Full title and description

ISO 10606:1995 — Steel for the reinforcement of concrete — Determination of percentage total elongation at maximum force. This International Standard specifies two methods for determining the percentage total elongation at maximum force by tensile testing of ordinary reinforcing steel: (1) measurement using an extensometer during the tensile test, and (2) measurement after fracture (manual method).

Abstract

Specifies two test methods to determine the percentage total elongation at maximum force (Agt) for reinforcing bars, wire rod and wire used as concrete reinforcement. One method records elongation with an extensometer before load drop; the other measures elongation on the fractured specimen and applies the defined correction/calculation. The standard was concise (4 pages) and focused on procedural definitions and measurement conditions.

• Edition / version: Edition 1, 1995.
• Number of pages: 4.

Scope

Defines the procedure(s) to determine percentage total elongation at maximum force (Agt) for ordinary reinforcing steel by tensile testing, including required gauge lengths, the timing of extensometer readings (if used), and how to measure after fracture and apply the appropriate calculations. The scope is limited to test method specification rather than product performance limits.

Key topics and requirements

• Two accepted measurement methods: extensometer-based recording during test and manual measurement after fracture with specified gauge length and correction formula.
• Requirements for test-piece preparation, gauge length (commonly 100 mm for Agt measurement), and marking positions for the manual method.
• Specifications for test equipment accuracy and calibration (testing machine and extensometer classes referenced).
• Instructions for when a test is invalid (e.g., fracture in grips or insufficient distance from grips to measurement gauge).
• Reference to related tensile-test standards (e.g., ISO 6892) and later consolidated test-method standards that supersede ISO 10606.

Typical use and users

Used by test laboratories, material certification bodies, rebar manufacturers, quality-control engineers, and construction materials researchers concerned with mechanical-property verification of steel reinforcement. After withdrawal, users typically follow the consolidated test-method standards (ISO 15630 series) that replaced ISO 10606.

Related standards

ISO 10606:1995 has been superseded and its test methods incorporated into the ISO 15630 series (notably ISO 15630-1:2002 and subsequent revisions), which provide consolidated test methods for reinforcing and prestressing steels. It also references general tensile-test standards such as ISO 6892.

FAQ

Q: What is this standard?

A: ISO 10606:1995 is an ISO test-method standard titled "Steel for the reinforcement of concrete — Determination of percentage total elongation at maximum force" that defined procedures for measuring percentage total elongation (Agt) of reinforcing steel.

Q: What does it cover?

A: It covers two measurement methods for Agt (extensometer during test and manual measurement after fracture), requirements for specimen marking and gauge length, equipment class/calibration, and validity criteria for tensile tests on reinforcing steel.

Q: Who typically uses it?

A: Test laboratories, rebar manufacturers, materials/quality engineers, and technical committees involved in steel reinforcement testing and certification. After withdrawal, users generally follow the replacement ISO 15630 series.

Q: Is it current or superseded?

A: ISO 10606:1995 has been withdrawn (withdrawal recorded in 2002) and its content was consolidated into the ISO 15630 series (e.g., ISO 15630-1:2002 and later revisions). It is therefore superseded and not the active test-method reference.

Q: Is it part of a series?

A: Not originally a multi-part series itself, but its methods were absorbed into the multi-part ISO 15630 series (test methods for steel for reinforcement and prestressing of concrete).

Q: What are the key keywords?

A: Reinforcing steel, elongation at maximum force, tensile testing, extensometer, Agt, rebar test methods, withdrawn standard, ISO 15630.
