Powder Sieve Analysis – ASTM B
Brush any material adhering to the bottom surface of the sieve and the lower frame with a soft brush into the next? Series has been deleted and the columns for the Old U. Other types of sieve shakers are also available, but their precision and reproducibility have not been determined. ASTM D It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Current edition approved April 1, This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?
No further reproductions authorized.
If used continually, the sieves will, after a period of asstm, become less accurate and might no longer meet the requirements set in Speci? Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. Add the difference between this sum and the mass of the test portion in accordance with Section 6 to the mass of the fraction collected in the pan.
A second set of sieves was chosen by each laboratory from its in-house sieve stock. The number of taps per minute shall be between and The number of rotations per minute shall be between and Measurement accuracy can be significantly increased by the parallel use of up to three flow velocity sensors.
Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. Last previous edition approved in as B — Each of twelve laboratories made three tests on four powder samples using each of two sets of sieves. In addition to the sieves listed in Table 1, a cover and collection pan are also required.
Report the actual axtm period of sieving, if it is different than 15 minutes. 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.
ASTM B – 07 standard test method for sieve analysis of metal powders 0. No comments were found for ASTM B – 07 standard test method for sieve analysis of metal powders. Repeat the test if error persists. The test method may be part of the purchase agreement between powder supplier and user, or it may be an internal quality control test for either.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Report any fraction that is less than 0. Other types of sieve shakers are also available, but their precision and reproducibility have not been determined. The values given in parentheses are for information only.
Powder Sieve Analysis – ASTM B214
For circulated sieves or by analogy matched sieves obtained by two b21 R can be calculated from the following equations: Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
Weigh this fraction to the nearest 0. A portion of 40 to 60 g shall be used when the apparent density of the powder is less than 1. Innovation, originality and market relevance: Standard Series in Table h214 and examples of the Old U.
NOTE 2—Use of a sound proof enclosure is recommended.
The test method may be part of the purchase agreement between powder supplier and user, or it may be an internal quality control test for either. Axtm number in asgm indicates the year of last reapproval. For in-house sieves R can be calculated from the following equations: The mobile NivuFlow Mobile flowmeter was specially developed for wastewater applications in part filled canals as well as in part filled and full pipes.
One set of sieves was a standard set that was circulated to each laboratory in turn.
