However, engineering behavior is dependent upon many factors such as effective stress, stress history, mineral type, structure, astm d6913, and geologic origins and cannot be based solely upon gradation.
Samples from Prior Testing. The method to be used may be specified by the requesting authority; otherwise Method A shall be performed. It is assumed that astm d6913 sample is obtained using appropriate methods and is representative. Composite Sieving, Mass of Specimen.
ASTM D Standard
The quality of the result produced by these astm d6913 methods is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. This method is only applicable for single sieve-set sieving and when the maximum particle size is equal to or less than astm d6913 No. However, the use of balances or scales recording pounds of mass lbm shall not be regarded as nonconformance astmm this standard. It is beyond the scope of these test methods to consider significant astm d6913 used in analysis methods for engineering design.
Percent Astm d6913, Acceptance Criterion. It is assumed that the sample is obtained using appropriate methods and is representative.
Jar and Small Bag Samples. Definitions of Terms Specific to This Standard. Using an Ultrasonic Water Bath. Prior to sieving, as applicable, the material will be washed to remove fine astm d6913 and oven dried.
Subspecimen from Finer Portion. Ultrasonic Water Bath optional. The procedure may be specified by the requesting authority; otherwise the guidance given in Section 10 shall be followed. It is beyond the scope of these test methods to consider significant digits used in analysis methods for engineering design. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations astm d6913 to use.
A representative specimen must be obtained from the astm d6913 by one of three procedures moist, air-dried or astm d6913. Such extraneous matter can affect the washing and sieving procedures. The methods differ in the significant digits recorded and the size of the specimen mass required.
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.
Discussion on Astm d6913 Soils. However, the applicable sections above should be used in applying this standard. This method is only astm d6913 for single sieve-set sieving and when the maximum particle size is equal to or less than the No.

The procedure selected will depend on the type of sample, the maximum particle-size in the sample, the range of particle sizes, the initial astm d6913 of the material, the plasticity of the material, the efficiency, and the need for other testing on the sample.
Only astm d6913 SI units are used for mass determinations, calculations, and reported results. Splitter or Riffle Box optional. 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. The alterations could require the washing and sieving procedures to be standardized such that each specimen would be processed in a similar manner.
Mortar astm d6913 Rubber-Covered Pestle optional.
Astm d6913 Mechanical Sieve Shaker. Moist Procedure, Composite Sieving. This test method is used to astm d6913 particles into size ranges and to determine astm d6913 the mass of d6193 in each range. Hydraulic conductivity, compressibility, and shear strength are related to the gradation of the soil. Soaking without a Dispersant. The results will produce a tabulation of astm d6913 sizes versus percent passing that can be asttm presented as a gradation curve a plot of the percent passing versus the log of the particle size in mm.
Soil testing Lab Services: Percent Passing, 2 nd Subspecimen. This test method uses a square opening sieve criterion in determining the gradation of soil between the 3-in.
For cases of disputes, Method A is the referee method. This test astm d6913 is used to determine the particle-size distribution gradation of a soil sample. Such extraneous matter can astm d6913 the washing and sieving procedures. These data are combined to determine the particle-size distribution gradation.

The methods differ in the significant digits recorded and the size of the specimen mass required. Percent Passing, Specimen combined coarser and finer astm d6913.
Typical examples of these soils are some residual soils, most weathered shales and some astm d6913 cemented soils such as hardpan, caliche or coquina.
These results are mathematically combined.
