ICS 81.040.20 CCS Q 33 National Standard of the People’s Republic of China GB/T 15763.3-2025 Replaces GB/T 15763.3-2009 Safety glazing materials in building - Part 3: Laminated glass 建筑用安全玻璃 第3部分:夹层玻璃 (English translation) Issue date: 2025-10-31 Implementation date: 2026-08-01 Issued by the State Administration for Market Regulation of the People's Republic of China the Standardization Administration of the People's Republic of China Safety glazing materials in building Part 3: Laminated glass 1 Scope This document specifies the classification, requirements, inspection rules, packaging, transportation and storage，and describes the test methods of laminated glass used in building. This document applies to the design, production and delivery of laminated glass used in building. For laminated glass used outside buildings (such as industrial equipment and furniture, etc.), if there is no corresponding product standard, this document shall be used for reference according to the product characteristics. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this document. For dated references, only the edition cited applies. For undated references, the latest edition (including any amendments) applies. GB/T 2680 Glass in building - Determination of light transmittance, solar direct transmittance, total solar energy transmittance, ultraviolet transmittance and related glazing factors GB/T 5137.2 Test methods of safety glazing materials used on road vehicles - Part 2: Optical properties tests GB/T 8170 Rules of rounding off for numerical values & expression and judgement of limiting values GB/T 8485 The graduation and test for airborne sound insulating properties of windows and doors GB 11614 Flat Glass GB 15763.2-2025 Safety glazing materials in building - Part 2 : Tempered glass GB/T 37825 Test method for simulating wind pressure resistance of building glass under the uniform static loads 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 interlayer material interposed between two layers of glass and/or plastic for separation and bonding, thereby providing laminated glass with properties such as impact resistance, solar control, and sound insulation 3.2 ionoplast interlayer intermediate layer material primarily composed of ethylene-methacrylic acid copolymer, containing trace amounts of metal salts, and capable of forming a robust bond with glass 3.3 PVB interlayer intermediate layer material primarily composed of polyvinyl butyral 3.4 EVA interlayer intermediate layer material primarily composed of ethylene-vinyl acetate copolymer Note: Including low-crosslinked EVA and high-crosslinked reinforced EVA (PVE). 3.5 laminated glass general term for a composite material consisting of glass and/or plastics, which are separated by intermediate layers and bonded together through processing Note: The most common and widely used form is a glass element where glass panes are separated and bonded together by an interlayer through processing. 3.6 symmetrical laminated glass laminated glass in which the materials such as glass and/or plastic, interlayers, from the two outer surfaces inward, are identical in type, thickness, and/or general features 3.7 asymmetrical laminated glass laminated glass in which the materials such as glass and/or plastic, interlayers, from the two outer surfaces inward, are identical not in type, thickness, and/or general features 3.8 edge area area within 15 mm from the edges when the area is ≤ 5 m², or within 20 mm from the edges when the area is > 5 m² 3.9 vision area area excluding the edge area 3.10 vent sharp linear crack extending from the glass edge to the middle 3.11 crease optical deformation visible after lamination caused by interlayer folding 3.12 streak visible optical deformation after lamination due to inhomogeneity defect in the manufacturing process of the interlayer materials 3.13 delamination separation caused by the localized loss of adhesive force between the glass or plastic and the interlayer 3.14 spot defect opaque spots, bubbles and spot foreign matters 3.15 linear defect linear foreign matters, scratches or abrasions 3.16 bubble visible gas inclusions formed within the interlayers or on the interfaces between the interlayers and the glass 3.17 cloudiness hazing phenomenon in which the scattering of incident light by the specimen reduces its direct light transmittance, resulting in a cloudy or overall milky appearance 3.18 discoloration obvious change of colors of laminated glass due to oxidation of the interlayer Note: Discoloration of transparent interlayers is typically considered as yellowing. 4 Classification 4.1 By shape a) Flat laminated glass; b) Curved laminated glass. 4.2 By shot-bag impact performance a) II-1 laminated glass; b) II-2 laminated glass; c) III laminated glass. Note: for the recommendations for the use of safety glass in buildings, see Annex A 4.3 By resistance to heat a) L laminated glass; b) S laminated glass; 5 Requirements 5.1 General 5.1.1 Laminated glass is composed of a combination of glass, plastics, and interlayer materials (such as ionic interlayers, PVB interlayers, EVA interlayers, etc.). All materials used shall comply with the corresponding national standards, professional standards, relevant technical specifications, or requirements stipulated in the ordering documents. 5.1.2 Laminated glass with special functions shall comply with the provisions of clauses 5.2 ~ 5.11, and may also comply with the relevant provisions in 5.12 ~ 5.14 according to its functions. 5.2 Dimension and deviation 5.2.1 Edge length deviation The edge length deviation of laminated glass shall meet those specified in Table 1.
