Standards Subsctiption may be the perfect solution. Prior to sieving, as applicable, the material will be washed to remove fine d6931 and oven dried. Subscription pricing is determined by: Such extraneous matter can affect the washing and sieving procedures. The alterations could require the washing and sieving procedures to be standardized such that each specimen would be processed in a similar manner.

Samples from Prior Testing. Percent Passing, 2 nd Subspecimen.

ASTM D6913

For special conditions see The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the user’s objectives; and it is common practice to increase or reduce significant digits of reported data to be commensurate with these considerations. Specimen Procurement and Processing Requirements.

Discussion on Segregating Soils. This method is only applicable for single sieve-set sieving and when the maximum particle size is equal to or less than the No. The method to be used may be specified by the requesting authority; otherwise Method A shall be performed. Finally, if the maximum particle size is equal to or greater than Active view current version of standard.

Finally, if the maximum particle size is equal to or greater than Composite Sieving, Double Separation.

Link to Active This link will always route to the current Active version of the standard. The alterations could require the washing and sieving procedures to be standardized such that each specimen would be processed in a similar manner. The material to be sieved will be placed on the coarsest sieve size of e6913 sieve set and mechanically shaken.

The procedure may be specified by the requesting authority; otherwise the guidance given in Section 10 shall be followed. It is assumed that the sample is obtained using appropriate methods and is representative. This test aetm is used to separate particles into size ranges and to determine quantitatively the mass of particles in each range.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Summary of Test Method. Percent Passing, Acceptance Criterion. Composite Sieving, Single Separation. As the voice of the U. Request Quote Client Login.

However, the applicable sections above should be used in applying this standard. Dispersing and Washing Subspecimen. Furthermore, if the maximum particle size is greater than 4. These data are combined to determine the particle-size distribution gradation.

The procedure selected will depend on the type of sample, d6931 maximum particle-size in the sample, the range of particle sizes, the initial conditions of the material, the plasticity of the material, the efficiency, and the need for other testing on the sample. Dry Sieving 2 nd Coarser Portion. Low Temperature Drying Oven optional.

Active Risk Management

Composite Sieving, Mass of Specimen. The procedure selected will depend on the type of sample, the maximum particle-size in the sample, the range of particle sizes, the initial conditions of the material, the plasticity of the material, the efficiency, and the need for other testing on the sample.

The procedure may be specified by the requesting authority; otherwise the guidance given in Section 10 shall be followed.

The method to be used may be specified by the requesting authority; otherwise Method A shall be performed. For cases of disputes, Method A is the referee method.

A representative specimen must be obtained from the sample by one of three procedures moist, air-dried or oven-dried. Large Mechanical Sieve Shaker. Soil testing Back to Results Print. For example, highway embankments, backfills, and earthen dams may have gradation requirements. D69113 testing Lab Services: However, the use of balances or scales recording pounds of mass lbm shall not be regarded as nonconformance with this standard.

ASTM D Standard

Definitions of Terms Specific to This Standard. 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. Reliable results depend on many factors; Practice D provides a means of aetm some of those factors. This test method is used to separate particles d6931 size ranges and to determine quantitatively the mass of particles in each range.

Hydraulic conductivity, compressibility, and shear strength are related to the gradation of the soil. Jar and Small Bag Samples.
