Standard Test Method for Windload Resistance of Rigid Plastic Siding

Importancia y uso:

5.1 This test method is a standard procedure for determining windload resistance of rigid plastic siding under specified uniform static pressure difference. This typically is intended to represent the effects of wind loads on exterior building surfaces. The actual loading on building surfaces is quite complex, varying with wind direction, time, height above ground, building shape, terrain, surrounding structures, and other factors.

5.2 Design wind pressure is derived for specific geographical locations from wind velocity maps prepared by various agencies and found in references such as ASCE 7, the International Residential Code, International Building Code or other sources. For additional detailed information relating to the use of this test method for evaluation of wind load resistance, refer to Annex A1 of the standard specification appropriate for the type of polymeric siding.

Note 2: In applying the results of this test method, note that the performance of rigid PVC siding is a function of installation, and the specimen may or may not truly represent the actual application. In service, performance will also depend on the rigidity of supporting construction, and on the resistance of other components to deterioration by various causes, to thermal expansion and contraction, etc.
