Repeat this process for each sieve in the nest. 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.

Series has been deleted and the columns for the Old U. A portion of 40 to 60 g shall be used when the apparent density of the powder is less than 1. NOTE 3—For some materials, for example brittle and friable materials, the 15 minutes may be too long. Weigh this fraction to the nearest 0. Sieving time may be adjusted for such materials, and the actual time used should be reported along with the test data.

NOTE 2—Use of a sound proof enclosure is recommended.
