(12.7 to 12.725 mm) inside diameter by 0.435 to0.439 in. (11.05 to 11.15 mm) wide, both components finishedto 32
10、 to 64 in (0.8 to 1.6 m) with 0.001 to 0.003 in. (0.025to 0.075 mm) diametrical clearance between the pin and collar(see Fig. 1). The pin and collar, by agreement, may be made ofany material (see Appendix X1), but the most commonmaterial is steel, as specified in Specification A108.7.1.2 Degrease al
11、l pins and collars (refer to Guide D2651),store in an atmosphere of low humidity (20 % relativehumidity), and keep them clean. Use degreased specimenswithin four days or discard. (Oxidation affects the test resultsafter this time. Prior to vapor degreasing, it is permissible tosoak or wash hard-grea

Load the specimen smoothly atabout 500 lb/s (2200 N/s) using a free crosshead speed of
20、 0.05in./min (1.3 mm/min). Record the maximum load in pounds(Newtons). Calculate the static shear strength by dividing thebreakaway load by the bond area as follows:Shear Strength 5 Maximum Load/Diameter 33.14 3Width9.
