28、 tools Part 2: Particular requirements for staplers and UL 745-2-30, Safety of portable electric tools Part 2: Particular requirements for staplers. It is written in SI (metric) units, It will coexist with the GSA Standard CAN/CSA-C22.2 No. 71.1 for the period given in CSA Certification Notice Elect
29、rical Tools No. 6. This Standard was prepared by the Canadian Standards Association and Underwriters Laboratories Inc. It contains particular requirements and is intended to be used in conjunction with the general Standard CAN!CSA-C22.2 No. 745-1/UL 745-1. Where a clause of the general Standard (CAN
30、/CSA-C22.2 No. 745-1/UL 745-1) is not mentioned in this Standard, the clause applies as far as is reasonable. Where this particular Standard states addition, modification, or replacement, the relevant requirement, test specification, or explanatory matter in the general Standard (CAN/CSA-C22.2 No. 7
31、45-1/UL 745-1) should be adapted accordingly. If the functions of a tool are covered by different particular Standards, the relevant particular Standard is applied to each function separately, so far as is reasonable. If applicable, the influence of one function on the other is taken into account. T
32、his Standard was reviewed by the CSA Subcommittee on Portable Electric Tools of the Technical Committee on Consumer and Commercial Products under the jurisdiction of the Standards Steering Committee on the Canadian Electrical Code, Part II, and was formally approved by these Committees. This Standar
33、d was processed and reviewed in accordance with the method of development, revision, and implementation of UL Standards for safety. This Standard has been approved by the Standards Council of Canada as a National Standard of Canada and it will be submitted to the American National Standards Institut
34、e (ANSI) for publication as an American National Standard. March 23, 1995 UL Effective Date As of June 1, 2007, all products Listed or Recognized by UL must comply with the requirements in this Standard. Between June 1, 2002 and June 1, 2007, new product submittals to UL must be evaluated under all

The presently eftective requirements are contained in the
36、seventh edition of UL 45. CSA Effective Date The effective date for CSA will be announced through CSA Certification Notice Electrical Tools No. 6. Note: Although the intended primary application of this Standard is stated in its Scope, it is important to note that it remains the responsibility of th
37、e users of the Standard to judge its suitability for their particular purpose. 6 CSA-C22.2 No. 745-2-30 UL 745-2-30 March 23, 1995 March 23, 1995 CSA-C22.2 No. 745-2-30 IJL 745-2-30 7 Foreword (CSA) Certification organizations, as accredited by the Standards Council of Canada, have their own criteri
38、a procedures for certification services. The following paragraphs define CSA Certification policies. The Canadian Standards Association provides certification services for manufacturers who, under license from CSA, wish to use the appropriate registered CSA Marks on certain products of their manufac
39、ture to 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. Where applicable, certification may form the basis for acceptance by
40、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 functions in accordance with its objectives, CSA does not assume or u
41、ndertake 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 necessity limitations of practical operation and state of the art at the time the Standard is process
42、ed. 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 Certification Division Operating Procedures. Products which comply with thi
43、s 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 Federal laws or regulations. Testing techniques, test procedures and instrumentat
44、ion 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 and Testing Division may require special cautions, markings and instructions that are n
45、ot 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 occur during or as the result of tests, wherever performed, whether performed in whole or in part by the ma
46、nufacturer or the Association, and whether or not any equipment, facility or personnel for 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 GSA Certification and Testing Division to resolve an issue ar
47、ising 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 GSA Certification please remember, when making application for certif
48、ication, to request all current Amendments, Bulletins, Notices and Technical Information Letters that may be applicable and for which there may be a nominal charge.
