Handles of pliers shall be hrough hardened from 30 to 50 HRC or case hardened from 75 10 86 HR15N, with a case depth of a minimum of 0.010讥. (0.25 mm). Handles shall be so shaped as to afford a comfort- able grip and shaUl be free from rough edges and sharp corDers. When the pliers are locked in any position of the, jaws, the minimum handle clearance betwcen the fixed and movable handle shall be as specified in the appropriate tables. Outer hand-gripping surfaces of handies shall be smooth, knurled, or impressed.
4.5 Joints Pliers joints shall have excessive looseness, play, or aoy other indications of side play of the two halves of be pliers when opened or closod, which could impair the function of pliers. Joint fasteners sball be through hardened from 25 to 50 HRC. Where fasteners reccive a case hardening reatmeat in addition to tbe through hardening. a maximum bardness of 60 HRC or equivalent will be pemitted.
4.6 Jaws 4.6.1 Jaw Openings. Ends of jaws hall open, when adjusted by the screw. to the entire respective clamping range minimum specifed in Tables 2 through 5. Pliers shail operate in a smoouh and uniform manner. 4.5.2 Jaw Hardness. Jaws shall be through bard- ened from 35 to 50 HRC or case hardened from 83 to 90 HRI5N, with a case depth minimun of 0.010 in. (0.25 mm). If provided, swivel pads need not be hardencd.
4.7 Adjusting Screw Adjusing scTeW located at the end of handle shall have a minimum hardness of 30 HRC.
4.8 Marking Plers shall be marked in a plain and permanent manber with the manufacturer’s oame or with a trade- mark of such known chanacter that the source of manufacture and county of origin can be readily deter- mined. Marking shall be as permanent as he normal life expectancy of the pliers, providing the surface has aOt been subjected to a fetting or abrading action, and be capable of withstanding the cleaning normally experienced during its intended use.
4.9 Finish 4.9.1 Appearance. Surfaces shall be tested in ac. cordance with ASME B46.1. Sufaces sball be free from pits, nodules, burrs, and other conditions that may adversely affect performance or appearunce. Ground surfaces shal have a maximum surfact roughness of 200 μin. (5.1 μm) arithmetic average. Measurement of the fnish shall be made with a measuring instrument using a cutoff length of 0.03 in. (0.8 mm). 4.9.2 Coating. Coating shall be adberenl, smooth, cootinuous, and free of pits, blisters, nodules, oxide scale, and any other cooditions that may interfere with tbe protective valce and serviceability of the pliens. Cadmium plate shall not be allowed. Pliers shall be coated with a supplementary Tust-preveouadive treatoenL
4.10 Spring Spring shall be capable of opening the jaws t0 the maximum value of the respective clamping range minimum dimension as specified in the tables for the individual type and class of pliers. 4.11 Dime nsions Dimensions shall be determined by measuring the pliers with jaws in the closed and locked position. The overall length measurement shall include the adjusting screw. 4.12 Workmanship Requirements within this Standard are intended to describe the best commercial quality pliers available. Pliers shall conform to the requiremneots of this Suandard.ASME B107.36 pdf download.
