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 procedure selected will depend on aztm 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.

Finally, if the maximum particle size is equal to or greater than Soaking without a Dispersant. Standards Subscriptions asgm ANSI provides a money-saving, multi-user solution for accessing standards. Link to Active This link will always route to the current Active version of the standard. The procedure may be specified by the requesting authority; otherwise the guidance given in Section 10 shall be followed.

However, the use of balances or scales recording pounds of mass lbm shall not be regarded as nonconformance with this standard. Only the SI units are used for mass determinations, calculations and reported results. The mass of particles retained on each sieve will be determined. It is beyond the scope of these test methods to consider significant digits used in analysis methods for engineering design.

Historical Version s – view previous versions of standard. Soaking with a Dispersant. This method is only qstm for single sieve-set sieving and when the maximum particle size is equal to or asrm than the No.

Separating 1 st Subspecimen. However, the specimen may contain a wide range of particle sizes and may require separating the soil into two, or three size ranges for more efficient sieving, using one or two designated separating sieve s. The methods differ in the significant digits recorded and the size of the specimen mass required. 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.

Add to Alert PDF. A representative specimen must be obtained from the sample by one of three procedures moist, air-dried or oven-dried. Finally, if the maximum particle size is equal to or greater than Selection of Sieving Procedure. Typical examples of these soils are some residual soils, most weathered shales and some weakly cemented soils such as hardpan, caliche or coquina.

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. Finally, if the maximum particle size is equal to or greater than Already Subscribed to this document. Washing Sink with Spray Nozzle. Air-Dried Procedure, Composite Sieving. If the document is revised or amended, you will be notified by email.

The material to be sieved will be placed on the coarsest sieve size of each sieve set and mechanically shaken.

Percent Passing, 2 nd Coarser Portion. This method must be used when performing composite sieving. Typical examples of these soils are some residual soils, most weathered shales and some weakly cemented d693 such as hardpan, caliche or coquina.

The alterations could require the washing and sieving procedures to be standardized such that each specimen would be processed in a similar manner. Soil testing Lab Services: However, the applicable sections above should be used in applying this standard.
