Each of twelve laboratories made three tests on four powder samples using each of two sets of sieves. Precision and Bias4 9. A second set of sieves was chosen by each laboratory from its in-house sieve stock. Sieving time may be adjusted for such materials, and the actual time used should be reported along with the test data.
