The standard gives guidance on techniques for taking and storing soil samples so that these can subsequently be examined for the purpose of providing information on soil quality.
This standard gives information on typical equipment that is applicable in particular sampling situations to enable correct sampling procedures to be carried out and representative samples to be collected. Guidance is given on the selection of the equipment and the techniques to use to enable both disturbed and undisturbed samples to be correctly taken at different depths.
The guidance provided is intended to assist in the collection of samples for soil quality for agricultural purposes and also provide guidance for the collection of samples for contamination investigations which will require different techniques and skills.
This standard makes reference to some aspects of the collection of samples of groundwater and soil gas as part of a soil sampling programme.
This standard specifically does not cover investigations for geotechnical purposes, though where redevelopment of a site is envisaged the soil quality investigation and the geotechnical investigation may be beneficially combined.
This standard is not applicable to the sampling of hard strata such as bedrock.
Techniques to collect information on soil quality without taking samples, such as geophysical methods, are not covered by this standard.

3 Terms and Definitions
For the purposes of this document, the terms and definitions in ISO 11074-1, ISO 11074-2, ISO 11074-4 and the following apply.
3.1 Spot Sample; Single Sample
sample of material collected from a single point
Note: This may be a disturbed or undisturbed sample.
3.2 Slot Sample
sample taken as a vertical slot from within a stratum or other subpart which is putatively homogeneous
Note: This is a disturbed sample.
3.3 Stratified Sample
sample obtained as a combination of spot samples from strata or subparts, putatively homogeneous
Note: This is a disturbed sample.
3.4 Cluster Sample
sample which is a composite of small incremental point samples taken close together
Note: This is a disturbed sample.
3.5 Spatial Sample
sample which is a composite of small incremental point samples taken over an area (such as a field)
Note: This is a disturbed sample.
