标准范围

本国际标准规定了测量土壤团聚体稳定性的处理方法。信息技术适用于主要来自耕作土壤耕作层的各种材料。它可以，然而，也适用于任何土壤剖面层，无论其是否种植。骨料厚度为3毫米至5毫米的测量值。然而，在2 mm至5 mm的部分中存在砾石可能会扭曲结果。如果砾石的百分比在10%到40%之间，>；从试验中获得的2 mm部分砾石应进行清洗和处理平均加权直径（MWD，见6.1），在有砾石和无砾石的情况下计算。如果砾石的百分比为>；40%，结构稳定性试验不显著。该方法不适用于非结构化材料，因为它们的粘性不足以形成毫米级的骨料。

This International Standard specifies the treatments for the measurement of the stability of soil aggregates. Itcan be applied to a wide range of materials originating mainly from the tilled horizons of cultivated soils. It can,however, also apply to any soil profile horizon, whether it is cultivated or not. Aggregates ranging from 3 mmto 5 mm are measured.However, the presence of gravel in the 2 mm to 5 mm fraction can distort the results. If the percentage of gravelis between 10 % and 40 %, the > 2 mm fraction of the gravel obtained from the tests should be washed anda mean weighted diameter (MWD, see 6.1) calculated with and without gravel. If the percentage of gravel is> 40 %, the structural stability tests are not significant. The method does not apply to unstructured materials,as they are not sufficiently cohesive to form millimetric aggregates.
