Full title and description

ISO 10406-2:2015 — Fibre-reinforced polymer (FRP) reinforcement of concrete — Test methods — Part 2: FRP sheets. This part of ISO 10406 specifies laboratory test methods and related procedures for FRP sheets and laminates used for externally bonded reinforcement and upgrading of concrete members.

Abstract

ISO 10406-2:2015 defines test methods applicable to FRP sheets (laminates) intended for strengthening or repairing concrete structures. The document covers characterization tests to assess mechanical properties, bond/adhesion behaviour and aspects of durability relevant to use of FRP sheets on concrete substrates. It was published as the second edition in 2015 and has subsequently been withdrawn and superseded by a 2025 edition.

Scope

This part of ISO 10406 specifies laboratory test methods for FRP sheets and laminates intended for externally bonded reinforcement of concrete members. The scope covers procedures for determining mechanical characteristics (e.g., tensile properties, modulus, ultimate strain), tests related to bonding/adhesion between FRP and concrete, and conditioning or auxiliary tests that inform durability assessments and acceptance criteria for strengthening applications. It is focused on material and test procedures rather than design rules or installation practice.

Key topics and requirements

• Definition and identification of FRP sheet/laminate properties relevant to concrete strengthening.
• Methods for determining tensile strength, stiffness (elastic modulus) and ultimate strain of laminates.
• Procedures for bond/adhesion testing between FRP sheets and concrete (pull-off, shear/bond tests and related specimen preparation).
• Requirements for specimen preparation, dimensions, and test conditions to ensure reproducible results.
• Guidance on conditioning and durability-related testing (environmental exposure, ageing) where appropriate for service-life assessment.
• Reporting requirements for test results, including statistical treatment and presentation of measured properties.

Typical use and users

Used by structural and materials engineers, testing and calibration laboratories, manufacturers of FRP sheets and composite strengthening systems, specification writers, and contractors involved in repair and strengthening of concrete structures. Typical uses include product characterization, quality control, acceptance testing of FRP strengthening systems, and providing test evidence for design and code compliance.

Related standards

Closely related documents include other parts of the ISO 10406 series (for example Part 1 covering FRP bars and grids), national and international test standards and guidelines for FRP-concrete bonding and laminate testing (commonly referenced test methods such as tensile and pull-off procedures from materials standards), and durability guidance and technical reports on long-term strength and ageing of reinforcement systems. Design codes and practice guides for FRP strengthening (national codes and technical recommendations) are typically used alongside this standard.

FAQ

Q: What is this standard?

A: ISO 10406-2:2015 is the ISO test-methods standard for fibre-reinforced polymer sheets used to strengthen or upgrade concrete members (externally bonded FRP laminates).

Q: What does it cover?

A: It covers laboratory procedures to measure key material properties (tensile strength, modulus, strain), bond/adhesion behaviour to concrete, specimen preparation and conditioning relevant to assessing performance and durability of FRP sheet systems. It does not provide design rules for structural strengthening.

Q: Who typically uses it?

A: Structural and materials engineers, test laboratories, FRP product manufacturers, specifiers and contractors who need standardized test procedures and repeatable data for product qualification, quality control and acceptance testing.

Q: Is it current or superseded?

A: This 2015 edition is withdrawn. It was superseded by a revised edition published in 2025 (ISO 10406-2:2025). The 2015 document should be treated as withdrawn and users should refer to the 2025 edition for the current requirements.

Q: Is it part of a series?

A: Yes — it is part of the ISO 10406 series on FRP reinforcement of concrete. Part 1 covers FRP bars and grids; Part 2 covers FRP sheets/laminates. Other related parts and national/international test and design documents may supplement the series.

Q: What are the key keywords?

A: FRP sheets, FRP laminates, externally bonded reinforcement, bond test, tensile properties, concrete strengthening, durability, ISO 10406.
