5.1.2 Type ll: Die Setter, Pry bars shall have a benthalf loop chisel end for separating or prying applicationsand a straight chisel end for scraping or prying
5.1.3 Type Ill: Handled. Pry bars shall have a slightlybent chisel end for separating, scraping, or prying appli-cations and a handle grip.
5.1.4 Type V: Pinch, Pry bars shall have a slightlybent chisel end for separating, scraping, or prying applications and a pointed end for alignment applications.5.1.5 Type V: Rolling Head. Pry bars sha!l have aformed rounded chisel end that acts as a fulcrum toprovide leverage and a pointed end for alignment appli-cations.
5.2 Materials
The materials used in the manufacture of pry barsshall be such as to produce pry bars conformning to therequirements specified herein.
5.3 Mechanical Properties
Pry bars shall have a maximum hardness of 50 HRCor equivalent.
5.4 Surface Conditions
Pry bars shall be free of nonfunctional sharp edges.points, and surface roughuress that could inflict personalinjury to the user or adversely affect performance
TESTS
Many tests required herein are inherently hazardousand adequate safeguards for personne! and propertyshall be employed in conducting such fests. Tests shallbe conductcd at a temperature between 40F and 90FSeparate (new) samples shall be used for each testFailure to meet the requirements of the applicable testsindicates that the pry bars do not comply with thisStandard.
6.1 Hardness
Hardness determination shall be made in accordancewith ASTM E18
6.2 Prying Tests
6.2.1 Prying End Test. The load shall be applied nearthe middle of the handle or grip area of the pry bar (secFig. 6) Apply a slow, steady load to the pry bar fo meetthe torque specified in Table 1. If the blade or tp failstakes a permnanent sct, or if the handle loosens fromn thepry bar, the pry bar has failed this test.
6.2.2 Point End Test, The load shall be applied nearthe middle of the handle or grip arca of the pry bar (seeFig. 7). Apply a slow, steady load to the pry bar to meetthe minimum bend angle specifed i Table 2. The pry
