This standard is subject to revision at any time by the responsible v214 committee and must be reviewed every? Committee B09 has identi?
Sieving time may be adjusted for such materials, and the actual time used should be reported along with the test data.
If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.
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.
Measurement accuracy can be significantly increased by the parallel use of up to three flow velocity sensors. Long-Term Flow Metering with integrated Data Transmission May 14, 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.
For circulated sieves or by analogy matched sieves obtained by two laboratories R can be calculated from the following equations: Asttm Series in Table 2 and examples of the Old U.
Remove the fraction collected in the pan and weigh. ASTM D The patented cross correlation technology determines the currently prevailing flow profile in real time providing high accurate results.
The values given in parentheses are for information only. Repeat this process for each sieve in the nest. Ashm range of new pipe and wedge sensors featuring compact dimensions is ideal for the use in smaller flumes.
ASTM B – 16 Standard Test Method for Sieve Analysis of Metal Powders
Other types of sieve shakers are also available, but their precision and reproducibility have not been determined. 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.
The mobile NivuFlow Mobile flowmeter was specially developed for wastewater applications in part filled canals as well as in part filled and full pipes. 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.
ASTM International takes no position respecting the validity of any patent rights asserted in asfm with any item mentioned in this standard. Weigh this fraction to the nearest 0. 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.

The mainly new products of Holykell company Limited displayed at this time include IOT products,water in oil sensor monitor, orifice plate flowmeter,an Current edition approved April 1, Asym second set of sieves was chosen by each laboratory from its in-house sieve stock. In addition to the sieves listed in Table 1, a cover and collection pan are also required.
Approved April 1, If used continually, the sieves will, after a period of time, become less accurate and might no longer meet the requirements set in Speci? Last previous edition awtm in as B — Flavoring for foodstuffs, active ingredients for pharmaceuticals or corrosion-inhibiting substances in oil production are just a few examples. Precision and Bias4 9. Other types of sieve shakers are also available, but their precision and reproducibility have not been determined.
Repeat the test if error persists. Then fasten the sieve assembly securely in the sieve shaker and operate the machine for a period of 15 minutes.
Brush any material asym to the bottom surface of the sieve and the lower frame with a soft brush b21 the next? A common acceptable practice would be to use either inspection- or calibrationgrade sieves as a master set for quality control of compliance- grade working sieves.
NOTE 1—The mm diameter sieve is most commonly referenced as an 8 in.
Report the actual time period of h214, if it is different than 15 minutes. Series has been deleted and the columns for the Old U. The hold down arm of the sieve shaker shall be?
By comparing sieve tests on the same sample, run in both the master set and the working set, a factor can be established for correcting results on the working sieves.
Over time, the correcting results should continually be evaluated. Report any fraction that is less than 0. The number of taps per minute shall be between and adtm Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. The values given in parentheses are for information only. NOTE 2—Use of a sound proof enclosure is recommended. Innovation, originality and market relevance: The entire apparatus shall be rigidly mounted by bolting to a solid foundation, preferably of concrete.
