Link to Active This link will always route to the current Active version of the standard. However, the use of balances or scales recording pounds of d6193 lbm shall not be regarded as nonconformance with this standard.
Subscription pricing is determined by: These data are combined to determine the particle-size distribution gradation. These results are mathematically combined. In addition, they are representative of the significant digits that generally should be retained. Typical examples x6913 these soils are some residual soils, most weathered shales and some weakly cemented soils such as hardpan, caliche or coquina.
ASTM D Standard
Composite D913, Double Separation. The material to be sieved will be placed on the coarsest sieve size of each sieve set and mechanically shaken. Soil testing Lab Services: Except, the sieve designations are typically identified using the “alternative” system in accordance with Practice E 11, such as 3 in. It is beyond the scope of these test methods to consider significant digits used in analysis methods for engineering design.
Separating 1 st Subspecimen. The methods differ in the significant digits recorded and the size of the specimen mass required. Please first verify your astmm before subscribing to alerts. This standard is not included in any packages. Dispersing and Washing 2 nd Subspecimen. Mortar and Rubber-Covered Pestle optional.
However, engineering behavior is dependent upon many factors such as effective stress, stress history, mineral type, structure, plasticity, and geologic origins dd6913 cannot be based solely upon gradation. The alterations could require the washing and sieving procedures to be standardized such that each specimen would be processed in a similar manner.

Using an Asttm Water Bath. This test method is used to separate particles into size ranges and to determine quantitatively the mass of particles in each range. Need more than one copy?
The methods differ in the significant digits recorded and the size of the specimen mass required. It is assumed that the sample is obtained using appropriate methods and is representative. The results will astn a tabulation of sieve sizes versus percent passing that can be graphically presented as a gradation curve a plot of the percent passing versus the log of the particle size in mm.
Finally, if the maximum asym size is equal to or greater d913 For specimens containing relatively small particles, the specimen is sieved in its entirety, using single sieve-set sieving. This test method is used to separate particles into size ranges and to determine quantitatively the mass of particles in each range. Percent Passing, Acceptance Criterion.
Specimen Procurement and Processing Requirements. The mass of particles retained on each sieve will be determined. For cases of disputes, Method A is the referee method. Furthermore, if the maximum particle size is greater than the 4.
Standards Subsctiption may be the perfect solution. Dry Sieving 2 nd Coarser Portion.
However, the specimen may contain a wide range of particle sizes and may require separating the soil asmt two, or three size ranges for more efficient sieving, using one or two designated separating sieve s.
