General Information

Overview
EN 60524:1993 (published by CLC) is the European standard for direct-current resistive volt ratio boxes. It applies to d.c. resistive volt ratio boxes with fixed ratios and a ratio input voltage up to 1.5 kV, and covers any equipment built in or supplied as an essential part of the volt ratio box. The standard defines a classification system, accuracy classes (including a class index of 0.1 or better), permissible errors, marking requirements, and the information manufacturers must supply.
Key topics and requirements
- Scope: Applies to fixed‑ratio DC resistive volt ratio boxes and essential built‑in or supplied components up to 1.5 kV ratio input.
- Classification system: Defines accuracy classes for volt ratio boxes (for example classes with a class index of 0.1 or better are covered).
- Permissible errors: Specifies allowable deviations for each accuracy class and the limits that determine compliance.
- Conditions for error determination: Sets the environmental and measurement conditions under which errors and accuracy must be evaluated.
- Marking requirements: Requires clear markings on the instrument to identify ratio, accuracy class and other essential data.
- Manufacturer information: Defines the information to be supplied with the product (e.g., performance data, calibration details, intended use and limitations).
- Applicability to supplied equipment: Includes requirements for components supplied or integrated by the manufacturer as essential parts of the volt ratio box.
Applications
EN 60524:1993 is relevant wherever precise DC voltage division and traceable ratio measurements are required:
- Calibration and metrology laboratories performing voltage ratio comparisons
- Manufacturers of test and measurement equipment that include DC volt ratio boxes or resistive voltage dividers
- Electrical utilities and power engineering labs using ratio boxes for instrument calibration and verification
- Research institutions and universities conducting electrical measurement and instrumentation work
- Inspection and conformity assessment bodies verifying compliance of voltage division devices
Who should use this standard
- Test‑equipment designers and manufacturers (to design and label compliant devices)
- Calibration laboratories and metrologists (to evaluate and verify volt ratio accuracy)
- Procurement and quality teams (to specify required accuracy class and documentation)
- Compliance officers and certification bodies (to assess conformity with European practice)
Related standards
- IEC 60524:1975 (+ A1:1981) - the international reference cited in the standard
- ICS classification: 17.220.20 (Measurement of electrical and magnetic quantities)
