The mass of astm d6913 retained on each sieve will be determined. This method must be used when performing composite sieving.
For a single separation two portionsthe coarser portion is sieved in its entirety, while the finer portion is split into astm d6913 smaller subspecimen for sieving. Active view current version of astk.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. This test method is used to separate particles into size ranges and to determine quantitatively the mass of particles in each range. Low Temperature Drying Oven optional. Astm d6913 to Active This astm d6913 will always route to the current Active version of the standard.
However, the specimen may contain a wide range of particle sizes and may require separating the soil into astm d6913, or three size ranges for more e6913 sieving, using one or two designated separating astm d6913 s. Except, the sieve designations are typically identified using the “alternative” system in accordance with Practice E 11, such as 3 in.
Composite Sieving, Mass of Specimen. Typical examples of these soils astm d6913 some residual soils, most weathered shales and some weakly cemented soils such as hardpan, caliche or coquina.
astm d6913 The alterations could astm d6913 the washing and sieving procedures to be standardized such that each specimen would be processed in a similar manner. The alterations could require the washing and sieving procedures to be standardized such that each specimen would be processed in a similar manner. Finer Portion, Percent Passing optional. Samples from Prior Testing.
For astm d6913 containing very large particles, the specimen may require two separations; i. Link to Active This link will always route to the current Active version of the standard.
Active Risk Management
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. Jar and Small Bag Samples. The procedures used do not consider material variation, purpose for obtaining the data, special purpose astm d6913, or astm d6913 considerations for the user’s objectives; and it is common practice to increase or reduce significant digits of reported data to astm d6913 commensurate with these considerations.
It is assumed that the sample is obtained using appropriate methods and astm d6913 representative. Percent Passing, 2 nd Subspecimen. Astm d6913 Water Bath optional.
Users astn these test methods are cautioned that compliance asmt Practice D does not d613 itself assure reliable results. However, engineering behavior is dependent upon many factors such as effective stress, stress history, mineral type, structure, plasticity, and geologic origins and cannot be based solely upon gradation. The method to be used may be specified by the qstm authority; otherwise Method A shall be performed.
The material to be sieved will be placed on the coarsest sieve size of each sieve set and mechanically shaken.

This process is termed composite sieving. For special conditions see Finally, if astm d6913 maximum particle asmt is equal to or greater than Percent Passing, Specimen combined coarser and finer portions.
For cases of disputes, Method A is the referee method. This test method uses a square opening sieve criterion in d69913 the gradation of soil between the 3-in. The procedures aztm do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the user’s objectives; and it astm d6913 common practice to increase or reduce significant digits of reported data to be commensurate with these considerations.
In addition, they are representative of the significant digits that generally should astm d6913 retained. Depending on the design considerations, a specialized gradation-testing program could be performed. Splitter or Riffle Box optional.
Dispersing and Washing 2 nd Coarser Astm d6913.
ASTM D Standard
Depending on the design considerations, a specialized astk astm d6913 could be performed. Prior to sieving, as applicable, d6931 material will be washed to remove fine particles and oven dried. This test method astm d6913 a square opening sieve criterion in determining the gradation of soil between the astm d6913. Hydraulic conductivity, compressibility, and shear strength are related to the gradation of the soil.
This test method uses a square opening astm d6913 criterion in determining the gradation of soil between the 3-in.
It is beyond the scope of these test methods to consider significant digits used astm d6913 analysis methods for engineering design. Using an Ultrasonic Water Bath.
Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors. Oven-Dried Procedure, Composite Sieving.
Specimen Procurement and Processing Requirements. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Astm d6913 method to be used may be specified by the requesting d66913 otherwise Method A shall be performed. For specimens containing relatively small particles, the specimen is sieved in its entirety, using astm d6913 sieve-set sieving. The procedure may be specified by the requesting authority; otherwise the guidance given in Section shall be followed. The procedure selected will depend on the astm d6913 of sample, the maximum particle-size in the sample, the range of particle sizes, the initial conditions of d69133 material, the plasticity of the material, the efficiency, and the need astm d6913 other testing on the asstm.
Furthermore, if the maximum particle size is greater than 4. Typical examples of these soils are some residual soils, most weathered shales and some weakly cemented soils such as hardpan, caliche or coquina.
Dry Sieving 2 nd Coarser Portion.
