This test method uses a square opening sieve criterion in determining the gradation of soil between the 3-in. This test method is used to separate particles into size ranges and to determine quantitatively the mass of particles in each range.
Except, the sieve designations are typically identified using the “alternative” system in accordance with Practice E 11, such as 3 in. For specimens containing very large particles, the specimen may require two separations; i. In addition, they are representative of the significant digits that generally should be retained.
ASTM D Standard
The procedure may be specified by the requesting authority; otherwise the guidance given in Section 10 shall be followed. It is assumed that the sample is obtained using appropriate methods and is representative. Soil testing Back to Results Print. 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.
For special conditions see. Users of these test methods are cautioned that compliance with Practice D does not in itself assure reliable asgm. For cases of disputes, Method A is the referee method. This method is only applicable for single sieve-set sieving and when the maximum particle size is equal to or less than the No.
Standards Subsctiption may be the perfect solution. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors.

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 use of balances or scales recording pounds of mass lbm shall not be regarded as nonconformance with this standard. Only the SI units are used for mass determinations, calculations and reported results. These results are mathematically combined. Furthermore, if the maximum particle size is greater than 4.
The method to be used may be specified by the requesting authority; otherwise Method A shall be performed. Composite Sieving, Single Separation. 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.
Furthermore, if the maximum particle size is greater than 4.
For example, highway embankments, backfills, and earthen dams may have gradation requirements. Dispersing and Washing 2 nd Coarser Portion. If the document is revised or amended, you will be notified by email.
Finally, if the maximum particle size is equal to or greater than The alterations could require the washing and sieving procedures to be standardized such that each specimen would be processed in a similar manner. Furthermore, if the maximum particle size is greater than the 4. This method must be used f6913 performing composite sieving. Separating 1 st Subspecimen. Please first verify your email before subscribing to alerts.
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. This standard is also available to be included in Standards Subscriptions.
The method to be used may be specified by the requesting authority; otherwise Method A shall be performed.
Finer Portion, Percent Passing optional. Such extraneous matter can affect the washing and sieving procedures. In addition, they are representative of the significant digits that generally should be retained. Finally, if the maximum particle size is equal to or aztm than These data are combined to determine the particle-size distribution gradation.
The procedure may be specified by the requesting authority; otherwise the guidance given in Section shall be followed. It is e6913 that the sample is obtained using appropriate methods and is representative. Dispersing and Washing Subspecimen.
