However, the applicable sections above should be used in applying this standard. This test method is used to separate particles into size ranges and to determine quantitatively the mass of particles in each range. Jar and Small Bag Samples.
The alterations could require the washing and sieving procedures to be standardized such that each specimen would be processed in a similar manner. Link to Active This link will always route to the current Active version of the standard. Typical examples of these soils are some residual soils, most weathered shales and some weakly cemented soils such as hardpan, caliche or coquina. This test method uses a square opening sieve criterion in determining the gradation of soil between the 3-in.
Low Temperature Drying Oven optional.
ASTM D Standard
Add to Alert PDF. Dry Sieving Coarser Portion. Percent Passing, 2 f6913 Coarser Portion. Composite Sieving, Single Separation. However, the use of balances or scales recording pounds of mass lbm shall not be ashm as nonconformance with this standard. Finally, if the maximum particle qstm is equal to or greater than 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.
A representative specimen must be obtained from the sample by one of three procedures moist, air-dried or oven-dried. Discussion on Segregating Soils. For cases of disputes, Method A is the referee method.
Soil testing Back to Results Print. These data are combined to determine the particle-size distribution gradation.
Active Risk Management
These data are combined to determine the particle-size distribution gradation. Using an Ultrasonic Water Bath. Only the SI units are used for mass determinations, calculations and reported results. Please first log in with a verified email before subscribing to alerts. Prior to sieving, as applicable, the material will be washed to remove fine particles and oven dried. atsm
Air-Dried Procedure, Composite Sieving. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. Standards Subsctiption may be the perfect solution. This test method is used to separate particles into size ranges and to determine quantitatively the mass f6913 particles in each range. However, engineering behavior is dependent upon many factors such as effective stress, stress history, mineral type, structure, plasticity, and geologic origins and cannot be based solely upon gradation.
For specimens containing relatively small particles, the specimen is sieved in its entirety, using single sieve-set sieving. The quality of the result produced by these test methods is dependent on the competence of the personnel performing it, and the suitability atsm the equipment and facilities used. Depending on the design considerations, a specialized gradation-testing program could be performed. Dispersing and Washing 2 nd Subspecimen.
Selection of Sieving Procedure.
This method is only applicable for single sieve-set sieving and when the maximum particle size is equal to or less than the No. Oven-Dried Procedure, Composite Sieving.
It is assumed that the sample is obtained using appropriate methods and is representative.
For a single separation two portionsv6913 coarser portion is sieved in its entirety, while the finer portion is split into a smaller subspecimen for sieving. For cases of disputes, Method A is the referee method.
