Foreword
All the technical contents of this Standard are mandatory.
This Standard was formulated by referring to FOCT 21992-1983 Specifications of the Special-Shaped Glass for Construction and EN 57207-1994 Wired and Non-Wired U- Profile Glass. The appearance quality indicator and size specification are formulated by referring to FOCT 21992-1983; while other indicators and inspection methods are formulated by referring to EN 57207-1994. Meanwhile, the bending strength indicator and the inspection method are determined according to the characteristics of U- shaped glass and the domestic product condition.
The Appendix A of this Standard is the standard appendix.
This Standard was drafted and under the jurisdiction of Qinhuangdao Glass Research and Design Institute of State Construction Materials Industry Administration. Participating drafting organization of this Standard. Yunnan Kunming Chuangan U- Shaped Glass Co., Ltd.
Chief drafting staffs of this Standard. Wang Yongheng, Lai Jiahua, and Yang Helu. Construction U Shape Glass

3 Definition
This Standard adopts the following definition.
Construction U shape glass. glass produced mainly by continuous melting, calendaring, forming and annealing glass batch materials.
than or equal to the number of allowable disqualified glass, then such batch of glass is qualified. If the number of the disqualified glass is greater than or equal to the number of disqualified glass for reference, then such batch of glass is disqualified; and the secondary sample is not necessary.
If the number of disqualified glass in each sampling is greater than the number of allowable disqualified glass, but less than the number of disqualified glass for reference, then the secondary sampling is necessary.
7.3.2 If the number of disqualified glass in the accumulated quantity of the two samples is less than or equal to the allowable disqualified glass, then such batch of glass if qualified. If the number of disqualified glass in the accumulated quantity of the two samples is greater than or equal to the number of disqualified glass for reference, then such batch of glass is disqualified.
7.3.3 The metallic wire deviation, wing skewness, visible light transmittance, and bending resistance of the U-shaped glass shall also conform to the provisions of 5.5, 5.6, 5.8, 5.9. Otherwise, such item is considered unqualified.
7.3.4 If one of the above items is unqualified, then such batch of glass is disqualified. 8 Marking, Package, Transportation and Storage
