ASME B107.23-2004 pdf download.Pliers: Multiple Position, Adjustable.
1 SCOPE This Standard provides performance and safety re- quirements for adjustable joint and slip joint pliers. In- clusion of dimensional data in this Standard does not mean that all pliers described herein are stock produc- tion sizes. Consumers should consult with manufactur- ers concerning lists of stock production sizes. This Standard may be used as a guide by state author- ities or other regulatory bodies in the formulation of laws or regulations. It is also intended for voluntary use by es- tablishments that use or manufacture the covered tools. 2 CLASSIFICATION Type I: Adjustable joint, angle nose Class 1: Multiple grooves and tongue Style A: Straight, serrated jaws Style B: Curved, serrated jaws Style C: Parrot-nose jaws Style D: Straight, smooth jaws Class 2: Multiple hole Type II: Slip Joint, combination jaw Class 1: Straight nose Style A: Regular Style B: Thin Class 2: Bent nose 3 REFERENCES The following is a list of publications referenced in this Standard.

All figures are shown without comfort grips. Dimensions in tables are without comfort grips. Table values are in inches unless otherwise specified. 5.1 Design Pliers shall be similar to the figure to which reference is made and shall be proportioned in all parts so as to be strong, durable, and easy to operate. Pliers shall with- stand applicable test procedures without cracking or breaking. 5.1.1 Type I: Adjustable Joint, Angle Nose. Type I Pliers shall have jaws offset 37 deg to 56 deg as meas- ured between the centerline of the jaws and the cen- terline of the handles. The gripping surfaces shall have sharp, crosswise grooves the full length of the jaws, except for Style D pliers, which shall have smooth gripping surfaces. With the jaws parallel in any of the operating positions, the maximum distance between the outsides of the handles at their point of widest separation shall not exceed the values in Table 1 or 2. With the jaws parallel in the outermost oper- ating position, the work capacity of the jaws shall not be less than the minimum work capacity specified in Table 1 or 2. Handles shall not contact each other when the jaws are parallel in any of the operating po- sitions. 5.1.1.1 Class 1: Multiple Grooves, Tongue. Pliers shall have a number of curved grooves on one pliers half and a curved tongue on the other pliers half. The two pliers halves shall be held together by a joining member (i.e., fastener, rivet, or other). Changes in jaw capacity shall be made by sliding the joining member in a centrally located slot in the grooved pli- ers half. (a) Style A: Straight, Serrated Jaws. Pliers shall conform to the requirements shown in Table 1 and be similar to Fig. 1. (b) Style B: Curved, Serrated Jaws. Pliers shall conform to the requirements shown in Table 1 and be similar to Fig. 2.
(c) Style C: Parrot-Nose Jaws. Pliers shall conform to the requirements shown in Table 2 and be similar to Fig. 3. (d) Style D: Straight, Smooth Jaws. Pliers shall conform to the requirements shown in Table 1 and be similar to Fig. 4. 5.1.1.2 Class 2: Multiple Holes. Pliers shall have a number of holes on one pliers half, and a stationary joining member (i.e., fastener, rivet, or other) on the other pliers half. The joining member shall permit ad- justment of the two halves of the pliers and shall not disengage under load. Changes in jaw capacity shall be made by sliding the multiple hole side of the pliers on the joining member. Pliers shall conform to the re- quirements shown in Table 3 and shall be similar to Fig. 5. 5.1.2 Type II: SIip Joint, Combination Jaw. Pliers shall have two holes on one pliers half, and a station- ary joining member (i.e., fastener, rivet, or other) on the other pliers half. They may have a wire cutter. Changes in jaw position shall be made by slipping the double-hole side of the pliers on the joining member. Combination jaws shall have straight serrated gripping surfaces at the outer end of the jaws and curved ser- rated gripping surfaces behind the outer gripping sur- faces. 5.1.2.1 Class 1: Straight Nose. Pliers shall have a straight nose. (a) Style A: Regular. Pliers shall conform to the require- ments shown in Table 4 and shall be similar to Fig. 6. (b) Style B: Thin. Pliers shall conform to the require- ments shown in Table 5 and shall be similar to Fig. 7. 5.1.2.2 Class 2: Bent Nose. Pliers shall have a nose bent to an angle of 20 deg to 30 deg. The pliers shall conform to the requirements shown in Table 6 and be similar to Fig. 8. 5.2 Materials The materials used in the manufacture of the pliers shall be such as to produce pliers conforming to this Standard.
