The methods differ in the significant digits recorded and the size of the specimen mass required. Referenced Ashm purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Jar and Small Bag Samples. It is beyond the scope of these test methods to consider significant digits used in analysis methods for engineering design. Soaking with a Dispersant.

The alterations could require the washing and sieving procedures to be standardized such that each specimen would be processed in a similar manner.

ASTM D6913

However, the applicable sections above should be used in applying this standard. For specimens containing relatively small particles, the specimen is sieved in its entirety, using single sieve-set sieving.

In addition, they are representative of the significant digits that generally should be retained. Furthermore, if the maximum particle size is greater than 4.

Such extraneous matter can affect the washing and sieving procedures. Only the SI units are used for mass determinations, calculations and reported results.

ASTM D Standard

D613, the applicable sections above should be used in applying this standard. The methods axtm in the significant digits recorded and the size of the specimen mass required. However, the specimen may contain a wide range of particle sizes and may require separating the soil into two, or three size d66913 for more efficient sieving, using one or two designated separating sieve s.

Dry Sieving 2 nd Subspecimen. The results will produce a tabulation of sieve sizes versus percent passing that can be graphically presented as a gradation curve a astk of the percent passing versus the log of the particle size in mm.

The software can be set up to keep a list of IDs and weights for moisture content containers Selectively omit compaction test points from the moisture-density curve Moisture-density test results rounding are selectable on a per-test specification basis e.

Multiple report chart report formats are available for reporting particle size, Proctor and Atterberg test results. Typical examples of these soils are some residual soils, most weathered shales and some weakly cemented soils such as hardpan, caliche or coquina.

Percent Passing, 2 nd Subspecimen. For special conditions see. The material to be sieved will be placed on the coarsest sieve size of each sieve set and mechanically shaken. R6913 mass of particles retained on each sieve will be determined. For special conditions see This standard does not purport to address all atsm the safety concerns, if any, associated with its use.

Historical Version s – view previous versions of standard. Finally, if the maximum particle size is equal to or greater than Only the SI ashm are used for mass determinations, calculations, and reported results. Asm Quote Client Login. 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.

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 procedure may be specified by the requesting authority; otherwise the guidance given in Section 10 shall be followed. Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors.

Composite Sieving, Double Separation. For more information, contact: Such extraneous matter can affect the washing and sieving procedures. Composite Sieving, Single Separation. It is assumed that the sample d69113 obtained using appropriate methods and is representative.

Prior to sieving, as applicable, the material will be washed to remove fine particles and oven dried. It is beyond the scope of these test methods to consider significant digits used in analysis methods for engineering design.

For specimens containing very large particles, the specimen may require two separations; i. Soil testing Lab Services: This test method uses a square opening sieve criterion in determining the gradation of soil between the 3-in.

Large Mechanical Sieve Shaker. Look at some sample Atterberg limits test reports.

Selection of Sieving Procedure. For a single separation two portionsthe coarser portion is sieved in its entirety, while the finer portion is split into a smaller subspecimen for sieving.

Composite Sieving, Mass of Specimen. Depending on the design considerations, a specialized gradation-testing program could be performed.

Dispersing and Washing 2 nd Coarser Portion.
