Dispersing and Washing 2 nd Coarser Portion. However, the applicable sections above should be used in applying this standard. Percent Passing, 2 astn Subspecimen.

This standard is also available to be included in Standards Subscriptions. Only the SI units are used for mass determinations, calculations, and reported results.

Hydraulic conductivity, compressibility, and shear strength are related to the gradation of the soil. Prior to sieving, as applicable, the material will be washed to remove fine particles and oven dried. This test method is used to separate particles into size ranges and asttm determine quantitatively the mass of particles in each range.

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. Mortar and Rubber-Covered D69113 optional. C6913 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.

If the document is revised or amended, you will be notified by email.

Composite Sieving, Mass of Specimen. For cases of disputes, Method A is the referee method. The methods differ in the significant digits recorded and the size of the specimen mass required. Selection of Sieving Procedure. Finally, if the maximum particle size is equal to or greater than This method is only applicable for single sieve-set sieving and when the maximum particle size is equal to or less than the No.

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.

These data are combined to determine the particle-size distribution gradation. Furthermore, if the maximum particle size is greater than 4.

ASTM D Standard

This method is only applicable for single sieve-set sieving and when the maximum particle size is equal to or less than the No. In addition, they are representative of the significant digits that generally should be retained.

However, the specimen may contain a wide range of d69133 sizes and may require separating the soil into two, or three size ranges for axtm efficient sieving, using one or two designated separating sieve s. 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 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.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Finally, if the maximum particle size is equal to or greater than It is assumed that the sample is obtained using appropriate methods and is representative. For specimens containing very large particles, the specimen may require two separations; i. The methods differ in the significant digits recorded and the size of the specimen mass required. Composite Sieving, Double Separation.

The quality of the result produced by these test methods is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. This method must be used when performing composite sieving. The method to be used may be specified by the requesting authority; otherwise Method A shall be performed.

Jar and Small Bag Samples. 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. Soaking without a Dispersant.

Active Risk Management

Users of these test methods are cautioned that compliance with Practice D does not in itself assure reliable atsm. Percent Passing, Acceptance Criterion. The methods differ in the significant digits recorded and the size of the specimen mass required.

Historical Version s – view previous versions of standard. It is beyond the scope of these test methods to consider significant digits used atsm analysis methods for engineering design. Splitter or Riffle Box optional.

Typical examples of these soils are some residual soils, most weathered shales and some weakly cemented soils such as hardpan, caliche or coquina. Dry Sieving 2 nd Coarser Portion.

Definitions of Terms Specific to This Standard. Your Alert Profile lists the documents that will be monitored.

Soil testing Back to Results Print. This test method uses a square opening sieve criterion in determining the gradation of soil between the 3-in.
