astm d422 - withdrawn!

astm d422 - withdrawn!

astm d422 - withdrawn!

(OP)
Just heard. Can't quite believe! Checked it out myself and it seems true.

Anybody out there know what's going on? Is there a new standard citation?

RE: astm d422 - withdrawn!

Interesting, as this is certainly a well-known standard (fyi https://www.astm.org/Standards/D422.htm). This appears to says the standard was withdrawn in that it was not "updated" within an 8 years window required - a little odd, unless it has been replaced e.g. with e.g. separate new standards of narrower scope not explained here, in that this has certainly been a well-known standard in soil engineering/testing and hard to believe no one now has interest in the subject.

RE: astm d422 - withdrawn!

There was a fair bit of interest in the subject of removing D422.
My post to the thread referenced by cvg is still my opinion.
"New standards. The one for sampling and sieve testing will boggle your mind. Until you dive into the new standard for hydrometer tests. I understand the limitations of the old D 422, but I question the trying to 'legislate' every possible condition or trying for excess accuracy when it is really not needed. But my father was complaining about this sort of thing back in the 80's when he was on the committees.".
We are all to be legalists and worry about every little thing. Glad I am semi-retired.

RE: astm d422 - withdrawn!

Apparently D18, the committee responsible for this standard, is working on a new combined standard which includes the hydrometer....here is the workgroup's synopsis.....


ASTM WK38106

New Test Method for Particle Size Anaylsis For Soils Combining The Sieve and Sedimentation Techniques

Developed by Subcommittee: D18.03 | Committee D18

WK38106

1. Scope

This test method covers the quantitative determination of the distribution (gradation) of particle sizes in soils. For particles larger than 0.075 mm (No. 200) sieve, the particle-size (gradation)distribution is determined by sieving. The particle-size (gradation) distribution for particles smaller than 0.075 mm (No. 200) sieve is determined by the sedimentation process. 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.

RE: astm d422 - withdrawn!

I wonder about the ever-tightening regulations. Sure, we can compute our test results to as many decimal places as we want, but to what benefit. It a Specific Gravity of 2.701 really different from one at 2.691? Or a Max density of 124.6 significantly different from one at 125.0? Isn't evenly distributing the rammer blows for a proctor clear enough? 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.

RE: astm d422 - withdrawn!

density a bit higher?

RE: astm d422 - withdrawn!

ASTM D 7928-16 is the replacement standard for the hydrom portion only.

RE: astm d422 - withdrawn!

Don't you all yearn for the days of Lambe's Soil Test book . . . . Don't worry - by 2020, they will probably require all testing personnel to wear yellow shirts . . . being facetious of course

RE: astm d422 - withdrawn!

Speaking of Lambe's book....
I remember seeing a spoof soils manual, done by, IIRC, some students at Harvard. During one discussion they replaced a greek symbol with a Chinese one, "for clarity". I believe there were also instructions for large-scale Triaxial test that required a sacrificial technician.

Anyone else remember that? Anyone have a copy?
It probably dated form the 1960's or even the early-to-mid 1970's

RE: astm d422 - withdrawn!

Not aware of it - but it doesn't surprise me. Soils students and practicioners years ago had a sense of humour. At Cornell, two of our classmates got married and we developed a "Standard Penetration Test for Honeymooners!" Lost my copy though.
