Abstract

This supplement (Beiblatt 4) provides informative guidance to users of DIN EN ISO 7500-1 on how to take measurement uncertainty into account when assigning a class to a material testing machine (tension/compression). It is intended as explanatory/supporting material to the main verification and calibration requirements for the force‑measuring system.

Scope

This Beiblatt is an informative supplement to DIN EN ISO 7500-1 (the main part addressing verification and calibration of the force‑measuring system of static uniaxial testing machines). It specifically explains approaches and considerations for including measurement uncertainty when classifying testing machines into performance classes; it does not change the normative calibration/verification procedures but helps users interpret classification limits in light of uncertainty.

Key topics and requirements

• Principles for accounting for measurement uncertainty when comparing measured/calibrated force values with class limits.
• Guidance on how measurement uncertainty affects machine classification (choice/assignment of class based on calibrated performance and uncertainty margins).
• Explanatory examples and recommendations to assist calibration laboratories and users in consistent application of classification rules.
• Relationship of the guidance to the normative verification and calibration procedures in DIN EN ISO 7500-1 (the Beiblatt is informative/supporting, not a normative amendment of the main text).

Typical use and users

Calibration and testing laboratories, manufacturers and maintainers of material testing machines, quality and metrology managers in industrial testing facilities, and standards/technical committees use this supplement to ensure consistent interpretation of machine classes when measurement uncertainty is significant. It is also used by accreditation bodies and conformity assessment entities when assessing laboratory procedures for machine verification.

FAQ

Q: What is this standard?

A: It is an informative supplement (Beiblatt 4) to DIN EN ISO 7500-1 that provides guidance on taking measurement uncertainty into account when classifying static uniaxial material testing machines (tension/compression).

Q: What does it cover?

A: It covers explanatory guidance and examples showing how to consider measurement uncertainty in the process of assigning a machine class, and how uncertainty interacts with the verification/calibration results from the force‑measuring system; it does not replace or change the normative calibration steps in the main part.

Q: Who typically uses it?

A: Calibration laboratories, test-machine manufacturers, metrology/quality personnel in testing labs, accreditation bodies and others involved in machine verification and classification. The supplement helps ensure consistent, uncertainty‑aware classification decisions.

Q: Is it current or superseded?

A: Beiblatt 4 was issued in March 2013 and is published as DIN EN ISO 7500-1 Beiblatt 4:2013-03. Catalogues list it as an active supplement; users should check the DIN/ISO catalogue or national standards body for any later amendments, withdrawals or newer related documents that may affect application.

Q: Is it part of a series?

A: Yes — it is one of the Beiblätter (supplements) associated with DIN EN ISO 7500-1 (Beiblatt 1–4 historically provide additional information and guidance alongside the main part). The main numbering and series relationship is DIN EN ISO 7500-1 with individual Beiblätter providing supplementary information.

Q: What are the key keywords?

A: Measurement uncertainty; classification; calibration; verification; force‑measuring system; material testing machine; tension/compression; DIN EN ISO 7500-1; Beiblatt 4.
