Precision and Bias4 9. This standard has been approved for use by agencies of the U. A portion of 40 to 60 g shall be used when the apparent density of the powder is less than 1.

Report the actual time period of sieving, if v214 is different than 15 minutes. Report any fraction that is less than 0. Series has been deleted and the columns for the Old U. One set of sieves was a standard set that was circulated to each laboratory in turn. By comparing sieve tests on the same sample, run astk both the master set and the working set, a factor can be established for correcting results on the working sieves.

Sieving time may be adjusted for such materials, and the actual time used should be reported along with the test data. Customer comments No comments were found for ASTM B – 07 standard test method for sieve b24 of metal powders.

Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. 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.

Approved October 1, A common acceptable practice would be to use either asrm or calibrationgrade sieves as a master set for quality control of compliance- grade working sieves. Then fasten the sieve assembly securely in the sieve shaker and operate the machine for a period of 15 minutes. Proline Promass A for lowest flow rates Aug.

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. A b124 of new pipe and wedge sensors featuring compact dimensions is ideal for the use in smaller flumes.

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: The newly developed Promass A measures such substances drop-for-drop with a precision unmatched worldwide. 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. Tap the sieve just removed upside down, on the paper containing the portion that had been retained on it, and brush the back side of the sieve with the?

Repeat this process for each sieve in the nest. NOTE 2—Use of a sound proof enclosure is recommended. Over time, the correcting results should continually be evaluated. Weigh this fraction to the nearest 0. 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.
