Full title and description

ISO 10381-8:2006 (corrected 2007) — Soil quality — Sampling — Part 8: Guidance on sampling of stockpiles. This part of ISO 10381 gives guidance for planning and performing sampling of soil material held in stockpiles (the solid phase), including design of sampling plans, choice of sampling strategies and techniques, field subsampling, sample handling (packing, preservation, storage, transport) and documentation.

Abstract

ISO 10381-8 provides practical guidance to obtain representative samples from soil stockpiles for subsequent analysis. It covers the principles of sampling, statistical considerations, detailed sampling strategies (probabilistic and judgemental), specific sampling techniques, in-field pretreatment and subsampling methods and requirements for packaging, preservation and transport of samples. Informative annexes describe sampling equipment and subsampling procedures.

Scope

This document gives guidance on how to design and carry out sampling of soil stockpiles so that samples collected are appropriate for the intended analyses and decisions. It addresses formulation of a sampling plan, selection of sampling strategies (including statistical design), sampling techniques for different pile types and materials, field subsampling and pretreatment, and procedures for packing, preserving, storing and transporting samples, together with recording requirements and health & safety considerations. It is limited to sampling of the solid soil phase held in stockpiles and does not prescribe laboratory test methods.

Key topics and requirements

• Definition and documentation of a sampling plan that reflects the sampling purpose and primary/secondary goals.
• Guidance on sampling strategies: probabilistic (random, stratified, systematic) and judgemental approaches, with discussion of statistical principles.
• Recommended sampling techniques for stockpiles (spot, directional, systematic approaches) and selection criteria depending on material type and consolidation.
• Field subsampling and pretreatment methods (coning and quartering, riffling, use of dividers) and annexed procedures for representative subsamples.
• Descriptions of common sampling equipment (augers, sampling tubes, scoops, shovels, mechanical devices) and practical notes on their use.
• Requirements for sample identification, packaging, preservation, storage, transport and delivery to ensure sample integrity and chain-of-custody.
• Health and safety considerations for field sampling operations.

Typical use and users

Used by environmental consultants, site investigators, laboratories, contractors, landfill and construction site managers and regulators who need to sample soil materials from stockpiles for contamination assessment, quality control, acceptance testing or research. The guidance helps sampling personnel, project managers and quality managers design sampling plans and perform field work that produces representative, documented samples for laboratory analysis.

Related standards

ISO 10381-8 formed part of the ISO 10381 series on soil sampling. It has been withdrawn and related/replacing work in the ISO soil sampling family and more recent ISO standards (including parts of the ISO 18400 series) provide updated guidance on sampling of soils and materials. Users should consult the current ISO soil sampling documents and national/adopted versions for the latest, active requirements.

FAQ

Q: What is this standard?

A: ISO 10381-8:2006 is an ISO guidance standard titled "Soil quality — Sampling — Part 8: Guidance on sampling of stockpiles" that provides practical instructions for sampling soil material from stockpiles.

Q: What does it cover?

A: It covers preparation of a sampling plan, selection of sampling strategies and techniques, field subsampling and pretreatment, descriptions of sampling equipment, and requirements for packing, preservation, storage, transport and documentation of samples. It is focused on sampling the solid soil phase from stockpiles and does not specify laboratory test methods.

Q: Who typically uses it?

A: Environmental consultants, site investigation teams, laboratories, construction and waste management contractors, regulators and anyone responsible for collecting representative soil samples from stockpiles for analysis or acceptance testing.

Q: Is it current or superseded?

A: ISO 10381-8:2006 has been withdrawn. Users should refer to the current ISO soil-sampling publications (including later ISO 18400-series documents and any national adoptions) for up-to-date guidance. National standards bodies (for example the BSI) list the withdrawal and replacement information for this part.

Q: Is it part of a series?

A: Yes — it was part of the ISO 10381 series on soil sampling (multiple parts covering different sampling contexts). The ISO 10381 series and related ISO soil-quality standards provide complementary guidance on sampling soils for environmental and quality assessments.

Q: What are the key keywords?

A: Soil sampling, stockpile sampling, sampling plan, subsampling, sample preservation, sampling equipment, soil quality, coning and quartering, riffling.
