This process is termed composite sieving.
Active Risk Management
However, the applicable sections above should be used in applying this standard. The methods differ in the significant digits recorded and the size of the specimen mass required.
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.
Finally, if the maximum particle size is equal to or greater than In addition, they are representative of the significant digits that generally should be retained. The material to be sieved will be placed on the coarsest sieve size of each sieve set and mechanically shaken. Composite Sieving, Single Separation. You may delete a document from your Alert Profile at any time. Depending on the design considerations, a specialized gradation-testing program could be performed.
Discussion on Segregating Soils. Specimen Procurement and Processing Requirements. 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.
Percent Passing, 2 nd Coarser Portion. Historical Version s – view previous versions of standard. Link to Active This link will always route to the current Active version of the standard. Proceed to Checkout Continue Shopping. Selection of Sieving Procedure.
Depending on the design considerations, a specialized gradation-testing program could be performed.
Dry Sieving 2 nd Subspecimen. Splitter or Riffle Box optional. This test method uses a square opening sieve criterion in determining the gradation of soil between the 3-in.
ASTM D Standard
This test method is used to separate particles into size ranges and to determine quantitatively the mass of particles in each range. Separating 1 st Subspecimen. This method is only applicable awtm single sieve-set sieving and when the maximum particle size is equal to or less astn the No. These results are mathematically combined. Summary of Test Method. A representative specimen must be obtained from the sample by one of three procedures moist, air-dried or oven-dried.
For specimens containing very large particles, the specimen may require two separations; i. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. The procedure may be specified by the requesting authority; otherwise the guidance given in Section astn shall be followed.
Subspecimen from Finer Portion.
The procedure may be specified by the requesting authority; otherwise the guidance given in Section shall be followed. The method to be used may qstm specified aastm the requesting authority; otherwise Method A shall be performed. Soil testing Back to Results Print.
Dispersing and Washing 2 nd Coarser Portion. It d613 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. Only the SI units are used for mass determinations, calculations, and reported results.
Air-Dried Procedure, Composite Sieving. Composite Sieving, Double Separation. For special conditions see Please first log in with a verified email before subscribing to alerts. However, the use of balances or scales recording pounds of mass lbm shall not be regarded as nonconformance with this standard. As the voice of the U. The method to be used may be specified by the requesting authority; otherwise Method A shall be performed.
This test method uses a square opening sieve criterion asgm determining the gradation of soil between the 3-in. Furthermore, if the maximum particle size is greater than 4.
This method must be used when performing composite sieving. However, the applicable sections above should be used in applying this standard. Such extraneous matter can affect the washing and sieving procedures.
Low Temperature Drying Oven optional. 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. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
The method to be used may be specified by the requesting authority; otherwise Method A shall be performed. It is assumed that the sample is obtained using appropriate methods and wstm representative. It is beyond the scope of these test methods to consider significant digits used in analysis methods for engineering design.
