Overview
EN 60255-21-1:1995 (CLC) specifies sinusoidal vibration tests for measuring relays and protection equipment. It is Part 21, Section 1 of the EN 60255 series covering vibration, shock, bump and seismic tests. The standard defines two type-test methods - the vibration response test and the vibration endurance test - and is generally based on the environmental test procedure EN 60068-2-6. Requirements apply only to equipment in a new condition and are intended for type testing to verify mechanical and functional performance under sinusoidal vibration.
Key Topics and Requirements
- Scope: Applies specifically to measuring relays and protection equipment; testing is for type approval rather than production inspection.
- Test types:
- Vibration response test - assesses relay functional performance under specified sinusoidal vibration inputs.
- Vibration endurance test - evaluates long-term mechanical and electrical durability under sustained vibration.
- Test basis: Test methods and principles are generally aligned with EN 60068-2-6 (sinusoidal vibration).
- Condition of equipment: Tests are defined for devices in a new (as-manufactured) condition.
- Sinusoidal vibration: The standard focuses on sinusoidal excitation (single-frequency sweep or dwell), rather than random vibration or shocks.
Applications
EN 60255-21-1 is used by professionals who need to demonstrate that relays and protection devices maintain accuracy, reliability and mechanical integrity when exposed to vibration in service environments:
- Relay and protection equipment manufacturers - for type testing new product designs and generating compliance data.
- Test laboratories - to perform standardized vibration response and endurance tests for certification reports.
- Utility and substation engineers - to specify ruggedness requirements for protective relays used in power systems.
- Component and enclosure designers - to validate mounting, damping and mechanical robustness against sinusoidal vibration.
- Quality and compliance teams - to ensure products meet applicable type-test standards before market release.
