ISO DIS 18400-101

Description / Abstract: This International Standard specifies the procedural steps to be taken in the preparation and application of a sampling plan. The sampling plan describes the method of collection of the laboratory samples necessary for meeting the objective of the investigation programme. The principles or basic rules outlined in this International Standard provide a framework that can be used to:

— produce standardized sampling plans for use in more regular or routine circumstances;

— incorporate the specific requirements of national legislation;

— design and develop a sampling plan for use on a case by case basis.

This International Standard is applicable to sampling of soil and soil material, more specifically:

— soil in the landscape;

— soil stockpiles;

— potentially contaminated sites;

— agricultural soils;

— landfills;

— forest soils;

—

Ultimately the sampling plan provides the sampler with detailed instructions on how sampling should be carried out.

NOTE 1 There might be a need for more than one sampling plan to meet all the requirements of the investigation programme.

NOTE 2 When investigating a (potentially) contaminated site, it might sometimes be appropriate to divide the site into different zones on the basis of e.g. past use, future use, topography or geology, where for each zone a different sampling plan (or sub-sampling plan) is derived. Zoning might also be a helpful approach in order to focus the sampling.
