For cases of disputes, Method A is the referee method. Referenced Documents purchase separately The documents listed below are d691 within the subject standard but are not provided as part of the standard. For example, highway embankments, backfills, and earthen dams may have gradation requirements. The methods differ in the significant digits recorded and the size of the specimen mass required. This test method uses a square opening sieve criterion in determining the gradation of soil between the 3-in.
As the voice of the U. In addition, they are representative of the significant digits that generally should be retained. You can sstm and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.
Jar and Small Bag Samples. 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.
ASTM D Standard
Using an Ultrasonic Water Bath. Separating 1 st Subspecimen. For special conditions see.
This method is only applicable for single sieve-set sieving and when the maximum particle size is equal to or less than the No. Furthermore, if the maximum particle size is greater than 4.
Dispersing and Washing 2 xstm Coarser Portion. Air-Dried Procedure, Composite Sieving. 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.
This standard does not purport to address all of the safety concerns, if any, associated with its use. The procedure may be specified by the requesting authority; otherwise the guidance given in Section shall be followed.
The procedure may be specified by the requesting authority; otherwise the guidance given in Section 10 shall be followed. Such extraneous matter can affect the washing and sieving procedures.
Historical Version s – view previous versions of standard. Prior to sieving, as applicable, the material will be washed to remove fine particles and oven dried. Dry Sieving 2 nd Subspecimen.
This method must be used when performing composite sieving. This test method is used asstm determine the particle-size distribution gradation of a soil sample. 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.
Active Risk Management
Hand Sieve Shaking Procedure. However, the use of balances or scales recording pounds of mass lbm shall not be regarded as nonconformance with this standard. For cases of disputes, Method A is the referee method.
Ultrasonic Water Bath optional. However, the applicable sections above should be used in applying this standard. Furthermore, if the maximum particle size is greater than the 4.
These data are combined to determine the particle-size distribution gradation. It is beyond the scope of these test methods to consider significant digits used in analysis methods for engineering design. Only the SI units are used for mass determinations, calculations and reported results. Samples from Prior Testing. Depending on the design considerations, a specialized gradation-testing program could be performed. Active view current version of standard.

For Individuals with needing special assistance for disabilities or limited English proficiency Please contact our Title VI specialist at The mass of particles retained on each sieve will be determined.
Moist Procedure, Composite Sieving. Composite Sieving, Single Separation. The method to be used may be specified by the requesting authority; otherwise Method A shall be performed. The alterations could require the washing and sieving procedures to be standardized such that asrm specimen would be processed in a similar asmt.
