Overview

EN ISO 9862:2023/prA1:2025 - Amendment 1 updates ISO 9862 (Geosynthetics - Sampling and preparation of test specimens) to add specific sample‑preparation requirements for Geosynthetic Cementitious Composites (GCCs). Prepared by ISO/TC 221 (secretariat: BSI) and processed in the ISO/CEN parallel workflow, this amendment clarifies terminology, cutting margins, and references established practices for preparing hydrated and cured GCC test specimens.

Key topics and requirements

• New normative reference
  • Adds ASTM D8030/D8030M‑24 as a normative reference for GCC specimen preparation.
• Defined terms
  • Introduces clear definitions for cured, uncured, and hydrated as they apply to GCCs (i.e., states before and after hydration/initial hardening).
• Specimen cutting requirement
  • For GCC specimens that will be tested in a hydrated (wet) or cured (wetted and hardened) state, the amendment requires cutting from uncured samples that are oversized by not less than 25 mm on each side of the specimen perimeter.
  • The amendment includes a template/figure showing test specimen markings within a 25 mm perimeter margin.
• Preparation cross‑reference
  • Adds clause directing laboratories to refer to ASTM D8030/D8030M for detailed procedures when preparing hydrated and cured GCC specimens.

Applications and who uses it

This amendment is practical for professionals and organizations involved in geosynthetics testing, quality control, and construction materials research:

• Geosynthetic and GCC manufacturers - to ensure representative sampling and consistent specimen preparation during product development and QA.
• Independent testing laboratories - to align sample preparation with international practice and to ensure valid, reproducible test results for hydrated/cured GCCs.
• Civil and geotechnical engineers - when specifying test methods and acceptance criteria for GCC products used in soil stabilization, erosion control, or containment systems.
• Standards committees and regulators - to reference harmonized sampling and preparation rules in specifications or conformity assessments.

Related standards and keywords

• Related normative reference: ASTM D8030/D8030M‑24 (Sample Preparation for GCCM)
• Keywords for search and SEO: geosynthetics, Geosynthetic Cementitious Composites, GCC, sample preparation, specimen cutting, ISO 9862, ASTM D8030, hydrated specimens, cured specimens, testing, quality assurance.

This amendment helps standardize how GCC test specimens are obtained and prepared, improving comparability of test data across labs and projects.
