Abstract

Beiblatt 4 is an informative supplement to DIN EN ISO 7500-1 that gives guidance on how to consider measurement uncertainty when assigning a classification to material testing machines (tension/compression). It explains the role of uncertainty in the machine‑classification criteria and offers practical information to assist users and calibration laboratories in applying the classification rules of ISO 7500‑1.

Scope

This supplement provides users of DIN EN ISO 7500-1 with guidance on how to take measurement uncertainty into account when classifying the force‑measuring system of static uniaxial testing machines (tension and compression machines). It addresses the interpretation and inclusion of uncertainty contributions in the classification procedure specified in ISO 7500‑1 and is intended to assist calibration laboratories, test houses and machine manufacturers in applying the classification rules consistently. The scope is limited to the force‑measuring system and classification aspects referenced in Part 1 of ISO 7500.

Key topics and requirements

• Guidance on incorporating measurement uncertainty into the classification decision for material testing machines.
• Clarification of how uncertainty affects class limits and pass/fail decisions when evaluating relative deviation, repeatability and reversal (parameters such as q, b, v/u as used in ISO 7500‑1 analyses).
• Practical notes for calibration laboratories on evaluating and reporting uncertainty components relevant to force calibration and machine classification.
• Recommendations for documentation and interpretation when the uncertainty budget influences the assigned performance class.
• Informative examples and explanatory text (short supplement format — not a normative extension of the core verification tests).

Typical use and users

Used by accredited calibration laboratories, materials testing laboratories, manufacturers and maintainers of testing machines, quality managers and accreditation/inspection bodies that need to classify or verify static tension/compression testing machines according to DIN EN ISO 7500‑1. It is a practical aid when uncertainty evaluation is required to support a classification decision.

Related standards

Directly related to DIN EN ISO 7500‑1 (the main standard for calibration and verification of force‑measuring systems in uniaxial testing machines). Other related documents include ISO 7500‑2 (verification of tensile creep testing machines), ASTM E4 (force verification practices) and later consolidated editions of DIN EN ISO 7500‑1 (see subsequent revisions such as the 2015/2016 updates of ISO/DIN EN ISO 7500‑1). Users should consult the current edition of ISO 7500‑1 and applicable national implementation documents for the authoritative normative requirements.

FAQ

Q: What is this standard?

A: It is Supplement 4 (Beiblatt 4) to DIN EN ISO 7500‑1 (E DIN EN ISO 7500‑1/Bbl4:2012‑05), an informative document that helps users account for measurement uncertainty when classifying the force‑measuring systems of static uniaxial testing machines.

Q: What does it cover?

A: It covers guidance and explanatory information on how to include measurement uncertainty in the classification criteria of ISO 7500‑1 (effects on relative deviation, repeatability and reversal characteristics and on assigning a performance class). It does not change the normative test procedures of Part 1 but explains how uncertainty influences classification decisions.

Q: Who typically uses it?

A: Calibration and materials testing laboratories, machine manufacturers, metrology specialists and accreditation bodies use the supplement to support consistent, uncertainty‑aware classification of testing machines.

Q: Is it current or superseded?

A: The supplement was issued in 2012 (issue dated 23 April 2012 / publication entry May 2012). Some catalogue records list the document as withdrawn or cancelled; in practice users should check the current edition of DIN EN ISO 7500‑1 and national catalogues for the definitive status and any newer informative material. Later revisions of ISO 7500‑1 (published subsequently at the international and national level) consolidate requirements; consult the latest DIN/ISO edition for the binding verification rules.

Q: Is it part of a series?

A: Yes — it is Supplement 4 to Part 1 of the ISO/DIN series on verification of static uniaxial testing machines (ISO 7500 series). The broader series includes ISO 7500‑1 (force‑measuring system for tension/compression machines) and ISO 7500‑2 (verification of tensile creep testing machines), plus various national implementation notes and Beiblätter (supplements).

Q: What are the key keywords?

A: Measurement uncertainty, machine classification, force calibration, verification, ISO 7500‑1, tension/compression testing machines, Beiblatt 4.
