Full title and description

ISO/TR 15263:2024 — Measurement uncertainties in mechanical tests on metallic materials — The evaluation of uncertainties in tensile testing. This technical report provides guidance on how to obtain and evaluate measurement uncertainty in tensile tests performed at room temperature and at elevated temperature, with emphasis on axial loading conditions and digital acquisition of force and displacement.

Abstract

The report describes procedures for the evaluation of uncertainties in tensile testing of metallic materials, covering tests at room temperature (with reference to ISO 6892‑1) and at elevated temperature (with reference to ISO 6892‑2). It addresses tests run continuously on specimens with uniform gauge length, describes recommended measurement and data‑acquisition practices, and includes an informative annex that shows typical scatter observed in inter‑laboratory exercises.

Scope

ISO/TR 15263:2024 gives guidance on evaluating measurement uncertainty for tensile tests on metallic materials performed under axial loading. The guidance applies to tests at room temperature (in accordance with ISO 6892‑1) and at elevated temperature (in accordance with ISO 6892‑2), and assumes continuous test runs on specimens with uniform gauge length. The report describes how to use digitally acquired force and displacement data in the uncertainty evaluation and provides typical scatter information for various materials as an informative annex.

Key topics and requirements

• Framework for identifying and quantifying uncertainty components in tensile tests (instrumentation, specimen geometry, environmental and procedural factors).
• Application to tensile testing at room temperature and elevated temperature, referencing ISO 6892‑1 and ISO 6892‑2 test methods.
• Recommendations for data acquisition: digital recording of force and displacement, use of appropriate extensometers or displacement measurement methods, and verification of machine accuracy.
• Statistical treatment of repeatability and reproducibility, propagation of uncertainty through calculated mechanical properties (e.g., yield strength, ultimate tensile strength, elongation).
• Assumptions and limitations: continuous tests, uniform gauge lengths, and conditions under which the report’s example scatter data are representative.
• Informative Annex C: examples/indications of typical scatter from inter‑laboratory exercises to aid realistic uncertainty estimation.

Typical use and users

Primary users are materials testing laboratories, quality and conformity assessment bodies, calibration laboratories, research institutions, and manufacturers performing tensile testing on metallic materials who need to estimate and report measurement uncertainty for tensile properties. Standardization committees and accreditation assessors will also use the report as guidance when assessing test methods and uncertainty declarations.

Related standards

This technical report is intended to be used alongside the tensile testing standards ISO 6892‑1 (Method of test at room temperature) and ISO 6892‑2 (Method of test at elevated temperature). It was developed under ISO/TC 164/SC 1 (Mechanical testing of metals) and cross‑references other relevant guidance (including CWA 15261‑2 and UNCERT CoP reports noted in the ISO abstract).

FAQ

Q: What is this standard?

A: ISO/TR 15263:2024 is a Technical Report that provides guidance on evaluating measurement uncertainty specifically for tensile tests on metallic materials. It is an informational document (TR) intended to support accurate uncertainty estimation for tensile properties.

Q: What does it cover?

A: It covers methods for deriving and combining uncertainty components for tensile tests performed at room temperature and elevated temperature, practical recommendations for instrumentation and digital data acquisition, statistical treatment of scatter, and illustrative typical scatter values in an informative annex. The report references ISO 6892‑1 and ISO 6892‑2 for the underlying test methods.

Q: Who typically uses it?

A: Materials testing laboratories, calibration and accreditation bodies, manufacturers and R&D organizations performing tensile testing, and standards or compliance personnel who need to declare or assess measurement uncertainty for tensile properties.

Q: Is it current or superseded?

A: ISO/TR 15263:2024 is published and current as of its publication (January 31, 2024). As a Technical Report it provides guidance rather than normative requirements; users should check the ISO catalogue or their national standards body for any later revisions or related normative documents.

Q: Is it part of a series?

A: The report is related to the ISO 6892 series (tensile testing of metallic materials — Parts 1 and 2 cover room and elevated temperature methods). It was developed under ISO/TC 164/SC 1 and is intended to be used in conjunction with those normative test standards.

Q: What are the key keywords?

A: Measurement uncertainty, tensile testing, metallic materials, ISO/TR 15263, ISO 6892‑1, ISO 6892‑2, force acquisition, displacement measurement, inter‑laboratory scatter.
