However, the applicable sections above should be used in applying this standard. Subscription pricing is determined by: However, engineering behavior is dependent upon many factors such as effective stress, stress history, mineral type, structure, plasticity, and geologic origins and d6193 be based solely upon gradation.

For a single separation two portionsthe coarser portion is sieved in its entirety, while the finer portion is split into a smaller subspecimen for sieving. 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.

This method must be used when performing composite sieving. However, the use of balances or scales recording pounds of mass lbm shall not be regarded as nonconformance with this standard.

It is the responsibility of ast user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. These results are mathematically combined. It is satm responsibility of the user of this standard to establish appropriate safety and 6d913 practices and determine the applicability of regulatory limitations prior to use.

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

ASTM D Standard

Finally, if the maximum particle size is equal to or greater than Finally, if the maximum particle size is equal to or greater than The methods differ in the significant digits recorded and the size of the specimen mass required. Users of these test methods are cautioned that compliance with Practice D does not in itself assure reliable results.

The method to be used may be specified by the requesting authority; otherwise Method A shall be performed. Definitions of Terms Specific to This Standard.

Composite Sieving, Mass of Specimen. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server. Subspecimen from Finer Portion.

Your Alert Profile lists the documents that will be monitored. Splitter or Riffle Box optional. Depending on the design considerations, a specialized gradation-testing program could be performed. The procedure may be specified by the requesting authority; otherwise the guidance given in Section shall be followed. Moist Procedure, Composite Sieving. Proceed to Checkout Continue Shopping. A representative specimen must be obtained from the sample by one of three procedures moist, air-dried or oven-dried.

The mass of particles retained on each sieve will be determined.

Mortar and Rubber-Covered Pestle optional. In addition, they are representative of the significant digits that generally should be retained.

Active Risk Management

Washing Sink with Spray Nozzle. Air-Dried Procedure, Composite Sieving. Composite Sieving, Single Separation. Referenced Documents purchase separately The documents listed below are referenced s6913 the subject standard but are not provided as part 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.

The alterations could require the washing and sieving procedures to be standardized such that each specimen would be processed in a similar manner. Depending on the design considerations, a specialized gradation-testing program could be performed.

Dispersing and Washing 2 nd Coarser Portion.

The methods differ in the significant digits recorded and the size of the specimen d9613 required.
