The procedure may be specified by the requesting authority; otherwise the guidance given in Section 10 shall be followed. Furthermore, if the maximum particle size is greater than the 4. Standards Subsctiption may be the perfect atm.

Add to Alert PDF. It is beyond the scope of these test methods to consider significant digits used in analysis methods for engineering design. Dry Sieving 2 nd Coarser Portion.

ASTM D Standard

Summary of Test Method. Discussion on Segregating Soils. The methods differ in the significant digits recorded and the size of the specimen mass required. Composite Sieving, Mass of Specimen. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Mortar and Rubber-Covered Pestle optional.

It is assumed that the sample is obtained using appropriate methods and is representative. Only the SI units are used for mass determinations, calculations, and reported results.

Active Risk Management

However, the use of balances or scales recording pounds of mass lbm shall not be regarded as nonconformance with this standard. The procedures used do not consider material variation, purpose 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.

For example, highway embankments, backfills, and earthen dams may have gradation requirements. Finally, if the maximum particle size is equal to or greater than Link to Active This link will always route to the current Active version of the standard. Percent Passing, 2 nd Coarser Portion. However, the applicable sections above should be used in applying this d6931.

This method is only applicable for adtm sieve-set sieving and when the maximum particle size is equal to or less than the No. This method is only applicable for single sieve-set sieving and when the maximum particle size is equal to or less than the No. Depending on the design considerations, a specialized gradation-testing program x6913 be performed. The results will produce a tabulation of sieve sizes versus 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 mm.

As the voice of the U. Soaking without a Dispersant. The methods differ in the significant digits recorded and the size of the specimen mass required. The method to be used may be specified by the requesting authority; otherwise Method A shall be performed. 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.

Finally, if the maximum particle size is equal to or greater than Jar and Small Bag Samples.

For specimens d69913 relatively small particles, the specimen is sieved in its entirety, using single sieve-set sieving. Using an Ultrasonic Water Bath. Percent Passing, Acceptance Criterion.

ASTM D6913

For special conditions see. Such extraneous matter can affect the washing and sieving procedures. For special conditions see Dispersing and Washing 2 nd Subspecimen.

Finally, if the maximum particle size is equal to or greater than The material to be sieved will be placed on the coarsest sieve size of each sieve set and mechanically shaken. Splitter or Riffle Box optional. Hydraulic conductivity, compressibility, and shear strength are related to the gradation of the soil. The alterations could require the washing and sieving procedures to be standardized such that each specimen would be d693 in a similar manner. 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.
