Windshield, defogging

All vehicles with cabs shall be equipped with windshields and powered wipers. Cracked and broken glass shall be replaced. Vehicles operating in areas or under conditions that cause fogging or frosting of the windshields shall be equipped with operable defogging or defrosting devices. [Pg.590]

Indium is a soft malleable, silvery white metal. Due to its low friction properties, it is used in bearing alloys. Certain indium compounds have unique semiconductor properties. Films of ITO, indium-tin oxide (80% In Oj), are transparent to visible light but not for infrared light. In addition they have good electrical conductivity. The electrical conductivity of the thin coating is utilized on windshields for railway locomotives and airplanes to make it possible to warm them up with electric current for defogging. [Pg.850]
