ASTM E2431-06(2011)

Description

1.1 This practice covers a procedure to determine the resistance of annealed architectural flat glass to thermally induced stresses caused by exposure to sun and shadows for a specified probability of breakage (P_b). Proper use of this procedure is intended to reduce the possibility of thermal breakage of annealed glass in buildings.

1.2 This practice applies to vertical or sloped glazing in buildings.

1.3 This practice applies to monolithic and laminated glass of rectangular shape and assumes that all glass edges are simply supported.

1.4 This practice applies only to annealed flat soda-lime silica glass with clean cut, seamed, flat ground, or ground and polished edges that are free from damage. The glass may be clear or tinted as well as coated (not including coatings that reduce emissivity of the glass).

1.5 This practice does not apply to any form of wired, patterned, etched, sandblasted, drilled, notched, or grooved glass or glass with surface and edge treatments, other than those described in 1.4, that alter the glass strength.

1.6 This practice does not address uniform loads such as wind and snow loads, safety requirements, fire, or impact resistance.

1.7 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard. For conversion of quantities in various systems of measurements to SI units refer to IEEE/ASTM SI-10.

1.8 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.
