A curb is not required for Group R-3 if the slope of the roof is a minimum of 14 degrees (3:12 slope). If heat-strengthened and fully tempered glass is used monolithically (i.e. For additional requirements for plastic skylights, see Sec-tion 2610. ( �� The standards to test for impact resistance are ASTM E 1886, Test Method for Performance of Exterior Windows, Glazed Curtain Walls, Doors and Storm Shutters Impacted by Missiles and Exposed to Cyclic Pressure Differentials, and ASTM E 1996, Specification for Performance of Exterior Windows, Glazed Curtain Walls, Doors and Impact Protective Systems Impacted by Windborne Debris in Hurricanes. That meant it wasn’t tempered. Identifying Tempered Glass. There will be markings to identify the type of glass used i.e. Fire-rated glass labels include a multitude of information, including the product name, basic characteristics (e.g., tempered, laminated, etc. Each of them possesses distinct performance characteristics. Fire protective glazing cannot limit radiant heat or meet ASTM E-119. Strength involves the idea of resistance to rupture. The IBC has some exceptions to these requirements, and also provides some substitutions that modify the application of ASTM E 1996.3. 1. The proposal's new marking requirements for tempered glass, laminated glass and glass-plastic glass are substantially similar to the marking requirements of ANSI Z26.1. 5, “How You Can Change a Building Code,” for more information on the elimination of the wired glass exemption. The changes in the proposed GTR are only applicable to tempered glass, laminated glass, and glass face plastic glazing. The bottom edge of the glass is less than 18 inches above the floor. It works in a similar fashion to laminated glass by holding shattered glass pieces to the film if broken. 1.2 This standard prescribes the safety requirements to check / minimize / control the injuries of any person accidentally coming in contact with glass. Skylights must be set on a 4-inch curb if the slope of the skylight unit is at an angle of 45 degrees or less from the horizontal. For decades, wired glass was exempt from the impact requirements of CPSC 16 CFR Part 1201 if used in areas where fire-resistance and safety glass was required. Tempered spandrel glass is permitted to be identified by the manufacturer with a … Transparent glass doors and fixed adjacent transparent glass sidelights shall be marked in two areas on the glass surface thereof. About 1% of these are bottles, 1% are glass, and 1% are building glass. Other annealed glass regulations are as follows… 8mm glass can be used as safety glass if it does not exceed 1100mm in any direction 10mm glass can be used as safety glass if it does not exceed 2.25m in any direction Laminated glass with 15-mil interlayer (polyvinyl butyral or equivalent) is permitted without screening if used within dwelling units in Groups R-2, R-3, and R-4, provided no pane is larger than 16 sq. Regardless, none of my glass pieces has a bug mark. Standards ) for tempered glass and heat strengthened glass, that specify, in any EU country, • the requirements of performance characteristics • test methods and declaration of results Glass products intended to be used in building must carry a CE mark, which means that the marked It is a safety glass processed by controlled thermal or chemical treatments to … To qualify as safety glazing, the test specimen must not, at a minimum, develop a hole in which a 4-pound 3-inch solid steel sphere could pass.

Zhao Ping-Wang Qinhuangdao Qicaishi Qifei Chen QinHuangDao Tianrui Tempered Technology Glass Zhu YanJun Cheng Yi Bin Quaker Window Products, Inc. Curtis Weavers Figure 6 - Criteria for safety glazing adjacent to wet areas. For other than tempered glass, manufacturer’s designations are not required provided the building official approves the use of a certificate, affidavit or other evidence confirming compliance with this code. Glass is also being used in more creative applications, generating specialized areas in structural glazing systems. As an example 6mm annealed glass can be used in doors up to a glazing width of 250mm but must not exceed 0.5sq.metre in area. Figure 4 - Exception to requirement for safety glass when partition is between door and adjacent glass. If a glazed opening is within 30 feet of the grade, then the glazing must pass the large-missile test of ASTM E 1996. However, the test method is modified to test an actual installation or an identical assembly, with all the required fixtures and fittings, and the impact point is located at a height of 59 inches above the playing surface.
