FOREWORD

The American National Standards Committee B107, Socket Wrenches and Drives, under spon- sorship by The American Society of Mechanical Engineers, was reorganized as an ASME Standards Committee and its title was changed to Hand Tools and Accessories. In 1996 its scope was expanded to include safety considerations.

The purposes of this Standard are to define dimensional, performance, and safety requirements specifically applicable to socket wrenches for spark plugs and to specify test methods to evaluate performance relating to the defined requirements.

This Standard is a revision of B107.34M-1997, Socket Wrenches for Spark Plugs. Updated references, finish requirements, test requirements, and dimensional data are included.

The format of this Standard is in accordance with The ASME Codes & Standards Writing Guide 2000. Requests for interpretations and suggestions for the improvement of this Standard should be addressed to The American Society of Mechanical Engineers, Secretary, B107 Standards Com- mittee, Three Park Avenue, New York, NY 10016-5990.

The requirements of this Standard become effective at the time of publication. ASME B107.34- 2003 was approved as an American National Standard on May 1, 2003.

CORRESPONDENCE WITH THE B107 COMMITTEE

General. ASME Standards are developed and maintained with the intent to represent the consensus of concerned interests. As such, users of this Standard may interact with the Committee by requesting interpretations, proposing revisions, and attending Committee meetings. Correspondence should be addressed to:

Secretary, B107 Standards Committee

The American Society of Mechanical Engineers Three Park Avenue

New York, NY 10016-5990

Proposing Revisions. Revisions are made periodically to the Standard to incorporate changes that appear necessary or desirable, as demonstrated by the experience gained from the application of the Standard. Approved revisions will be published periodically.

The Committee welcomes proposals for revisions to this Standard. Such proposals should be as specific as possible, citing the paragraph number(s), the proposed wording, and a detailed description of the reasons for the proposal, including any pertinent documentation. Interpretations. Upon request, the B107 Committee will render an interpretation of any requirement of the Standard. Interpretations can only be rendered in response to a written

request sent to the Secretary of the B107 Standards Committee.

The request for interpretation should be clear and unambiguous. It is further recom- mended that the inquirer submit his/her request in the following format:

Subject: Cite the applicable paragraph number(s) and the topic of the inquiry.

Edition: Cite the applicable edition of the Standard for which the interpretation is being requested.

Question: Phrase the question as a request for an interpretation of a specific requirement suitable for general understanding and use, not as a request for an approval of a proprietary design or situation. The inquirer may also include any plans or drawings, which are necessary to explain the question; however, they should not contain proprietary names or information.

Requests that are not in this format may be rewritten in the appropriate format by the Committee prior to being answered, which may inadvertently change the intent of the original request.

ASME procedures provide for reconsideration of any interpretation when or if additional information that might affect an interpretation is available. Further, persons aggrieved by an interpretation 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 wishing to attend any meeting should contact the Secretary of the B107 Standards Committee.

4. REQUIREMENTS

   1. Figures

      The figures herein are descriptive and not restrictive, and are not intended to preclude the manufacture of sockets that are otherwise in accordance with this Standard.

      
      

   2. Materials

      The materials used in the manufacture of the sockets shall be such as to produce tools conforming to require- ments specified in this Standard.

      
      

   3. Marking

      Sockets shall be marked in a plain and permanent manner with the manufacturer’s name or with a trade- mark of such known character that the source of manu- facture and country of origin may be readily determined. In addition, sockets shall be marked in a plain and per- manent manner with the nominal size of the wrench opening (distance across flats).
