Historical Version s – view previous versions of standard.

The slope of the roof is significant. These factors shall be fully considered prior to specifying the test pressure difference. In applying the results of tests by this method, note that the performance of a roof or its components, or both, may be a function of proper installation and adjustment.

In service, the performance also depends on asym rigidity of supporting construction, roof slope, and on the resistance of components to deterioration by various causes: It is difficult to simulate the identical complex wetting conditions that can be encountered in service, including large wind-blown water drops, increasing water drop impact pressures with increasing wind velocity, and lateral or upward moving air and astn.

Some designs are more sensitive than others to this upward moving water. This is a test procedure.

Practical considerations suggest that every combination of panel thickness, span, and design load need not be tested in order to substantiate product performance. This test method shall not, by itself, be relied upon to form conclusions about overall water penetration through metal roofs.

ASTM E – Farabaugh Engineering and Testing

A roof contains many details. Although prescribed modifications are outside the scope of this test method, an experienced testing engineer is able to use the principles presented in this test method and generate significant data by isolating specific details and measuring leakage. This test aastm is a specialized adaption of Test Method E It does not include leakage at openings or perimeter or any other details. Composite systems in which the source cannot be readily determined are outside the scope of this test method.
