The alterations could require the washing and sieving procedures to be standardized such that each atm would be processed in a similar manner. 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. Wstm is beyond the scope of these test methods to consider significant digits used in analysis methods for engineering design.

Furthermore, if the maximum particle size is greater than 4.

Ultrasonic Water Bath optional. Need more than one copy? The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the user’s objectives; awtm it is common practice to increase or reduce significant digits of reported data to be commensurate with these considerations.

The procedure may be specified by the requesting authority; otherwise the guidance given in Section 10 shall be followed. Active view current version of standard. Large Mechanical Sieve Shaker. This test method is used to separate particles into size ranges and to determine quantitatively the mass of particles in each range. It is assumed that the sample is obtained using appropriate methods and is representative.

However, the applicable sections above should be used in applying this standard.

This test method is used to determine the particle-size distribution gradation of a soil sample. Please d69913 verify your email before subscribing to alerts.

Typical examples of these soils are some residual soils, most weathered shales and some weakly cemented soils such as hardpan, caliche or coquina. The quality of the result produced by these test methods is dependent on the competence of the personnel performing it, asrm the suitability of the equipment and facilities used.

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 aastm, and the need for other testing on the sample. 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.

Air-Dried Procedure, Composite Sieving. Dispersing and Washing 2 nd Coarser Portion. Separating 1 st Subspecimen. The methods differ in the significant digits recorded and the size of the specimen mass required. For special conditions see For special conditions see.

Active Risk Management

This method is only applicable for single sieve-set sieving and when the maximum particle size is equal to awtm less than the No. Finer Portion, Percent Passing optional. The methods differ in the significant digits recorded and the size of the specimen mass required.

Splitter or Riffle Box optional. For Individuals with needing special assistance for disabilities or limited English proficiency Please contact our Title VI specialist at Link to Active This link will always route to the current Active version of the standard. Mortar and Rubber-Covered Pestle optional.

Depending on the design considerations, a specialized gradation-testing program could be performed. Soil testing Lab Services: However, the use of balances or scales recording pounds of mass lbm shall not be regarded as nonconformance with this standard. In addition, they are representative of the significant digits that generally should be retained.

It is assumed that the sample is obtained using appropriate methods and is representative. Percent Passing, Acceptance Criterion. Dispersing and Washing Subspecimen.

The procedures used do not consider material variation, purpose sstm 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.

Users of these test methods are cautioned that compliance with Practice D does not in itself assure reliable results. Add to Alert PDF.
