Hydrometer
Hydrometer
(OP)
Hello everyone,
A couple of times my boss mentioned a simplified hydrometer method. He said the method I use is very old and costly. But I am sure the way is still in the standard. He can not remember the exact name (may have phrase overnight). I search internet and have nothing clue for such thing. Any idea?

RE: Hydrometer
The older hydrometer test, as part of D422 is fairly simple and straight forward. Just requires a lot of attention to proper laboratory procedure. I have it performed for most classification tests. The test is being modified and may be a standard by now. The use of charts & simple calcs is a thing of the past. We are going to run the new & old methods w/calcs to compare what has really changed.
RE: Hydrometer
Do you mean that D422 have two parts. One is old and one is old. Honestly I have never read D422 thoroughly.
