It is my understanding customers wanted an option to specify only the fine PSA or only the coarse PSA at one time, and this perhaps played a part in why D422 … Test Property. Formerly under the jurisdiction of Committee D18 on Soil and Rock, this test method was withdrawn in January 2016 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date. Technically ASTM D422 has been withdrawn; I've read some studies showing that the estimated particle sizes from the hydrometer portion of the test can be underestimated by up to two orders of magnitude due to the assumption of Stokes Law of falling spheres vs the disk or other shapes of real clay particles. 113 0 obj <> endobj 200 sieve) is determined by sieving, while the distribution of particle sizes smaller than 75 μm is determined by a sedimentation process, using a hydrometer to secure the necessary data. 1.1 This test method covers the quantitative determination of the distribution of particle sizes in soils.
