Doplňujúce informácie
| Significance and Use | ||||
|
This practice can be used to prepare samples for particle-size and plasticity tests where it is desired to determine test values on air-dried samples, or where it is known that air drying does not have an effect on test results relative to samples prepared in accordance with Practice D 2217. |

| 1. Scope | ||||
|
1.1 This practice covers the dry preparation of soil samples as received from the field for particle-size analysis and the determination of the soil constants. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. |
