There was a fair bit of interest in the subject of removing D My post to the thread referenced by cvg is still my opinion. The one for sampling and sieve testing will boggle your mind. Until you dive into the new standard for hydrometer tests. We are all to be legalists and worry about every little thing. Glad I am semi-retired. RE: astm d - withdrawn! Ron Structural 15 Mar 17 Apparently D18, the committee responsible for this standard, is working on a new combined standard which includes the hydrometer Scope This test method covers the quantitative determination of the distribution gradation of particle sizes in soils.

For particles larger than 0. The particle-size gradation distribution for particles smaller than 0. This method applies to soils in which both the coarse and fine fraction particle-size gradation distribution is desired.

This standard is needed to provide a standard in which specifiers can refer to when they want both a hydrometer and sieve analysis on a soil sample.

The other two standards are specific to either the hydrometer analysis or the sieve analysis independent of each other. This new combined method allows for on how to perform the testing when both analyses are required on a soil sample. Sure, we can compute our test results to as many decimal places as we want, but to what benefit.

It a Specific Gravity of 2. Or a Max density of Do we really need a prescribed pattern? Does it really matter when the next shovelful of earth from the same excavation is minutely different. We are dealing with SOIL.
