It is the first editionof CSA Standard C22.2 No. 745-2-32 Safety of portable electric tools Part 2: Particular requirements formagnetic drill presses and UL 745-2-32 Safety of portable electric tools Part 2: Particular requirements formagnetic drill presses. It
36、 is written in SI (metric) units.This Standard was prepared by Canadian Standards Association and Underwriters Laboratories Inc. andis based on IEC Publication 745-1 (1982) Safety of hand-held motor-operated electric tools Part 1:General requirements.Where a particular clause of the general requirem
37、ents Standard is not mentioned in this Standard, theclause applies as far as is reasonable. Where this edition states addition, modification,orreplacement,the relevant requirement, test specification, or explanatory matter in the general requirements Standardshould be adapted accordingly.If the func
38、tions of a tool are covered by different particular Standards, the relevant particular requirementsStandard is applied to each function separately, so far as is reasonable. If applicable, the influence of onefunction on the other is taken into account.This Standard was reviewed by the CSA Subcommitt
39、ee on Portable Electric Tools of the TechnicalCommittee on Consumer and Commercial Products under the jurisdiction of the Standards SteeringCommittee on the Canadian Electrical Code, Part II, and was formally approved by these Committees.This Standard was processed and reviewed in accordance with th
40、e method of development, revision andimplementation of UL Standards for safety.This Standard has been approved by the Standards Council of Canada as a National Standard of Canadaand has been approved by the American National Standards Institute (ANSI) as an American NationalStandard.CSA Effective Da
