Full title and description

ISO 10287:1992 — Steel for the reinforcement of concrete — Determination of strength of joints in welded fabric. Specifies a laboratory test method to determine the tensile strength of welded joints in steel welded fabric used for concrete reinforcement.

Abstract

This International Standard defines a test procedure for extracting and testing specimens from welded fabric reinforcement to measure the maximum force at which a welded joint fails and to record the location and mode of fracture. The method addresses specimen placement, support of the pulling wire, loading rate limits and the recording of results; it is intended for use in quality control and comparative testing of welded fabric joints.

Scope

Applies to welded fabric (factory-made welded meshes) for the reinforcement of concrete and specifies a tensile test procedure for determining the strength of individual welded joints. The standard covers specimen preparation and positioning, the required support to prevent bending of the pulling wire, permissible loading rate (stress increase) during the test, and the recording of maximum force and fracture location. It is a method standard — it does not itself set acceptance limits for product performance.

Key topics and requirements

• Definition and selection of test specimens taken from welded fabric.
• Fixtures and support arrangements to ensure the pulling wire is free to move and does not bend during the test.
• Controlled loading rate; the stress increase in the pulling wire shall not exceed specified limits (example: 10 MPa/s) during the test.
• Measurement and recording of maximum force at joint failure and documentation of fracture location and mode.
• Requirements for repeatability and reporting of test conditions and results for quality control and comparative evaluation.

Typical use and users

Used by testing laboratories, manufacturers of welded fabric reinforcement, quality assurance personnel, construction material specifiers, and project engineers who need a standardised method to determine and compare welded-joint strength in reinforcement meshes. Also referenced by standards committees and certification bodies when establishing test regimes for welded fabric.

FAQ

Q: What is this standard?

A: ISO 10287:1992 is an ISO test-method standard titled "Steel for the reinforcement of concrete — Determination of strength of joints in welded fabric" that describes how to measure the tensile strength of welded joints in reinforcement mesh.

Q: What does it cover?

A: It covers specimen preparation, fixture/support arrangements, controlled loading (rate limits), measurement of maximum force at failure, and recording the fracture location and mode for welded fabric joints. It provides a procedure for performing the tensile test rather than setting pass/fail criteria.

Q: Who typically uses it?

A: Testing laboratories, welded-fabric manufacturers, QA/QC staff, specification writers, construction engineers, and standards committees use or referenced this method for material testing and comparative evaluation.

Q: Is it current or superseded?

A: ISO 10287:1992 is withdrawn. Its content has been superseded and incorporated into the ISO 15630 series of test methods for steel for the reinforcement and prestressing of concrete (ISO 15630 parts that cover welded fabric). Users should refer to the relevant, current part of ISO 15630 for up-to-date test procedures.

Q: Is it part of a series?

A: It was part of ISO work on reinforcement steels under ISO/TC 17/SC 16. Its test-method scope has been absorbed into the broader ISO 15630 series of test methods for reinforcement and prestressing steels.

Q: What are the key keywords?

A: Welded fabric, welded joint strength, tensile test, steel reinforcement, reinforcement mesh, ISO 10287, ISO 15630, test method.
