Foreword
This Standard is an equivalent standard of Japanese Standard JIS R3205.1989 Laminated glass in technical contents; and it makes reference to ANSI
Z97.1.1984 Safety glazing materials used in buildings - Safety performance specifications and methods of test, ISO/DIS 12543-1~12543-6.1997 Glass in building - Laminated glass and laminated safety glass, AS/NZS 2208.1996 Safety glazing materials in buildings, etc.
This Standard is the first revision of the 1988 edition. The revised contents are as follows.
ADD the laminated glass of category II on the basis of reserving the original laminated glass of categories I and III. ADD the following four indicators. visible light transmittance, visible light reflectance, moisture resistance and wind pressure resistance. Except the moisture resistance, the other three items are recommended indicators. The impact resistance is renamed falling ball impact stripping performance. The penetration resistance is renamed grape-shot bag impact performance. In the meantime, MAKE appropriate modifications to the technical requirements and test methods of some test items.
In the revised standard, the radiation resistance, heat resistance and falling ball impact stripping performance are equivalent to the Japanese Standard JIS R3205; the grape-shot bag impact test adopts the requirements of the American Standard ANSI Z97.1; the moisture resistance test is equivalent to ISO/DIS 12543-4.
The Appendixes A and B of this Standard are normative appendixes.
This Standard replaces GB 9962-1988 from the date of implementation.
This Standard was proposed by State Bureau of Building Materials Industry. This Standard shall be under the jurisdiction of the Glass Science Research Institute of China Building Materials Academy.
Drafting organization of this Standard. Glass Science Research Institute of China Building Materials Academy.
Main drafters of this Standard. Chen Zhengke, Han Song, Wang Ruyang, Wang Le and Hu Yue.

3 Definitions
This Standard uses the following definitions.
3.1 Laminated glass
It refers to the glass products produced by putting the interlayer in between one layer of glass and one or more layers of glass or plastic materials.
3.2 Interlayer
It refers to the materials playing the roles of bonding and isolation between glass or between glass and plastic materials, so as to ensure that the laminated glass has resistance to impact, solar control and sound insulation.
3.3 Laminated glass of category I
It refers to the laminated glass making no requirements for the grape-shot bag impact test.
3.4 Laminated glass of category II-1
It refers to the laminated glass with the grape-shot bag impact height of 1,200mm and conforming to the provisions of Section 5.11.
3.5 Laminated glass of category II-2
It refers to the laminated glass with the grape-shot bag impact height of 750mm and conforming to the provisions of Section 5.11.
3.6 Laminated glass of category III
It refers to the laminated glass with the total thickness of not greater than 16mm and conforming to the provisions of Section 5.11.
4 Classification
4.1 CLASSIFY in accordance with shapes.
For the multilayer products, the products with the total raw glass thicknesses of greater than 24mm, and the products using tempered glass as raw glass, the thickness tolerances shall be agreed by the supply and requisitioning parties. 5.3.3.1 Thickness deviation of dry laminated glass
The thickness deviation of dry laminated glass cannot exceed the sum OF the tolerances of the raw glass sheets constituting laminated glass AND the interlayer tolerances. When the total interlayer thickness is less than 2mm, the tolerances shall not be taken into consideration. When the total interlayer thickness is greater than 2mm, the tolerances shall be ?? 0.2mm.
5.3.3.2 Thickness deviation of wet laminated glass
The thickness deviation of wet laminated glass cannot exceed the sum OF the tolerances of the raw glass sheets constituting laminated glass AND the interlayer tolerances.
For the interlayer tolerances, SEE Table 5.
Table 5 Wet Laminated Glass - Interlayer Tolerances
5.3.4 Diagonal deviation
For the products made of rectangular laminated glass, when the side length is less than 2,400mm, the diagonal deviation shall not be greater than 4mm; when the side length is greater than 2,400mm, the diagonal deviation shall be agreed by the supply and requisitioning parties.
5.4 Flexibility
The flexibility of flat laminated glass shall not be greater than 0.3%. The flexibility of the laminated glass made of wired glass or tempered glass shall be agreed by the supply and requisitioning parties.
5.5 Visible light transmittance
The visible light transmittance shall be agreed by the supply and requisitioning parties. TAKE three test samples for testing. The three test samples are considered to be qualified when all of them conform to the requirements. mm
Interlayer thickness d Tolerance ??
5.6 Visible light reflectance
The visible light reflectance shall be agreed by the supply and requisitioning parties. TAKE three test samples for testing. The three test samples are considered to be qualified when all of them conform to the requirements. 5.7 Heat resistance
The test samples are allowed to have cracks after the test. However, no bubbles or other defects can generate in the sections that are 13mm beyond the edges or cracks.
TAKE three test samples for testing. The three test samples are considered to be qualified when all of them conform to the requirements. When one of them fails to conform to the requirements, the three test samples are considered to be unqualified. When the second test sample conforms to the requirements, CONDUCT additional test to three new test samples. The three test samples are considered to be qualified when all of them conform to the requirements. 5.8 Moisture resistance
After the test, no bubbles or other defects can generate in the sections that are 15mm beyond the original edges, 25mm beyond the new trimming, and 10mm
beyond the cracks.
TAKE three test samples for testing. The three test samples are considered to be qualified when all of them conform to the requirements. When one of them fails to conform to the requirements, the three test samples are considered to be unqualified.
