Add a range of sieve sizes used in the test c. Address the calculation for using multiple sieves in series d. Add Note 2 about very fine mesh powder absorbing moisture from the air during the test (see Fred Caudill) a. What is ASTM STP 447B b. Clarify the sieve ultrasonic cleaning procedure referenced
