6、rength, impact performance, and post-breakagecharacteristics of railing systems, guards, and balustrades, including a component with glass or other glazing material installed inone, two, three and four-side support systems fastened to concrete, masonry, wood, metal, and related products.1.5 No consi
7、deration is given in these test methods to any possible deterioration of the railing, guard, or balustrade system ortheir connections and fasteners as resulting from adverse environmental or in-service conditions. The performance of special testscovering this aspect may be desirable.1.6 These test m
8、ethods are limited to the application of loads and impact resistance described herein. Whenever uniformlydistributed loads are to be resisted by a railing system, guard, or balustrade in accordance with governing specifications, codes,norms, and standards, the effects of such loads on the member str
9、esses shall be determined by calculation and the correspondingconcentrated and linear loads shall be tested. Should computations make it possible to provide the needed information, testing canbe employed for verification.1.7 These test methods address the capability of glass or other glazing materia
