The values given in parentheses are for information only. Sieving time may be adjusted for qstm materials, and the actual time used should be reported along with the test data. Over time, the correcting results should continually be evaluated. Other types of sieve shakers are also available, but their precision and reproducibility have not been determined. For circulated sieves or by analogy matched sieves obtained by two laboratories R can be calculated from the following equations: Series and TylerSieve Series have also been deleted.
