Two or more lites of flatglass, bonded by interlayer material. In

26、 the case of breakage,the interlayer serves to retain the glass fragments, limit the sizeof the opening and reduce the risk of cutting or piercinginjuries.4.2 Application the following terms are designed to guidethe user to the appropriate inspection charts and requirements.The glazing can usually,

27、but not always be viewed in transmit-tance and reflectance.4.2.1 Laminated Vertical GlazingGlazing used in an in-stallation in which the lower edge of the glazing is a maximumof 1.8 m (6 ft) above the walking surface. The glazing isusually vertical, however may also be sloping in or out fromthe vert

28、ical plane. The glazing can be approached within 3 m(10 ft) or less (if distance is greater than 3 m (10 ft) seeLaminated Overhead Glazing). Interior decorative glazing willbe judged according to laminated vertical glazing criteria.4.2.2 Laminated Overhead GlazingGlazing used in aninstallation in wh

29、ich the lower edge of the glass is more than1.8 m (6 ft) above a walking floor level or cannot beapproached within 3 m (10 ft). The glazing is usually slopingfrom the vertical plane, however may also be vertical. Slopedglazing is considered any glazing that slopes more than 15degrees from the vertic
