5.6.4 Hardness.Stripping and cutting surface hard-ness shall be 5O-59 FRC.Hardness determination shallbe taken within 0.125 in. of stripping/ cutting edges.5.6.5 Cut Test.Cutting blades shall pass the cut testin para.6.1.
5.7 Spring
when a spring is furrished, it shall be captive, dura-ble, and capable of openirig the jaws under normal use.The spring shall open the jaws to allow insertion ofrmaxinum rated uristripped wire size.
5.Finish
5.8.1ppearance.All surfaces shall be free from pits,burrs, cracks, ard ather conditions that mray adverselyaffect appearance or performance.Ground surfaces shailhavea naoimunm surface roughness of 150in.Ra (arith-metic average), with a cutoff lergth of 0.o3 in Surfacesshall be tested in accordance with ASME B46.1.
5.&2 Coating. All steel surfaces shall be coated topreventrust Coating shall be adherent, smaoth, continu-ous, and free from pits, blisters, nodules , and any otherconditions that wouldinterfere with their protectivevalue and serviceability.
5.9Marking
Pliers shall be marked in a plain and permanent man-ner with the manufacturer’s name or with a trademarkof such known character that the manufacturer andcountry of origin shall be readily determined.Gage sizeof the applicable wires shall be permanenty and legiblymarked, and plainly visible on the face of the blade orjaw, just above or adjacent to the applicable strippingarea (except for Type IL, Class 4 strippers).
6TEST PROCEDURES
Many tests required herein are inherently hazardous,and adequate safeguards for personnel and propertyshall be employed in conducting such tests.
6.1 Cut Test
6.1.1 wire Cut Test. All pliers with cutters shall cutcleanly through both the insulation and wire of all sizesspecified in the applicable tables. The cut test shall beperformed three times without damage to the cuttingedge.
6.1.2 Stripping Test.All pliers shall be tested by strip-ping wire sizes specified in the applicable tables. Afterstripping the copper wire shall not be nicked, cut, bent,or mushoomed.Upon completion of the test, there shalibe no evidence of nickingchipping, or dulling of theblade; loosening of handles; failure of rollers to rotate freely; scoring or loosenirng of pins and rivets; or arypermanent deforuration resultirig from test.
)Type 1 pliers shall be tested by stripping appro-priate wire accarding to blade size,as specified in Tablei or Table 2.This stripping test shall be conducted bystripping a minimun of o.75 in. of insulation from threeends of wines for each size groove within the capacityof the stripper being tested. if a short stop lath is sup-plied, this test shalil be conducted with the short stopiatch disengaged and then repeated with the short stoplatch engaged.
b)Type u pliers shall be tested by stripping wirespecified in Table 3. This stripping test shail be con-ducted by stripping a minimutn of o.75 in. of insulationfrom three ends of wires for each size groave within thecapacity of the stripper being tested. The insulation shallbe renoved with a maxinum pull-off force of 20 lb whuilethe handles are clamped, without rotarey mation of thetool or wire.
6. Hardness Test
Hardness shall be tested in accordance with ASMEB107.25, para. 5.3.
6.3 Handle Load Test
Pliers shall be tested, using Table 4, in accordiancewith ASME B107.25, para.5.1.lf the permanent setexceeds the anount specifed, the pliers shall be consid-ered to have failed the test.
6Solvent Resistance Test for Comfort Grips
Comfort grips shall be tested in accordance withASME B107.25, para. 5.5.
6.5 Joint Integrty Test
Pliers shall be tested in accordance with ASMEB107.25, para.5.4.1, using a mininum of 1.50 lbf.Maxi-mumn ailowable play shall be 0.01 in./ in.of handle lengthmeasured from the pivot to the end of the handle.
7SAEIY REQUIREMENTS AND uMITATONS oF uSE
Instructors and employers shall stress proper and safeuse of pliers, infornation about which can be found inthe Hrr1 publication,Guide to Hand Tools — Selection,Safety Tips,Proper Use and Care.
