Table 2 Test conditions Temperature (T) Relative Humidity (RH) Total Assembly Mass g 21,0 C to 25,0 C 50,0% RH 10,0 % 100,0 +/- 5,0 g 3.3 Apparatus The apparatus shall include the following elements: Traceable, calibrated gauge pins of tungsten carbide steel, 0,698 95 mm to 0,700

26、05 mm in 100 nm increments; Pin vice with rod and platform to hold calibrated mass elements, the mass of which is sufficient to make the entire assembly 100,0 g total. Fixturing should ensure that the assembly is free to hang vertically during testing. Both pins and test parts should be as clean as

27、possible to ensure an accurate measurement. 4 Procedure Parts should be preconditioned using the conditions in 3.2 for a minimum of 24 hours. Once conditioned, a calibrated gauge pin is pushed into the ferrule until it clears the ferrule end as shown in Figure 1. Start with a pin that should fit fre

28、ely in the part under test. Rear entry is recommended where possible to reduce the risk of ferrule end face damage. (For fully assembled product, front entry may be used as an alternative to disassembly as shown in Figure 3.) After the pin engages the full bore ID length, the pin vice is secured to

29、the calibrated gauge pin/ferrule vice assembly as shown in Figure 2. The mass is gradually released, pulling the pin through the bore. This procedure is repeated using increasingly larger pins until the 100,0 g 5,0 g mass cannot freely pull the pin out of the bore. Once this state is reached, the pr

30、evious pins diameter is recorded as the effective diameter of the guide pin bore. Repeat the above procedure for the opposite hole.
