2、), under whose auspices this National Standard has been produced, was chartered in 1919 and accredited by the Standards Council of Canada to the National Standards system in 1973. It is a not-for-profit, nonstatutory, voluntary membership association engaged in standards development and certificatio
3、n activities. CSA standards reflect a national consensus of producers and users including manufacturers, consumers, retailers, unions and professional organizations, and governmental agencies. The standards are used widely by industry and commerce and often adopted by municipal, provincial, and fede
4、ral governments in their regulations, particularly in the fields of health, safety, building and construction, and the environment. Individuals, companies, and associations across Canada indicate their support for CSAs standards development by volunteering their time and skills to CSA Committee work
5、 and supporting the Associations objectives through sustaining memberships. The more than 7000 committee volunteers and the 2000 sustaining memberships together form CSAs total membership from which its Directors are chosen. Sustaining memberships represent a major source of income for CSAs standard
6、s development activities. The Association offers certification and testing services in support of and as an extension to its standards development activities. To ensure the integrity of its certification process, the Association regularly and continually audits and inspects products that bear the CS
7、A Mark. In addition to its head office and laboratory complex in Toronto, CSA has regional branch offices in major centres across Canada and inspection and testing agencies in eight countries. Since 1919, the Association has developed the necessary expertise to meet its corporate mission: CSA is an
8、independent service organization whose mission is to provide an open and effective forum for activities facilitating the exchange of goods and services through the use of standards, certification and related services to meet national and international needs.For further information on CSA services, w
9、rite toCanadian Standards Association5060 Spectrum Way, Suite 100Mississauga, Ontario, L4W 5N6CanadaThe Standards Council of Canada is the coordinating body of the National Standards system, a federation of independent, autonomous organizations working towards the further development and improvement
10、 of voluntary standardization in the national interest. The principal objects of the Council are to foster and promote voluntary standardization as a means of advancing the national economy, benefiting the health, safety, and welfare of the public, assisting and protecting the consumer, facilitating
11、 domestic and international trade, and furthering international cooperation in the field of standards. A National Standard of Canada is a standard which has been approved by the Standards Council of Canada and one which reflects a reasonable agreement among the views of a number of capable individua
12、ls whose collective interests provide to the greatest practicable extent a balance of representation of producers, users, consumers, and others with relevant interests, as may be appropriate to the subject in hand. It normally is a standard which is capable of making a significant and timely contrib
13、ution to the national interest. Approval of a standard as a National Standard of Canada indicates that a standard conforms to the criteria and procedures established by the Standards Council of Canada. Approval does not refer to the technical content of the standard; this remains the continuing resp
14、onsibility of the accredited standards development organization. Those who have a need to apply standards are encouraged to use National Standards of Canada whenever practicable. These standards are subject to periodic review; therefore, users are cautioned to obtain the latest edition from the orga

It is the second edition of CAN/CSA-C22.2 No. 60745-2-1 and the second edition
31、of UL 60745-2-1. This standard is based on IEC 60745-2-1, second edition. The first edition of this standard was designated CAN/CSA-C22.2 No. 745-2-1/UL 745-2-1. This Standard CAN/CSA-C22.2 No. 60745-2-1/UL 60745-2-1, second edition, supersedes: a) the first edition of CAN/CSA-C22.2 No. 745-2-1/UL 7
32、45-2-1 published in 1995; and b) CAN/CSA-C22.2 No. 745-4-1/UL 745-4-1, (requirements for battery tools and battery packs are now incorporated into the requirements of CAN/CSA-C22.2 No. 60745-2-1, second edition, and UL 60745-2-1, second edition). This common standard was prepared by the Canadian Sta
33、ndards Association (CSA) and Underwriters Laboratories Inc. (UL). This standard was reviewed by the CSA Subcommittee on Portable Electric Tools, under the jurisdiction of the CSA Technical Committee on Consumer and Commercial Products and the CSA Strategic Steering Committee on Requirements for Elec
34、trical Safety, and has been formally approved by the CSA Technical Committee. This standard has been approved as a National Standard of Canada by the Standards Council of Canada and has been approved by the American National Standards Institute (ANSI) as an American National Standard. Note: Although
35、 the intended primary application 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. A UL standard is current only if it incorporates the most recently adopted revisio
36、ns, all of which are itemized on the transmittal notice that accompanies the latest set of revised requirements. Where reference is made to a specific number of samples to be tested, the specified number shall be considered a minimum quantity. Level of harmonization This standard adopts the IEC text
37、 with national differences. 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 t
38、hose recognized as being in accordance with NAFTA Article 905, for example because of fundamental climatic, geographical, technological, or infrastructural factors, scientific justification, or the level of protection that the country considers appropriate. Presentation is word for word except for e
39、ditorial changes. 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 development organization. If more than
40、 one literal interpretation has been identified, a revision is to be proposed as soon as possible to each of the standards development organizations to more accurately reflect the intent. CSA effective date The effective date for CSA International will be announced through CSA Informs or a CSA certi
41、fication notice. vi CAN/CSA-C22.2 NO. 60745-2-1-04 UL 60745-2-1 MARCH 26, 2004 UL effective date As of June 1, 2007, all products Listed or Recognized by UL must comply with the requirements in this Standard. Between March 26, 2004, and June 1, 2007, new product submittals to UL must be evaluated un
42、der all requirements in this Standard or, if requested in writing, evaluated under presently effective requirements only. The presently effective requirements are contained in the first edition of UL 745-2-1. Alternate constructions, currently listed to UL 45, eighth edition, may be evaluated to the
43、 first edition of UL 745-2-1 as referenced in the June 7, 2002, bulletin. General There are five types of National Differences as noted below. The difference type is noted on the first line of the National Difference in the standard. The standard may not include all types of these National Differenc
44、es. National Differences from the text of the International Electrotechnical Commission (IEC) publication 60745-2-1 (Hand-Held Motor-Operated Electric Tools Safety Part 2-1: Particular Requirements for Drills and Impact Drills) are indicated by the following notation: DR These are National Differenc
45、es based on the national Regulatory Requirements. D1 These are National Differences which are based on basic safety principles and requirements, elimination of which would compromise safety for consumers and users of products. D2 These are National Differences based on safety practices. These are di
46、fferences for IEC requirements that may be acceptable, but adopting the IEC requirements would require considerable retesting or redesign on the manufacturers part. DC These are National Differences based on the component standards and will not be deleted until a particular component standard is har
47、monized with the IEC component standard. DE These are National Differences based on editorial comments or corrections.
