Overview

EN ISO 7500-1:2018 - "Metallic materials - Calibration and verification of static uniaxial testing machines - Part 1: Tension/compression testing machines - Calibration and verification of the force‑measuring system" is the CEN-adopted version of ISO 7500-1:2018. The standard specifies procedures for the calibration and verification of the force‑measuring system used in static tension and compression testing machines. It covers a general inspection, force‑measuring system calibration and the confirmation that a testing machine meets the performance limits for a specified class.

Note: EN ISO 7500-1:2018 addresses static calibration only - calibration results are not guaranteed for high‑speed or dynamic testing.

Key topics and requirements

General inspection of the testing machine and force-application accessories (see Annex A).
Calibration of the force‑measuring system using force‑proving instruments; establishes relationship between machine-indicated force and reference force (see ISO 376 as normative reference).
Determination of resolution and variation of readings for analogue and digital force indicators.
Alignment, temperature compensation and conditioning of the testing machine and force‑proving instrument before measurement.
Calibration procedure: application of discrete forces, verification of accessories, piston-position effects, and reversibility/error estimation.
Performance assessment metrics: relative indication error, relative repeatability error, agreement between instruments, and uncertainty estimation (informative Annex C).
Classification and acceptance: confirmation that the machine achieves limits for a specified class and generation of a verification report with results and intervals between verifications.
Safety caution: some tests can create hazardous situations; appropriate safeguards are required.

Practical applications and users

Who uses EN ISO 7500-1:2018:

Calibration and metrology laboratories performing force calibrations.
Mechanical testing laboratories conducting tensile and compression tests on metals.
Manufacturers and maintainers of uniaxial testing machines who need type verification or factory calibration.
Quality managers, materials engineers and conformity assessment bodies requiring traceable force measurement for material certification, R&D, and production quality control.

Practical benefits:

Ensures traceable, repeatable force measurements for static material tests.
Provides a standardized basis for comparing testing machines and meeting accreditation requirements.
Helps manage measurement uncertainty, repeatability and machine classification.
