Classification4.1 TypeLaminated flat glass furnished under this specification shall be of the following types, as specified:4.1.1 Type I - Laminated GlassAn assembly consisting of two or more lites of glass, conforming to Specifications C1036 orC1048,
31、that are bonded together by interlayer material.4.1.2 Type II - Laminated Safety GlassAn assembly of two or more lites of flat glass, conforming to Specifications C1036 orC1048, that are bonded together by interlayer material that meet the requirements ofANSI Z97.1 or CPSC 16CFR1201. In the caseof b
32、reakage, the interlayer serves to retain the glass fragments, limit the size of the opening and reduce the risk of cutting orpiercing injuries.4.2 ApplicationThe following terms are designed to guide the user to the appropriate inspection charts and requirements. Theglazing can usually, but not alwa
33、ys, be viewed in transmittance and reflectance.4.2.1 Laminated Proximate GlazingGlazing used in an installation in which the lower edge of the glazing is a maximum of6 ft (1.8 m) above the walking surface. The glazing is usually vertical, however, may also be sloping in or out from the verticalplane
34、. The glazing can be approached within 10 ft (3 m) or less (if distance is greater than 10 ft (3 m) see Laminated OverheadGlazing). Interior decorative glazing will be judged according to laminated vertical glazing criteria.4.2.2 Laminated Overhead GlazingGlazing used in an installation in which the
35、 lower edge of the glass is more than 6 ft (1.8m) above a walking floor level or cannot be approached within 10 ft (3 m). The glazing is usually sloping from the vertical plane,however, may also be vertical. Sloped glazing is considered any glazing that slopes more than 15 from the vertical in anydi
36、rection.4.2.3 Laminated Spandrel GlazingGlazing used in an installation in which the glazing is only viewed in reflection from thebuildings exterior. The glazing is usually installed vertically, however, may be at a slope to the vertical plane. Laminated spandrelglazing shall be inspected using the
37、criteria of laminated proximate glazing or laminated overhead glazing as defined in 4.2.1 or4.2.2.5.
