Industrial identification Environmental tests
Marking materials and their markings must be particularly resilient depending on their area of application . To ensure clear and durable identification , the properties of the base material must not be able to change too drastically . The quality of the printing must remain constant . Phoenix Contact strictly uses tested materials that fulfill the requirements set by various standards in every respect .
Flammability rating : UL 94
UL 94 describes the fire behavior of materials . During UL 94 V0 / 1 / 2 testing , the test bar is clamped vertically and a flame is applied every 10 seconds . Between each application , the time it takes until the test bar is extinguished , the afterburning time , and the drip behavior are evaluated . If the test bar burns after each application of a flame and the cotton batting below the test bar does not ignite , a flammability rating of V0 is assigned and the material is classified as self-extinguishing .
