Overview
EN 2591-203:1996 (CEN) is an aerospace test-method standard that specifies how to measure electrical continuity at the microvolt level for a pair of mated contacts and their terminations. The method is intended for situations where the current flowing across the contacts is very low compared with the connector’s nominal current rating. This test supports verification of contact integrity for low-level signals in aerospace electrical and optical connection elements.
Key topics and requirements
- Scope: Measurement of electrical continuity between mated contact pairs and their terminations at microvolt sensitivity.
- Test focus: Detecting very small voltage drops and continuity issues that may not appear under nominal-current tests.
- Precision measurement: Requires instrumentation and procedures capable of resolving microvolt-level voltage differences across contacts.
- Applicability: Intended for connector elements used in aerospace systems where low-level signal integrity is critical (e.g., sensor lines, instrumentation).
- Test conditions: Emphasizes performing continuity measurement under controlled conditions with mated contacts and terminations; currents used are intentionally much lower than rated currents to reveal microvolt-level discontinuities.
- Repeatability and documentation: Tests should be repeatable and results recorded to support quality assurance and compliance activities.
(Note: This summary reflects the standard’s stated scope and purpose. Specific test setup, instruments, pass/fail criteria and procedural steps are defined within the full EN 2591-203:1996 document.)
Applications
- Avionics and aerospace manufacturing: Verify low-level signal paths in harnesses, connectors and sensor interfaces where microvolt-level drops can affect system performance.
- Connector qualification and acceptance testing: Provide sensitive continuity checks during connector development, production inspection and procurement acceptance.
- Maintenance and troubleshooting: Detect marginal contacts or degradation that won’t be revealed by standard current-rated continuity tests.
- Quality assurance and regulatory compliance: Supply documented, repeatable test data for certification, non-conformance analysis and lifecycle monitoring.
