12、ME). Itwas subsequently reorganized as an ASME Standards Committee, and its title was changed toHand Tools and Accessories. In 1996, the Committees scope was expanded to include safetyconsiderations.The purpose of B107.100 is to define essential performance and safety requirements specificallyapplic
13、able to combination wrenches; box wrenches, double head; open end wrenches, doublehead; flare nut; adjustable wrenches; and ratcheting box wrenches. It specifies test methods toevaluate performance related to the defined requirements and safety, and indicates limitationsof safe use.This Standard was
14、 designated “Wrenches” when it was first issued in 2002. It superseded thefollowing ASME standards: B107.6, Combination Wrenches; B107.9, Box Wrenches, Double Head;B107.39, Open End Wrenches, Double Head; and B107.40, Wrenches, Flare Nut.This current edition has been redesignated as “Flat Wrenches”
15、and incorporates the additionalfollowing standards:(a) B107.8, Adjustable Wrenches, approved by the American National Standards Institute onNovember 8, 2007(b) B107.21, Wrench, Crowfoot, approved by the American National Standards Institute onApril 5, 2005(c) B107.66, Ratcheting Box Wrenches, approv
16、ed by the American National Standards Instituteon November 8, 2007In addition to the consolidation of these individual wrench standards into B107.100, principalchanges are the uniform inclusion of performance requirements and test methods that evaluateboth performance and safety as well as uniform f
17、ormat for sections on definitions, references,performance requirements, tests, and safety requirements and limitations of use.Members of the Hand Tools Institute, Wrench Standards Committee through their knowledgeand hard work have been major contributors to the development of the B107 Standards. Th
18、eiractive efforts in the promotion of these standards are acknowledged and appreciated.The format of this Standard is in accordance with The ASME Codes however, they shouldnot contain proprietary names or information.Requests that are not in this format will be rewritten in the appropriate format by
19、 the Committeeprior to being answered, which may inadvertently change the intent of the original request.ASME procedures provide for reconsideration of any interpretation when or if additionalinformation that might affect an interpretation is available. Further, persons aggrieved by aninterpretation
20、 may appeal to the cognizant ASME Committee or Subcommittee. ASME does not“approve,” “certify,” “rate,” or “endorse” any item, construction, proprietary device, or activity.Attending Committee Meetings. The B107 Standards Committee regularly holds meetings,which are open to the public. Persons wishi
