General Technical Requirements for Glazing Materials Used
in Power-Driven Vehicles
1 Scope
This Document specifies the terms and definitions, classification, technical requirements, test
methods, inspection rules, packaging, transportation and storage for glazing materials used in
power-driven vehicles.
This Document applies to glazing materials used in power-driven vehicles including Types-M,
-N, -O, and -L vehicles with cabs, as well as agricultural and forestry special vehicles.
This Document does not apply to glass for power-driven vehicle lighting and signal devices
and instrument panels.
Note. For the classification of Types-L, -M, -N, and -O vehicles, see GB/T 15089.

and curved glazing materials used in power-driven vehicles. Curved glazing materials used in
power-driven vehicles is further divided into single curved glazing materials used in power-
driven vehicles and compound curved glazing materials used in power-driven vehicles.
5 Technical Requirements
5.1 General
5.1.1 Laminated safety glass, plastic-glass safety glazing material and tempered safety glass are
applicable to any part of a power-driven vehicle. When tempered safety glass is used for the
windscreen, it is only applicable to vehicles with a design speed of less than 40 km/h; insulating
safety glazing unit, rigid plastic glazing pane and insulating rigid plastic glazing panes unit are
applicable to any glass panes other than windscreen.
5.1.2 The glazing materials used in power-driven vehicles that are used as a substrate of safety
glazing faced with plastic material shall comply with the provisions of the corresponding
clauses of this Document. The functional film used for safety glazing faced with plastic material
shall comply with the requirements of QC/T 1170.In addition to meeting the requirements
specified in this Document, the safety glazing faced with plastic material shall also meet the
requirements of GB/T 31849.
5.1.3 The glazing materials used in power-driven vehicles constituting safety insulating safety
glazing unit shall also meet the corresponding technical requirements specified in this
Document.
5.1.4 When the glazing materials used in power-driven vehicles claim to have other functional
characteristics other than the inspection items specified in this Document, such as color change,
anti-theft, sound insulation, heat insulation or bulletproof, etc.; the functional characteristics
shall meet the requirements of the corresponding functional product standards. If there is no
corresponding product standard for the functional characteristics, it shall be agreed upon by the
supplier and the purchaser.
5.1.5 The windows of Types-M1 and -N1 vehicles should meet the Class I requirements in
terms of size deviation, curvature tolerance, overlap difference, appearance quality and edge
quality.
5.2 Thickness deviation
The thickness tolerance range of glazing materials used in power-driven vehicles should meet
the requirements of Table 1.If there are special requirements, the appropriate tolerance range
can be formulated with reference to GB 11614 or agreed upon by the supplier and the purchaser. <...
