In addition, they are representative of the significant digits that generally should be retained.

Grain Size Distribution, Moisture-Density Tests, Atterberg Limits and Soil Classification Software

Typical examples of these soils are some residual soils, most weathered shales and some weakly cemented soils such as hardpan, caliche or coquina. Moist Procedure, Composite Sieving. However, the use of balances or scales recording pounds of mass lbm shall not be d6931 as nonconformance with this standard. These data are combined to determine the particle-size distribution gradation.

Percent Passing, Acceptance Criterion. 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.

This test method uses a square opening sieve criterion in determining the gradation of soil between the 3-in. Jar and Small Bag Samples.

Finer Portion, Percent Passing optional.

Using an Ultrasonic Water Bath. Such extraneous matter can affect the washing and sieving procedures. For cases of disputes, Method A is the referee method. This method must be used when performing aetm sieving.

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

Such extraneous matter can affect the washing and sieving procedures. For special conditions see The software can be set up to keep a list of IDs and weights for moisture content containers Selectively omit compaction test points from the moisture-density curve Moisture-density test results rounding are selectable on a per-test specification basis e.

Active view current version of standard.

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. Depending on the design considerations, a specialized gradation-testing program could be performed. For more information, contact: The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, ashm 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.

Soaking with a Dispersant. It is assumed that the sample is obtained using appropriate methods and is representative.

Dry Sieving 2 nd Subspecimen. LabSuite is site licensed. This test method is used to separate particles into size ranges and to xstm quantitatively the mass of particles in each range. Percent Passing, 2 nd Coarser Portion.

PDF files Raw testing data can be exported to XML files which can be imported into Excel The software features both submittal-quality chart reports and textural reports listing raw testing data. Users of these test methods are cautioned that compliance with Practice D does not in itself assure reliable results. Summary of Test Method.

Typical examples of these soils ast some residual soils, most weathered shales and some weakly cemented soils such as hardpan, caliche or coquina. This method is only applicable for single sieve-set sieving and when the maximum particle size is equal to or less than the No.
