General Information
Overview
EN 60255-21-2:1995 (CLC) is a European standard, part of the EN 60255 series, that specifies shock and bump tests for measuring relays and protection equipment. It forms Section 2 of Part 21, which collectively addresses vibration, shock, bump and seismic tests. The standard covers two types of tests: the shock test (applicable to both energized and non‑energized specimens) and the bump test (applicable to non‑energized specimens). Requirements apply only to relays and protection devices in a new condition.
Key Topics
- Scope and applicability
- Applies specifically to measuring relays and protection equipment.
- Tests are intended for devices in a new (unaged) state.
- Test types
- Shock test: performed on both energized and non‑energized specimens to evaluate resistance to sudden high‑acceleration impacts.
- Bump test: performed on non‑energized specimens to assess response to repeated small impacts.
- Performance criteria
- Ensures that mechanical integrity and functional performance are maintained after shocks and bumps.
- Defines test procedures, specimen conditioning, and acceptance checks (functional/visual inspection and electrical operation).
- Test setup and instrumentation
- Outlines mounting, orientation and monitoring requirements to ensure repeatable test conditions and valid results.
- Documentation
- Emphasizes recording test conditions and outcomes for compliance and traceability.
Applications
EN 60255-21-2 is used where reliable relay operation under shock and bump conditions is critical. Typical users and applications include:
- Protection relay manufacturers - for design validation and type testing to demonstrate mechanical robustness.
- Independent testing laboratories - to perform standardized shock and bump certification.
- Power utilities and substation engineers - to specify procurement requirements that ensure equipment reliability under transport, handling or fault conditions.
- Quality assurance and compliance teams - to verify that new relays meet European test expectations before installation.
Related Standards
- EN 60255 series (electrical relays) - Part 21 covers vibration, shock, bump and seismic tests as a group.
- National adoptions of EN 60255-21-2 (identified by local standards bodies) may exist; users should check the latest regional versions or amendments.
