10、specimens for each test as described inthe following paragraphs:7.1.1 Each specimen is comprised of a pin 0.498 to 0.499 in.(12.65 to 12.675 mm)in diameter and a slip collar 0.500 to0.501 in.(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
11、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 all pins and c
12、ollars(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-greased or waxed parts in
