Standard Test Method for Water Penetration of Metal Roof Panel Systems by Static Water Pressure Head

Importancia y uso:

5.1 This test method is a standard procedure for determining water leakage through metal roof panel system sideseams, endlaps, and roof plane penetrations when the roof system is subjected to a specified static water pressure head.

Note 2: In applying the results of tests by this method, note that the performance of a roof or its components or both, is in part a function of proper installation and adjustment. In service, the performance will also depend on the integrity of the supporting construction, roof slope, and on the resistance of components to deterioration by various causes: corrosive atmosphere, aging, ice, vibration, thermal cycling, etc. It is difficult to simulate the identical complex wetting, aging, and other variable conditions that can be encountered in service, including wind-blown ponded water; the effects of temperature and age on sealant performance; differential pressure across the joints due to wind, snow, and ice accumulation; densification and migration; and abrasions within the joint components which may occur during thermal cycling and other weather events. Some joint conditions are more sensitive than others to these factors.

5.2 This test method will evaluate the resistance of roof panels, sideseams, endlaps, and roof plane penetrations to water submersion. It will not evaluate panel resistance to wind driven rain.

Note 3: See Test Method E1646 for a test which evaluates resistance to wind driven rain.

5.3 This test method is not a structural adequacy test.

5.4 This test method is applicable to single skin metal panels, the exterior skin of factory assembled composite panels, and the exterior skin of field assembled composite systems as long as means can be provided to distinguish leakage through the exterior panel sideseams/endlaps and perimeter leakage.
