ISO 10606:1995 is a tensile-testing standard for reinforcing steel used in concrete construction. It focuses on determining the percentage total elongation at maximum force, a ductility-related value commonly referenced for rebar and similar reinforcing products.
This document is withdrawn, and many projects instead cite later ISO 15630 series parts for reinforcement test methods. If you need help matching a project specification to the right current edition or replacement document, talk with our team.
ISO 10606:1995 — Steel for the reinforcement of concrete — Determination of percentage total elongation at maximum force
ISO 10606:1995 describes how to determine the percentage total elongation at maximum force for ordinary reinforcing steel using a tensile test. The standard includes two approaches: one based on extensometer measurement during the test, and another based on measurement after fracture.

Quick Definition
ISO 10606:1995 defines ways to measure how much reinforcing steel elongates (in %) up to the point where the tensile test reaches its maximum force.
Common outputs: A reported percent elongation value at maximum force, tied to the tensile test record and the measurement approach used.
What This Standard Covers
This standard focuses on determining percentage total elongation at maximum force for ordinary reinforcing steel by tensile testing.
Two measurement approaches are included:
- Measurement using an extensometer during the tensile test.
- Measurement based on the test piece after fracture (post-test measurement).
ISO 10606 is not a full product specification for reinforcement; it is a targeted method for one ductility-related characteristic derived from tensile testing.
Why This Standard Matters in Testing
For reinforcing steel, percent elongation behavior is commonly used as an indicator of ductility and deformation capacity. Reporting elongation at maximum force can be important when a purchaser or project specification needs a consistent way to compare reinforcement products or verify compliance with a stated ductility requirement.
Because the result depends on how strain/extension is measured and when it is referenced (at maximum force), the test setup and instrumentation choice can affect how confidently results can be compared across labs and suppliers.
Common Materials, Product Types, or Applications Covered
ISO 10606:1995 applies to steel for the reinforcement of concrete, typically in the form of conventional reinforcing products used in construction.
Common product examples: Reinforcing bars (rebar) and other ordinary reinforcing steel products where tensile-test ductility metrics are required by a contract, procurement document, or quality plan.
Common Test or Verification Workflow
ISO 10606 is used within a tensile testing workflow where a reinforcement test piece is loaded in tension until failure while force is recorded and extension is measured either during the test or assessed afterward.
Typical workflow elements: Selecting and preparing a representative test piece, running a controlled tensile test to capture the maximum force, and determining the percent total elongation at that maximum-force point using the chosen measurement approach.
Equipment Commonly Used for This Standard
Because ISO 10606 is tensile-test-based, equipment selection centers on safely loading reinforcement specimens and accurately measuring extension/elongation associated with the maximum-force point.
Common equipment families: Universal testing machines (UTMs), appropriate reinforcement grips/fixtures, extensometers (when using in-test measurement), and test software for force/extension capture and reporting.
Practical quoting caution: Rebar size range, surface profile, and expected maximum forces drive grip style and machine capacity. If you are planning a reinforcement tensile setup and need capacity and fixture guidance, you can request pricing for a tensile test system configured around your specimen range and reporting needs.
How to Read This Designation or Revision
ISO 10606:1995 identifies the ISO standard number (10606) and the publication year (1995). This document is listed as withdrawn, which means many specifications will instead cite a replacement method.
When a drawing, contract, or QA plan references ISO 10606, confirm whether it requires the withdrawn 1995 document explicitly or whether it allows an updated ISO 15630 series method for reinforcement testing.
Related Standards, Methods, or Frameworks
ISO identifies the ISO 15630 series (Parts 1, 2, and 3; 2002 editions) as newer versions associated with ISO 10606. For many reinforcement programs, those later parts are where tensile testing and related reinforcement test methods are referenced.
If your requirement mixes ISO 10606 with other tensile testing references, it is important to align the edition requirements and reporting expectations across the full document stack.
