Overview
EN 3475-414:2005 is a CEN (Aerospace series) test-method standard that defines a differential scanning calorimeter (DSC) procedure to measure the level of sintering of PTFE tape on finished aircraft cables. The standard is intended for use together with EN 3475-100 (general test rules for aerospace cables) and ASTM D4591-01 (DSC method for fluoropolymers). It specifies the required temperature ranges, melting/recrystallization criteria and reporting expectations for qualifying PTFE-sheathed cables.
Key topics and requirements
- Scope: Measurement of PTFE tape sintering on finished cables using DSC.
- Normative references: EN 3475-100 and ASTM D4591-01 (DSC method for fluoropolymers).
- Test temperature ranges:
- Testing: 270 °C to 380 °C
- Calculation of melting point energy: 290 °C to 360 °C
- Acceptance criteria for PTFE sintering:
- Melting point temperature: (327 ± 4) °C
- Melting enthalpy (energy): 15 J/g to 25 J/g
- Recrystallization temperature: ≥ 310 °C
- Second melting point enthalpy: ≤ 25 J/g
- Reporting:
- Manufacturer must record which DSC apparatus was used.
- Qualification test values form the manufacturing process reference; production tests must use the same DSC apparatus and compare results to these reference values.
Applications and users
Who uses EN 3475-414:2005:
- Aerospace cable manufacturers performing quality control on PTFE-wrapped conductors
- Materials and test laboratories conducting DSC analysis for cable qualification
- Quality engineers and production control teams establishing process acceptance criteria for PTFE sintering
- OEMs and certification bodies evaluating thermal and physical integrity of cable insulation
Practical value:
- Ensures consistent PTFE sintering - critical for dielectric performance, mechanical stability and long-term reliability of aircraft electrical cables.
- Provides traceable DSC-based acceptance limits to align production testing with qualification benchmarks.
