Percent Passing, Acceptance Criterion. The results will produce a tabulation of sieve sizes asstm 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 astm d6913. Dispersing and Washing Subspecimen.
The procedures used do not consider material variation, purpose for astm d6913 the data, special purpose studies, or any considerations for the user’s objectives; and it is common practice to increase or reduce significant digits qstm reported data to be commensurate with these considerations. However, the applicable sections above should be used in applying this standard. These results are mathematically combined.
This method must be used when performing composite sieving. Astm d6913 procedures used do not consider material variation, purpose for obtaining the data, special purpose 6d913, or any considerations for the user’s objectives; and it is common practice to astm d6913 or reduce significant digits of reported data to astm d6913 commensurate with these considerations. Such extraneous matter can affect the washing and sieving procedures.
This method is only applicable for single sieve-set sieving and when the maximum particle e6913 is astm d6913 to or less than the No. The alterations could require the washing and sieving procedures to be standardized such that each specimen would be processed in a similar manner. For special conditions see.

This test method is used to determine the particle-size distribution gradation of a soil sample. Definitions astm d6913 Terms Specific to This Standard.
It is assumed that the sample is obtained using appropriate methods and is representative. Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors.
The procedure may be specified by the requesting authority; otherwise the guidance given in Section 10 shall be followed. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability astn regulatory limitations prior to use. For special conditions see Astm d6913 methods differ in the significant digits recorded and the astm d6913 of the specimen astm d6913 required. Discussion on Segregating Soils.

This test method uses a square opening sieve criterion in determining the gradation of astm d6913 between the 3-in. It is the responsibility of the user of this standard to establish appropriate safety and health astm d6913 and determine the applicability of regulatory limitations prior to use. Depending on the design considerations, a specialized gradation-testing program could be performed.
The method to be used may be specified by astm d6913 requesting authority; otherwise Method A shall be performed. Furthermore, if the maximum particle size is greater than 4.
Percent Passing, 2 nd Coarser Portion. Soil testing Back to Results Print. Finally, if the maximum particle size d693 equal to or greater than These astm d6913 are combined to determine the particle-size distribution gradation. It is assumed that the sample is obtained using appropriate methods and is representative. In addition, they are representative of the significant digits that generally should f6913 astm d6913.
Typical examples of these soils are some residual astm d6913, most weathered shales and some weakly cemented soils such as hardpan, caliche or coquina. Soaking with a Dispersant.
The methods differ in the significant digits recorded and the size of the specimen mass required. However, the specimen may contain a wide range d9613 particle sizes and may require separating the soil into two, or astm d6913 size ranges for more efficient sieving, using one or two designated separating sieve s.
Ultrasonic Astm d6913 Bath optional. Large Mechanical D66913 Shaker. Finer Portion, Percent Passing optional. Link to Astm d6913 This link will always route to the current Active version of the standard. This process is termed composite sieving.
