I
13、t wassubsequently reorganized as an ASME Standards Committee, and its title was changed to HandTools and Accessories. In 1996, the Committees scope was expanded to include safety considera-tions.The purpose of B107.500 is to define essential performance and safety requirements for severaltypes of pl
14、iers, including long nose pliers, shears, electronic pliers, and wire cutters. It specifiestest methods to evaluate performance related to the defined requirements and safety and indicateslimitations of safe use.This Standard may also be used as a guide by state authorities or other regulatory bodie
15、s inthe formulation of laws or regulations. It is also intended for voluntary use by establishmentsthat use or manufacture the instruments covered.This Standard includes the following:B107.11 Pliers: Diagonal Cutting and End Cutting, approved by the American NationalStandards Institute on December 4

21、ety, as well as a uniform format for sections on definitions, references,performance requirements, tests, and safety requirements and limitations of use.Members of the Hand Tools Institute Pliers Standards Committee through their knowledgeand hard work have been major contributors to the development
22、 of the B107 Standards. Theiractive efforts in the promotion of these standards is 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 may be rewritten in t
23、he appropriate format by 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 aggri
24、eved by aninterpretation 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.

28、 suitable for cutting wire. Pliersshall have cutting edges diagonal to or at right anglesto their longitudinal axis. Inclusion of dimensional datain this Standard does not mean that all productsdescribed herein are stock production sizes, nor that allproduction sizes are listed. Consumers should con
29、sultwith manufacturers concerning lists of stock produc-tion sizes.This Standard may be used as a guide by state authori-ties or other regulatory bodies in the formulation of lawsor regulations. It is also intended for voluntary use byestablishments that manufacture the tools covered.2 DEFINITIONSDe

33、intended to preclude themanufacture of pliers that otherwise comply with thisStandard. All figures are shown without comfort grips.Pliers shall withstand applicable tests without crackingor breaking.5.1 DesignPliers shall be similar to the figure to which referenceis made and shall be proportioned i
34、n all parts so as tobe strong, durable, and easy to operate.
