See Chinese contents: GB/T 43299-2023 GB/T 43299-2023: Test methods of electrical heating properties for glazing materials used in power-driven vehicles
This document describes the test methods of electrical heating properties – circuit conductivity and heating power, driving visibility, electrical attachment pull-off force, electrical attachment bending resistance, hotspot and heating uniformity, defrosting efficiency, overpressure, low temperature electric thermal shock resistance and moisture resistance – for glazing materials used in power-driven vehicles. This document applies to the static property test of electrically heated glazing products and does not represent the properties in the installed state.
