Full title and description

ISO 10406-2:2025 — Fibre‑reinforced polymer (FRP) reinforcement of concrete — Test methods — Part 2: FRP sheets. This edition (2025) defines standardized laboratory test methods for characterizing FRP sheets used to upgrade or strengthen concrete members, including mechanical, bond and durability test procedures intended for procurement, conformity assessment and research.

Abstract

This document specifies test methods applicable to fibre‑reinforced polymer (FRP) sheets for the upgrading of concrete members. It provides procedures to determine relevant properties of FRP sheets (e.g., tensile and shear behaviour, bond to substrate, and selected conditioning/durability tests) so results are repeatable and comparable between laboratories.

Scope

ISO 10406-2:2025 covers standardized test methods for FRP sheets used to reinforce or upgrade concrete structures. The scope includes procedures for determining mechanical properties (tensile strength, elastic modulus, elongation), bond performance between sheet and concrete or adhesive, and selected durability/conditioning tests relevant to long‑term performance. It is intended for use by testing laboratories, manufacturers, specifiers and researchers involved in FRP strengthening of concrete.

Key topics and requirements

• Definitions and specimen preparation requirements for FRP sheet testing.
• Tensile testing procedures to determine strength, stiffness and ultimate strain.
• Bond test methods for sheet-to-substrate systems (including adhesive-bonded configurations).
• Shear and interlaminar test methods where applicable to sheet systems.
• Conditioning and durability test procedures (environmental exposure, accelerated aging) and reporting of conditioned results.
• Required test reporting items: test setup, specimen geometry, conditioning history, measured values and uncertainty information.

Typical use and users

Typical users are standards committees, testing and research laboratories, manufacturers of FRP sheets and adhesives, structural engineers specifying or verifying FRP strengthening for concrete members, and procurement/specification authors. The standard is used for product qualification, comparative testing, contract specifications and research studies on FRP retrofit systems.

Related standards

ISO 10406-2:2025 is part of the ISO 10406 series on FRP reinforcement of concrete and updates earlier editions (2008, 2015). It is complemented by other parts in the series and by national/sector standards for design and application of FRP reinforcement, test methods for FRP bars/plates and general structural testing standards referenced within its text.
