Low Fluoride Off Gassing

During the degradation process of ETFE and XL-ETFE, fluorine gas is released from the insulation into the environment. While the outgassing is not a problem in open or well-ventilated areas, when stored or used in enclosed areas, the fluorine outgas may react with moisture to form a highly corrosive acid (hydrofluoric acid). Numerous system components […] Read more

Insulation Crosslink Proof

This test is to be used to evaluate the cross-linking of certain types of wire insulation. In this test, the sample is exposed to a temperature above the wire rating for a short duration. If the sample insulation has not been properly cross-linked, then the elevated temperature and mechanical stressing of this test will cause […] Read more

Resistance to Fluids

Regardless of the particular application on an aircraft, at some point in a wire/cable’s service life, it will become exposed to fluids. These may be fuel, hydraulic fluid, cleaners, deicers, and/or a variety of other fluids. It is critical that the wire/cable insulation is not adversely affected with exposure to these fluids. In particular, the […] Read more

Wet Arc Propagation Resistance

The wet arc-resistance test for wire insulation provides an assessment of the ability of an insulation to prevent damage in an electrical arc environment. In service, electrical arcs may originate from a variety of factors including insulation deterioration, faulty installation, and chafing. It has been documented that results of an arc-propagation test may vary slightly […] Read more

Adherence of Plating

Some wire insulation types have a well-defined accelerated aging processes, whereas others have a rather non-active one in terms of standard aging (heat, strain, and humidity). This procedure provides a vetted process for assessing the age degradation process for polyalkene wire. The life cycling of polyalkene wire is a three-step process that starts with placing […] Read more
