Full title and description

STB DIN EN ISO 7500-1 Beiblatt 3 E 2012-09 — Metallic materials — Verification of static uniaxial testing machines — Part 1: Tension/compression testing machines — Verification and calibration of the force‑measuring system — Supplement 3: General information for requirements, verification and calibration of fatigue (dynamic) testing machines. This Beiblatt (supplement) provides guidance specific to fatigue (oscillatory) testing machines as an informative supplement to DIN EN ISO 7500-1.

Abstract

This supplement gives general information on requirements, verification and calibration procedures for fatigue (dynamic/oscillatory) testing machines used to apply cyclic tension, compression or torsion to metallic test specimens. It complements the static-force verification rules of Part 1 by addressing machine features, measurement considerations and additional checks relevant to fatigue test systems.

Scope

This Beiblatt supplies general guidance on special requirements and verification/calibration activities for fatigue (dynamic or oscillatory) testing machines that are not fully covered by the static-force verification procedures of DIN EN ISO 7500-1 Part 1. Topics include machine-specific considerations for cyclic loading, force application and transmission under dynamic conditions, additional measurement checks, and recommendations for calibration practice where dynamic effects influence force measurement. The supplement is informative and intended to be read together with the main Part 1 text.

Key topics and requirements

• Definitions and terminology specific to fatigue/oscillatory testing machines.
• General requirements for machine construction and safe operation under cyclic loading.
• Recommendations for verification of force-measuring systems when subject to dynamic or cyclic operation (including considerations of inertia, resonances and load transmission).
• Suggested calibration and check points beyond static load steps, and guidance on when static calibration values may not apply to dynamic testing.
• Guidance on record keeping, uncertainty considerations and when additional specialist measurement equipment is needed for dynamic verification.

Typical use and users

Used by calibration laboratories, testing-machine manufacturers, quality/assurance engineers, and R&D groups that operate or verify fatigue (dynamic) testing machines for metallic materials. Typical applications include development and verification of servo-hydraulic or electrodynamic fatigue testing systems, periodic verification of force-measuring components under cyclic conditions, and preparation of laboratory test methods that require traceable force measurement for fatigue testing.

FAQ

Q: What is this standard?

A: It is a Beiblatt (informative supplement) to DIN EN ISO 7500-1 issued in September 2012 that gives general information and guidance on requirements, verification and calibration of fatigue (oscillatory/dynamic) testing machines used for metallic materials.

Q: What does it cover?

A: It covers machine-specific considerations for cyclic loading, recommendations for verification and calibration of force-measuring systems where dynamic effects are relevant, and guidance on additional checks, uncertainties and record keeping needed for fatigue testing machines. It is intended to supplement the static verification rules in Part 1.

Q: Who typically uses it?

A: Calibration laboratories, testing-machine manufacturers, test laboratory managers, quality engineers and technical staff responsible for commissioning, maintaining or verifying fatigue/oscillatory testing machines.

Q: Is it current or superseded?

A: The Beiblatt 3:2012-09 entry is catalogued in some references as withdrawn/cancelled and its technical content has been incorporated or superseded by later revisions and consolidated editions of ISO/DIN EN ISO 7500-1 (see ISO 7500-1:2018 and later national versions). Users should consult the current edition of ISO/DIN EN ISO 7500-1 and national status information to determine applicable requirements today.

Q: Is it part of a series?

A: Yes — it is a supplement to DIN EN ISO 7500-1 (Part 1 of the ISO 7500 series) and sits alongside other Beiblätter (supplements) and related parts that address different machine types or specific checks; the overall ISO 7500 series and related ISO/TC 164 documents cover verification of testing machines.

Q: What are the key keywords?

A: fatigue testing, oscillatory testing, force calibration, verification, force-measuring system, tensile/compression testing machines, DIN EN ISO 7500-1, Beiblatt 3.
