1Introduction
1.1Scope.GMW3136covers the requirements for automotive safety glazings.T ypical applications in-clude the entire vehicle glazing and sunroofs.
Other automotive glass(mirrors,bulbs,lens,etc.) does not fall within the realm of this specification.
Rain nsors,solar nsors etc.are outside the lim-its of the glass specification.A interface control doc-ument should be ud.The nsors should have their own specifications.
GMW3160contains the corresponding test methods. The appropriate paragraph numbers of that document are referenced in parenthes in this document’s c-tion titles.
The international standards will be ud wherever possible.
•All glazing must fulfill the requirements of regional legal standards such as ECE R43and MVSS205.
1.2Mission/Theme.This document is the GM Worldwide Glazing Standard.This document defines all common GM Worldwide requirements for automo-tive glazings,and supercedes GM3949M.European regional specific requirements are stated in GME 01101.This is a living document.The document and any suggestions or revisions will be reviewed and/or updated annually by the Glazing T echnical Committee.
1.3Classification.This document is applicable to all automotive glazing including the following types and class:
1.3.1Class A:Laminated Safety Glass.This glass consists of two layers of float glass which are held t
ogether by an intervening layer of automotive grade plasticized polyvinyl butyral(PVB)sheeting.The sheeting material may be clear,tinted or shadeband colored.
1.3.2Class B:Tempered Safety Glass.This glass consists of a single sheet of float glass subjected to a specific heat treatment or tempering process to pro-duce safety characteristics.Due to internal stress t up by the tempering process,any attempt to fur-ther cut,drill,or edge after treatment will cau frac-ture.All glass relead to this specification will be MVSS205and ECE R43compliant.
1.3.3Class C:Glass-Plastic Safety Glazing.A laminate of one or more layers of glass and one or more layers of plastic in which a plastic surface of the glazing faces inward when the glazing is installed in
a vehicle.
1.3.4Class D:Plastic Safety Glazing.Glazing comprid of single or multiple layers of plastic materials,as specified on the engineering drawing.
1.3.5Type1:Clear Safety Glazing.Clear safety glazing has no added tints.
1.3.6Type2:Tinted Safety Glazing.Tinted safety glazing is any color other than clear and generally ha
s specified physical properties,such as reduced light transmittance or incread absorption of solar energy. Tinted glazing is available for all class of glazing.
1.3.7Type3:Privacy Glazing.All class of glazing with or without a vacuum deposited or fired-on metal-lic reflective film.Visible light transmittance is below the70%FMVSS205requirement(e T ransmission chart in3.
2.1.1).The windows are only allowed in certain areas as defined by legal standards.
1.3.8Type4:Solar Control Glazing.This type of glazing is designed to reflect and/or absorb ultravio-let and infrared light while maintaining visible light re-quirements.Two(2)of the types ud are:
1.3.8.1Type4A:Reflective Glazing.Reflective glazing(coated)is comprid of a clear or a tinted layer of glazing with a single or multilayer metallic reflective coating or infrared-reflective foil.
1.3.8.2Type4B:Absorbing Glazing.The absorb-ing characteristics of the glazing material result from the homogeneous composition of the material.
1.3.9Type5:Roof Glazing.Roof glazing is any glazing forming or replacing any portion of the roof,in-cluding sunroofs,moonroofs,T-tops,and Vista Vents.
1.3.10Heated Glass.Typically designed for de-icing and/or defogging windows.
Glazing with a conductive silkscreen pattern normally ud to defrost or defog.Color of silk-screened ma-terial,as viewed from the outside of the vehicle,must match the master sample.Color values to be deter-mined.
lateautumnNote:In the event of a conflict between the text of the specification and the documents cited hereinafter,the text of the specification takes precedence.Nothing in the specification superdes applicable laws and regulations unless a specific exemption has been ob-tained.
Note:In the event of a conflict between the Eng-lish and the domestic language,the English language shall take precedence.

3Requirements
Throughout this ction,parenthetical numerical ref-erences in the ction titles refer to the corresponding ctions of the Verification document(GMW3160). All glazing materials shall be homolagated to FMVSS 205or ECE R43legal standards.If the vehicle is ex-ported,the glazing must meet any legal requirements for the country in which it will be sold.
3.1System/Subsystem/Component/Part Defi-nition.
3.1.1Appearance.
