Over deze norm
1.1 These test methods cover procedures to be followed in testing the performance of glass in permanent railing systems, guards and balustrades installed in and for assembly, commercial, educational, industrial, institutional, stadiums, recreational, and residential buildings.
1.2 These test methods are applicable to such railing, guard, and balustrade systems having glass as the major structural component or the infill panel
1.3 These test methods can be used to determine whether permanent rails, guards and balustrades having a glass component comply with anticipated performance requirements of the applicable specifications, codes, and standards.
1.4 Specifically, these test methods cover procedures for determining the static strength, impact performance, and post breakage retention characteristics of railing systems, guards, and balustrades with a glass component installed in one, two, three and four side support systems that are fastened to concrete, masonry, wood, and metal as well as related products.
1.5 No consideration is given in these test methods to any possible deterioration of the railing, guard, or balustrade system or their connections and fasteners as resulting from adverse environmental or in-service conditions. The performance of special tests covering this aspect may be desirable.
1.6 These test methods are limited to the application of concentrated and linear loads and impact resistance described herein. Whenever uniformly distributed loads are to be resisted by a railing system, guard, or balustrade in accordance with governing specifications, codes and standards, the effects of such loads on the member stresses shall be determined by calculation and the corresponding concentrated and linear loads shall be tested. Should computations make it possible to provide the needed information, testing can be employed for verification.
1.7 These test methods address the capability of glass rails, guards, and balustrades in one, two, three and four sided support systems to continue in their function as a barrier by remaining in the designed framing system after impact or glass breakage. This specification does not address structural limitation of glass rails, guards, and balustrades or vehicular guards except when in the area of a pedestrian walkway.
1.8 All values are stated in SI units and are to be regarded as standard. Values given in parentheses are for information only. Certain values contained in reference documents cited and quoted herein may be stated in inch-pound units and must be converted by the user.
1.9 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
