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. Depending on the design considerations, a specialized gradation-testing program could be performed.

Specimen Procurement and Processing Requirements. It is assumed that the sample is obtained using appropriate methods and is representative.

Adtm material to be sieved will be placed on the coarsest sieve size of each sieve set and mechanically shaken. This method is only applicable for single sieve-set sieving and when the maximum particle size is equal to or less than the No.

Subscription pricing is determined by: Low Temperature Drying Oven optional. This test method uses a square opening sieve criterion in determining the gradation of soil between the 3-in.

Subspecimen from Finer Portion. Percent Passing, 2 nd Subspecimen.

Using an Ultrasonic Water Bath. Need more than one copy? 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 standard does not purport to address all of the safety concerns, if any, associated d69133 its use. Samples from Prior Testing. Referenced Documents ast separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Only the SI units are used for asym determinations, calculations and reported results. This test method is used to determine the particle-size distribution gradation of a soil sample. Add to Alert PDF. The method to be used may be specified by the requesting authority; otherwise Method A shall be performed. This method must be used when performing composite sieving.

This method must be used when performing composite sieving. Dry Sieving 2 nd Coarser Portion. Mortar and Rubber-Covered Pestle optional. Large Mechanical Asm Shaker.

ASTM D Standard

Percent Passing, 2 nd Coarser Portion. The alterations could require the washing and sieving procedures to be standardized such that each specimen would be processed in a similar manner. It is beyond the scope of these test methods to consider significant digits used in analysis methods for engineering design. The method to be used may be specified by the requesting authority; otherwise Method A shall be performed. Soaking without a Dispersant. The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any d6931 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.

This test method uses a square opening sieve criterion in determining the gradation of soil between the 3-in.

The results will produce 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. 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.

Active Risk Management

Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors. Only the SI units are used for mass determinations, calculations, and reported results. This method is only applicable for single sieve-set sieving and when the maximum particle size is equal to or less than the No.

However, the applicable sections above should be used in ast this standard. Discussion on Segregating Soils. Furthermore, if the maximum particle size is greater than 4. Definitions of Terms Specific to This Standard. Splitter or Astj Box optional. Dispersing and Washing 2 nd Subspecimen. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.

This standard is not included in any packages. Typical examples of these soils are some residual soils, most weathered shales and some weakly cemented soils such as hardpan, caliche or coquina.
