DIN ISO 17449:2017-10

The International Standard ISO 17449:2015 has been prepared by ISO/TC 22 "Road vehicles", Subcommittee SC 35, "Lighting and visibility" and has been adopted without change in this German standard. This International Standard provides the test methods and acceptance criteria for circuit continuity and heating power, driving visibility, electrical attachment bond performance, electrical attachment bending performance, hot spot identification and heating uniformity, defrosting efficiency, high voltage durability, low temperature performance and long term humidity durability, for all electrically heated safety glazing materials in a road vehicle. This International Standard provides test protocols for the static performance of an electrically heated glazing material; it is not representative of in-vehicle performance. The responsible German standardization committee is Working Committee NA 062-03-61 AA "Prüfung von Sicherheitsscheiben für Fahrzeugverglasung" ("Testing of safety glass constructions used in vehicle glazing") at DIN Standards Committee Materials Testing (NMP).
