Samples from Prior Testing. Percent Passing, 2 nd Coarser Portion. Mortar and Rubber-Covered Pestle optional. Subscription pricing is determined by: Finally, if the maximum particle size is equal to or greater than Dispersing and Washing Subspecimen. However, the use of balances or scales recording pounds of mass lbm shall not be regarded as nonconformance with this standard.
Prior to sieving, as applicable, the material will be washed to remove fine particles and oven dried. For Individuals with needing special assistance for disabilities or limited English proficiency Please contact our Title VI specialist at For more information, contact: This standard does not purport to address all of the safety concerns, if any, associated with its use. Selection of Sieving Procedure. This method is only applicable ast single sieve-set sieving and when the maximum particle size is equal to or less than the No.
Large Atm Sieve Shaker. This test method is used to determine the particle-size distribution gradation of a soil sample.
The procedure may be specified by the requesting authority; otherwise the guidance given in Section 10 shall be followed.
Dry Sieving 2 nd Coarser Portion. This test method uses a square opening sieve criterion in determining the gradation of soil between the 3-in.
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. Typical examples of these soils are some residual soils, most weathered shales and some weakly cemented soils such as hardpan, caliche or coquina.
In addition, they are representative of the significant digits that generally should be retained. Soaking with a Dispersant. However, the applicable sections above should be used in applying this standard. 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.
A representative specimen must be obtained from the sample by one of three procedures moist, air-dried or oven-dried. The procedure selected astk 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 s6913 the material, the efficiency, and the need for other testing on the sample. Such extraneous matter can 6d913 the washing and sieving procedures.
Active view current version of standard. This test method is used to separate particles into size ranges and to determine quantitatively the mass of particles in each range. Standards Subsctiption may be the perfect solution.
For cases of disputes, Method A is the referee method. Furthermore, if the maximum particle size is greater than 4. It is assumed that the sample is obtained using appropriate methods xstm is representative. 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.

The alterations could require the washing and sieving procedures to be standardized such that each specimen would be processed in a similar manner.

These data are combined to determine the particle-size distribution gradation.
