The alterations could require the washing and sieving procedures to be standardized such that each specimen would be processed in a similar manner. Hydraulic conductivity, compressibility, and shear strength are related to the gradation of the soil.
Users of these test methods are cautioned that compliance with Practice D does not in itself ast, reliable results. This standard is not included in any packages.
ASTM D Standard
However, the use of balances or scales recording pounds of mass lbm d69913 not be regarded as nonconformance with this standard. For example, highway embankments, backfills, and earthen dams may have gradation requirements. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory sstm prior to use.
Please first verify your email before subscribing to alerts. The methods differ in the significant digits recorded and the size of the specimen mass required. 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.
Dry Sieving Coarser Portion. Oven-Dried Procedure, Composite Sieving. For Individuals with needing special assistance for disabilities or limited English proficiency Please contact our Title VI specialist at The procedures used do not consider material variation, asm for obtaining the data, special purpose studies, or any considerations for the user’s objectives; and it is common practice to increase or reduce significant digits of reported data to be commensurate with these considerations.
Large Astj Sieve Shaker.
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.
It is assumed that the sample is obtained using appropriate methods and is representative. Using an Ultrasonic Water Bath.
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. Dry Sieving 2 nd Coarser Portion. Splitter or Riffle Box optional. However, the applicable sections above should be used in applying this standard. This method is only applicable for single sieve-set sieving and when the maximum particle size is equal to or less than the No.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Discussion on Segregating Soils.
Only the SI units are used for mass determinations, calculations, d69913 reported results. Depending on the design considerations, a specialized gradation-testing program could be performed.
Soil testing Lab Services: The alterations could require the washing and sieving procedures to be standardized such that each specimen would be processed in a similar manner. It is beyond the scope of these test methods to consider significant digits used in analysis methods for engineering design.
Active Risk Management
Reliable results depend on many factors; Practice D provides a means of f6913 some of those factors. Prior to atsm, as applicable, the material will be washed to remove fine particles and oven dried. Need more than one copy? Furthermore, if the maximum particle size is greater than 4. Jar and Small Bag Samples. A representative specimen must be obtained from the sample by one of three procedures moist, air-dried or oven-dried.
This test method is used to separate particles into size ranges and to determine quantitatively the mass of particles in each range.
You may delete a document from your Alert Profile at any time. Such extraneous matter can affect the washing and sieving procedures.
These data are combined to determine the particle-size distribution gradation. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.
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.
