3. Terminology
3. 1 !)efinitions—For definitions of terms used in this standard, refer to Terminology (‘125.
4. Summary of Test Method
4.1 A sample of dry aggregate of known mass is separated through a series of sieves of progressively smaller openings for determination of particle size distribution.
5. Significance and Use
5.1 This test method is used primarily to determine the grading of materials proposed for use as aggregates or being used as aggregates. The results are used to determine compliance of the particle size distribution with applicable specification requirements and to provide necessary data for control of the production of various aggregate products and mixtures containing aggregates. The data may also he useful in developing relationships concerning porosity and packing.
5.2 Accurate determination of material liner than the 75-um (No. 200) sieve cannot be achieved by use of this test method alone. Test Method (‘117 for material finer than 75-um sieve by washing should be employed.
6. Apparatus
6.1 Balances—Balances or scales used in testing tine and coarse aggregate shall have readability and accuracy as follows:
6.1.1 For tine aggregate, readable to 0.1 g and accurate to
0.1 g or 0.1 % of (he test load, whichever is greater. at any point within (he range of use.
6.1.2 For coarse aggregate, or mixtures of fine and coarse aggregate, readable and accurate to 0.5 g or 0.1 % of the test load, whichever is greater, at any point within the range of use.
6.2 Sieves—The sieve cloth shall be mounted on substantial frames Constructed in a manner that will prevent loss of material during sieving. The. sieve cloth and standard sieve frames shall conform to the requirements of Specification El 1. Nonstandard sieve frames shall conform to the requirements of Specification El I as applicable.
