with CSA Standards. CSA Certification for a number of products is provided in the interest of maintaining agreed-upon standards of quality, performance, interchangeability and/or safety, as appropriate.
18、Where applicable, certification may form the basis for acceptance by inspection authorities responsible for enforcement of regulations. Where feasible, programs will be developed for additional products for which certification is desired by producers, consumers or other interests. In performing its
19、functions in accordance with its objectives, CSA does not assume or undertake to discharge any responsibility of the manufacturer or any other party. The opinions and findings of the Association represent its professional judgement given with due consideration to the necessary limitations of practic
20、al operation and state of the art at the time the Standard is processed. Products in substantial accord with this Standard but which exhibit a minor difference or a new feature may be deemed to meet the Standard providing the feature or difference is found acceptable utilizing appropriate CSA Certif
21、ication Division Operating Procedures. Products which comply with this Standard shall not be certified if they are found to have additional features which are inconsistent with the intent of this Standard. Products shall not be certifiable if they are discovered to contravene applicable laws or regu
22、lations. Testing techniques, test procedures and instrumentation frequently must be prescribed by the CSA Certification Division in addition to the technical requirements contained in Standards of CSA. In addition to markings specified in the Standard the CSA Certification Division may require speci
23、al cautions, markings and instructions that are not specified by the Standard. Some tests required by CSA Standards may be inherently hazardous. The Association neither assumes nor accepts any responsibility for any injury or damage that may occurduring oras the result of tests, wherever performed,
24、whether performed in whole or in part by the manufacturer or the Association, and whether or not any equipment, facility or personnel for or in connection with the test is furnished by the manufacturer or the Association. Manufacturers should note that, in the event of the failure of the CSA Certifi
25、cation Division to resolve an issue arising from the interpretation of requirements, there is an appeal procedure: the complainant should submit the matter, in writing, to the Secretary of the Canadian Standards Association. If this Standard is to be used in obtaining CSA Certification please rememb
26、er, when making application for certification, to request all current Amendments (see General Instruction page), BulLetins, Notices and Technical Information Letters that may be applicable and for which there may be a nominal charge. For such information or for further information concerning details
27、 about CSA Certification please address your inquiry to the Applications and Records Section, Canadian Standards Association, 178 Rexdale Boulevard, Rexdale (Toronto), Ontario M9W 1R3.

29、n. May, 1983 C22.2 No. 197-M1983 PVC insulating Tape 7 1. Scope. This Standard applies to polyvinyl chloride (PVC) insulating tape for use at a maximum temperature of 60, 80, 90 or 105 C, for insulating joints and splices in wires and cables having voltage ratings up to 1000 V, in accordance with th
30、e Canadian Electrical Code, Part I. The tape is intended to be applied in layers, each layer being half-lapped, and each joint or splice insulated so as to provide an acceptable level of insulation. 2.
