In the application material that refers somewhere, UL can help you obtain the attestation letter that applies to many markets.

Material of practical electrical wiring (AWM) AWM is to be used in commonly / use at electric equipment or system. Material of every kinds of electrical wiring has thousands of planting model, because of electrical wiring make, of rating and utility different and different. The applicable standard of this kind of material is UL 758.

Material of every kinds of electrical wiring has one page technically " model page " , in order to describes his to form and provide model. The information in model page has temperature, rated pressure, conductor dimension and material, insulation layer material and ply, armored material and ply (if have) , to the description of screen or oversheath, UL evaluates the reference standard of this product, to the proposal that the spot represents, the antagonism program of UL checks, wants sign and the narration to its suitable scope.

Assessment type The wiring data that evaluates a component and cable include those who examine data to be able to be lighted degree, what heat source and power source ignite is characteristic, physics and physical characteristic and analytic sex check. Still have additionally expose for long at high temperature (gas stove ageing) , water, ultraviolet ray, the character below the environment such as chill - be like wear.
