General technical requirements for glazing materials used in power-driven vehicles
1 Scope
This document specifies terms and definitions, classification, technical requirements, test methods, inspection rules, packaging, transportation and storage of glazing materials used in power-driven vehicles.
This document is applicable to glazing materials used in power-driven vehicles, including M-class, N-class, O-class, L-class vehicles with driver's cab, agricultural and forestry vehicles.
This document is not applicable to glazing materials used for the lighting and signaling devices and instrument panels of power-driven vehicle.
Note: The classification of L-class, M-class, N-class, and O-class vehicles is specified in GB/T 15089.

4 Classification
4.1 The glazing materials used in power-driven vehicles are classified into laminated safety glass, tempered safety glass, insulating safety glazing unit, glass-plastic safety glazing material, rigid plastic glazing pane, insulating rigid plastic glazing panes unit, and safety glazing faced with plastic material according to production and processing technology and/or materials.
4.2 The glazing materials used in power-driven vehicles are classified into windscreen and glass panes other than windsereen according to the application position.
4.3 The glazing materials used in power-driven vehicles are classified into Class I and Class II based on dimensional deviation, curvature tolerance, overlap, appearance quality, and edge quality.
4.4 The glazing materials used in power-driven vehicles are classified into flat glazing materials and curved glazing materials used in power-driven vehicles according to shape. The curved glazing materials used in power-driven vehicles are classified into single curved glazing materials and composite curved glazing materials.
