Soil quality - Measurement of the stability of soil aggregates subjected to the action of water

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.

Soil quality - Measurement of the stability of soil aggregates subjected to the action of water

This International Standard specifies the treatments for the measurement of the stability of soil aggregates. It

can 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 mm

to 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 gravel

is between 10 % and 40 %, the > 2 mm fraction of the gravel obtained from the tests should be washed and

a 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.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
