Overview
EN 6059-504:2014 is a CEN European Standard in the Aerospace series that specifies test methods to assess temperature rise within a cable loom (self-heating) when protected by a sleeve or conduit. Intended for aerospace electrical installations, the standard describes laboratory procedures to measure how protective sleeves affect cable temperatures under normal and fault currents. EN 6059-504:2014 is to be used together with EN 6059-100 (general test requirements).
Key topics and requirements
- Scope: Methods to evaluate behaviour and temperature increase of a cable loom fitted with protection sleeves or conduits subject to electrical heating.
- Test setup:
- Use a 3 m cable loom of airframe cables with insulation temperature rating at least equal to the sleeve material.
- Conductors are wired in series so the same current flows through each conductor; provide voltage pick-off over a test zone (minimum 1.5 m).
- Tests performed in a draft-free ambient chamber (typically 20 °C); use a screen to identify smoke.
- Method 1 - Heat transfer ratio:
- Measure loom temperature rise without sleeve (raise conductor temperature ~40 °C above ambient, stabilize for 30 min).
- Fit the protective sleeve and reapply current; after 30 min calculate the heat transfer ratio (percentage increase caused by the sleeve).
- Acceptance: heat transfer ratio shall not exceed the value specified in the product standard.
- Method 2 - Internal overheating assessment:
- Fit sleeve before heating. Raise loom temperature to the sleeve’s maximum rated temperature, then to 30 °C above that rating and hold for 15 min.
- Acceptance: no visible smoke, smell, appreciable colour change, spontaneous combustion, or separation/embrittlement after cooling.
- Measurements: Temperature is derived from conductor resistance change using the standard formula and the appropriate temperature coefficient (α) given in the standard.
Practical applications and users
- Aerospace manufacturers and wiring-harness designers evaluating protective sleeves and conduits.
- Test laboratories and qualification teams performing environmental and electrical certification of cable assemblies.
- Maintenance, safety and reliability engineers assessing retrofit protection or ensuring compliance with aerospace electrical installation requirements.
- Suppliers specifying sleeve materials to meet thermal performance and fault-current resilience.

- Product-specific standards that define allowable heat transfer ratio limits and material temperature ratings.
