The hold down arm of the sieve shaker shall be? A range of new pipe and wedge sensors featuring compact dimensions is ideal for the use in smaller flumes. Each of twelve laboratories made three tests on four powder samples using each of two sets of sieves. NOTE 3—For some materials, for example brittle and friable materials, the 15 minutes may be too long.
In many applications within the process, food and life sciences industries, the smallest amounts of a substance must be measured and added with a high degree of accuracy — whether in piping or in chemical reactors. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.
Other types of sieve shakers are also available, but their precision and reproducibility have not been determined. For in-house sieves R can be calculated from the following equations: A number in parentheses indicates the year of last reapproval. The number of rotations per asmt shall be between and Over time, the correcting results should continually be evaluated.
