What they ask about
Free sample question from ASTM.C704
Under the supplementary procedure, to what value is the air pressure regulated during a specimen test?
- A. 448 kPa, as in the standard procedure
- B. The pressure indicated by the most recent calibration of the tester ✓
- C. Whatever pressure gives a 450 s media flow time
- D. The maximum pressure that the air supply can hold without any fluctuation
- E. A pressure calculated from the specimen bulk density
The supplementary procedure replaces the fixed pressure setting, regulating instead to the pressure indicated by the most recent calibration of the abrasion tester, with the pressure checked before and after the media run. This is how the supplement achieves tighter precision than the fixed pressure approach. ASTM C704, S1.5.1
