Overview
EN ISO 11074:2025 (ISO 11074:2025) is the third edition of the international vocabulary standard for soil quality. It defines and harmonizes terminology used across the field of soil quality and pedology. The 2025 edition consolidates terms into a single, alphabetically ordered Clause 3, clarifies context-dependent definitions (using domain tags in angle brackets), and incorporates the 2015 edition and the 2020 amendment it supersedes. The document was prepared by ISO/TC 190 in collaboration with CEN/TC 444 and includes an informative Annex A on relationships between sampling operations.
Key Topics and Requirements
- Comprehensive vocabulary: A single, centralized list of soil quality terms covering sampling, analysis, remediation, risk assessment and related concepts.
- Context differentiation: Terms that have different meanings in different contexts are grouped and labelled with the relevant domain (e.g., sampling, remediation).
- Alphabetical structure: All terms and definitions are placed in Clause 3 in alphabetical order for easier lookup.
- Practical entries: Definitions range from basic descriptors (e.g., aerobic, anaerobic) to procedural and analytical terms (e.g., analytical sample, above‑ground sampling, available water capacity).
- Supporting material: Annex A (informative) explains relationships between sampling operations; bibliography and index support further reference.
- No normative references: The standard contains no normative references, serving primarily as a reference vocabulary.
Practical Applications and Who Uses It
ISO 11074:2025 is intended for anyone who needs clear, consistent soil terminology across disciplines and jurisdictions:
- Environmental and geotechnical consultants preparing reports and sampling plans
- Soil scientists, pedologists and researchers conducting field and laboratory studies
- Accredited testing laboratories ensuring consistent sample descriptions and reporting
- Remediation contractors and project managers aligning remediation specifications
- Regulatory agencies and policymakers drafting guidance, permits and assessment criteria
- Standards writers and educators developing training materials or harmonized protocols
Practical uses include harmonizing contractual specifications, reducing ambiguity in site investigation reports, improving comparability of analytical results, and supporting environmental risk assessments.
