标准摘要
[中文适用范围]： 本文件描述了用于测试和在有争议的情况下确定骨料粒度分布的参考清洗和干筛方法。如果已与参考方法建立适当的工作关系，则可以使用其他方法。它适用于所有骨料，包括轻质骨料，公称尺寸最大为 90 毫米，但不包括填料。注：干筛不带清洗，可用于不含导致结块的颗粒的骨料。 [外文原描述]： This document describes the reference washing and dry sieving method used for testing and in case of dispute, for determination of the particle size distribution of aggregates. Other methods can be used provided that an appropriate working relationship with the reference method has been established. It applies to all aggregates, including lightweight aggregates, up to 90 mm nominal size, but excluding filler. NOTE: Dry sieving without washing can be used for aggregates free from particles which cause agglomeration.
