Flex Life at Crimp Termination

This test evaluates the ability of a terminated wire sample to maintain its structural integrity under conditions of repeated stress at the point of termination. The location of a crimp termination on a wire is more likely to experience conditions of mechanical stress than other locations along the length of the wire. It is crucial […] Read more

Phase Constant

A phase constant is a physical property of a propagating sine wave representing the shift in phase the wave experiences while travelling along its path. This test measures the phase constant of a twisted pair cable as a value of radians per length. Lectromec uses a spectrum analyzer to make all relevant measurements in determining […] Read more

Phase Delay

Phase delay is a measure of the delay in time a signal is emitted and when it is received at the other end. It is important that signal carrying cable adhere to a minimum phase delay to ensure timely and accurate function of the relevant system(s). The phase delay (propagation delay) is calculated from the […] Read more

Shield Coverage

Shield coverage is determined by a mathematical formula as defined in AS85485 dependent on the physical properties of the cable shield. Read more

VSWR/ Return Loss

Return Loss is a relative measurement of the reflected signal on a cable. In an ideal system, no signal would be reflected, all of the power on a signal would be received by the load, and the return loss would be infinite. In real-life applications, there will always be at least some amount of the […] Read more

Cable Weight

Knowing the weight of every component on an aircraft, down to the last wire, is vital to good design. This test is to be used to evaluate the weight of a finished cable specimen. Testing follows the same measurement procedure of the AS4373 procedure 1 method of the wire weight test: Measurements of cable weight […] Read more

Wire Weight

Knowing the weight of every component on an aircraft, down to the last wire, is vital to good design. This test is to be used to evaluate the weight of a finished wire specimen, it may also be applied to uninsulated conductor for certain standards. Measurements of wire weight may be made of loose wire […] Read more

Strip Force Test

The strip force test quantitatively evaluates the ease of removing insulation from a finished wire sample. It is important in any electrical system that wire insulation be adherent enough to the conductor to maintain structural integrity and non-adherent enough such that a standard wire stripping tool may readily remove insulation as needed. The insulation of […] Read more

Heat Resistance

The heat resistance test evaluates the ability of an insulative sample to maintain tensile strength after undergoing an elevated temperature exposure. The heat resistance test consists of a heat exposure followed by a tensile elongation test. Specimens are suspended in an oven for a selected temperature and duration, after which time they are removed and […] Read more

Heat Shock

The heat shock test evaluates the ability of an insulative material to endure elevated temperature conditions. Slight variations in test setup exist between the test standards covered by this listing and should be considered before choosing which standard best suits your needs. Each standard covered in this listing involves the same three elements: An elevated […] Read more
