Standard Test Method for Materials Finer than 75-?m (No. 200) Sieve in Mineral Aggregates by Washing
N C117
Annotation
This test method covers the determination of the amount of material finer than a 75- m (No. 200) sieve in aggregate by washing. Clay particles and other aggregate particles that are dispersed by the wash water, as well as water-soluble materials, will be removed from the aggregate during the test.
Two procedures are included, one using only water for the washing operation, and the other including a wetting agent to assist the loosening of the material finer than the 75- m (No. 200) sieve from the coarser material. Unless otherwise specified, Procedure A (water only) shall be used.
The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard.
This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.

Метод стандартной пробы для материалов, более прекрасных, чем 75- m (№ 200) решето в минеральных совокупностях путем мытья
Этот метод тестирования покрывает определение суммы материала, более прекрасного, чем 75- m (№ 200) решето в агрегате путем промывки. Глиняные частицы и другие совокупные частицы, которые рассеиваются водой для мытья, а также растворимыми в воде материалами, будут удалены из агрегата во время теста.
