Full title and description

Fibre-reinforced polymer (FRP) reinforcement of concrete — Test methods — Part 1: FRP bars. This International Standard specifies test methods applicable to FRP bars used as reinforcement or pre-stressing tendons in concrete, covering physical, mechanical, durability and long‑term property assessments.

Abstract

ISO 10406-1:2025 defines standardized laboratory test methods for FRP bars made from fibres (aramid, basalt, carbon or glass) and polymeric matrices (thermosetting and thermoplastic resins). It addresses the determination of physical characteristics, mechanical performance, bond behaviour and durability / long‑term behaviour so that manufacturers, testing bodies and designers can obtain comparable, repeatable results.

Scope

ISO 10406-1:2025 specifies test procedures for evaluating FRP bars when used as reinforcement or pre‑stressing tendons in concrete. The scope includes test methods for physical properties (dimensions, density), mechanical properties (tensile strength, modulus, flexural behaviour), bond behaviour with concrete, durability exposures (alkali, moisture, temperature, UV and other ageing conditions as applicable) and long‑term performance (creep, fatigue and sustained‑load performance). The standard applies to FRP bars composed of a fibre reinforcement and a resin matrix (thermoset and thermoplastic).

Key topics and requirements

• Specified laboratory test methods for physical characterization (dimensions, cross‑sectional properties, density).
• Mechanical performance tests including tensile strength, elastic (Young's) modulus and flexural behaviour.
• Bond testing procedures to assess interaction between FRP bars and concrete (pull‑out / bond strength evaluations).
• Durability and ageing tests covering alkaline exposure, wet/dry cycling, elevated temperature, UV and other environmental conditions relevant to concrete structures.
• Long‑term properties: creep and fatigue test methods and reporting for sustained load behaviour.
• Requirements for specimen preparation, conditioning, test speeds/loads, data recording and reporting to ensure repeatability and comparability.

These topic summaries reflect the standard's coverage of physical, mechanical, durability and long‑term test methods for FRP bars.

Typical use and users

Primary users include materials and structural testing laboratories, FRP bar manufacturers, civil/structural engineers, standards bodies and research organizations involved in concrete reinforcement and rehabilitation. The standard is used to generate manufacturer declarations, to qualify products for design use, and as a reference in design codes and technical specifications for FRP reinforcement.

Related standards

ISO 10406 is a multi‑part series addressing different FRP reinforcement forms. Related parts published in 2025 include ISO 10406‑2 (FRP sheets) and ISO 10406‑4 (FRP grids), which define test methods appropriate to those product types; earlier editions (for example ISO 10406‑1:2015) have been withdrawn and superseded by the 2025 publications.
