Change in Optical Transmittance

This test evaluates the change in optical transmittance of a fiber optic cable after exposure to one or more environmental or physical stress tests. It is not typically performed as a stand-alone test, but performed before, during, and after specified mechanical/environmental tests. A baseline measurement of optical power is recorded prior to any stress tests. […] Read more

Mating and Unmating Forces

The ability of a connector to mate and unmate regularly throughout its service life is essential to the maintainability of an electrical system. The mating/unmating forces tests this durability by performing repeated cycles of mating and unmating on the connector under test. Torque is measured at the start and end of the cycles to assess […] Read more

Pulse Response Time

The pulse response time test determines the ability of a completed cable for data transmission to propagate a square wave signal with the desired speed and accuracy. To assess the signal transmission, the evaluation involves the use of a signal generator, oscilloscope, and pulse transformer. Specimen failure is considered if the test cable exhibits a […] Read more

Cold Impact

Cold impact testing assesses whether a cable can withstand impact forces after being subjected to low temperatures without cracking and continue to maintain insulation properties. After exposure to a specified freezing temperature, a controlled mechanical impact is applied to the cable, simulating real-world scenarios such as accidental drops, crushing, or bending. The cable’s performance is […] Read more

Impact Resistance

Impact resistance testing evaluates a cable’s ability to withstand mechanical impacts, ensuring it can maintain its structural and electrical integrity in the presence of potential physical shocks. The test measures the impact force necessary to cause contact between the impact tool and the conductor specimen. The evaluation can be conducted with a blunt or a […] Read more

Insulation Percent Overlap

This evaluation ensures that the insulation layers are applied with the required amount of overlap to provide adequate protection and electrical insulation. The test uses a microscope with a magnification of 15 diameters minimum to measure the length of the spiral edge of the wrapped insulation in degrees of freedom. Read more

Magnetic Permeability

Magnetic permeability testing measures a connector’s ability to become magnetized when subjected to a magnetic field. This property is essential in applications where electromagnetic interference or compatibility is a concern. The test involves the use of a permeability meter to determine whether the magnetic permeability of the test material is below a specified value. Read more

Inclined Plane Tracking and Erosion

This test method evaluates an insulating solid’s resistance to surface tracking and erosion caused by contaminants in the presence of electrical stress. In the test, the conducting liquid contaminant is continuously supplied at a specified rate to the surface of the test specimen. This essentially produces continuous electrical surface discharge, which may cause specimen failure […] Read more

Dielectric Breakdown

Dielectric breakdown testing is performed to assess the ability of insulation material to tolerate high-voltage stress without electrical breakdown. The test measures the maximum voltage an insulator can withstand before puncture of the insulation occurs, making the insulation unable to inhibit current flow through the failure region. Parameters that can be adjusted: Method of voltage […] Read more

Terminal Strength

This test is performed to assess the strength of the connection between the wire and its termination to ensure the reliability and integrity of the electrical connection. The design of the terminals and method of their attachment must withstand the applicable mechanical stresses to which they will be subjected to during installation, disassembly, and regular […] Read more
