Fluid Immersion (Single Fluid)

EN 3909 defines the standard test fluids representing those commonly encountered in airborne and ground operations, including fuels, hydraulic fluids, lubricating oils, cleaning fluids, de-icing agents, fire extinguishants, and avionic cooling fluids. Each fluid has specified test temperatures and a three-stage test protocol.The standard requires components to be tested according to the appropriate component-specific test […] Read more

Cable Repeated Bend Radius

EN3745-512 specifies the method for testing the crush resistance of aerospace fiber optic cables. A cable specimen is placed between flat plates or rollers and subjected to controlled compressive loads while monitoring optical performance.The test measures the change in optical attenuation as increasing lateral force is applied to the cable. Both transient effects during loading […] Read more

Bending Test – Method B

EN3745-510 specifies the method for testing aerospace fiber optic cables under sinusoidal vibration conditions. Cable specimens are mounted on a vibration fixture and subjected to controlled vibration profiles across specified frequency ranges and acceleration levels.During vibration, optical transmission properties are monitored to detect any changes in attenuation or signal interruption. After testing, specimens are evaluated […] Read more

Bending Test – Method A

Resistance to Contamination and Aircraft Fluids (no posttest scrape)

EN3745-411 specifies two test methods for determining the resistance of aerospace fiber optic cables to fluid exposure. Method 1 (occasional contamination) tests cables against accidental fluid contact, while Method 2 (extended contamination) tests cables intended for areas with prolonged fluid exposure.Specimens are immersed in test fluids specified in EN 3909 at controlled temperatures for defined […] Read more
