ISO 15630-3 Prestressing Steel Test Methods (Reinforcement & Prestressing of Concrete)

← Back to all standards

ISO 15630-3 is the test-methods standard for prestressing steel used in concrete structures, including bar, wire, and strand. To match this to your program, talk with our team.

What ISO 15630-3 Covers

It defines the tensile and related tests referenced by product specifications and project requirements when verifying prestressing steel.

How the Test Is Run

A prestressing bar, wire, or strand sample is gripped and pulled to failure, and tensile strength, proof stress, and elongation are recorded.

Why It Matters

Prestressing-steel verification underpins prestressed-concrete safety; strand grips or sockets and high-force capacity are essential.
