Over deze norm
1.1 This laboratory test method covers the determination of the resistance to water penetration of exterior metal roof panel system sideseams, endlaps, and roof plane penetrations when a specified static water pressure head is applied to the outside face of the roof panel.
Note 1—This test method is intended to evaluate water-barrier (not water-shedding) roof system joints and details. These systems are also referred to as hydrostatic roof systems.
1.2 This test method is limited to specimens in which the sideseams and attachments are clearly visible and in which the source of leakage is readily observable.
1.3 This test method excludes performance at roof perimeter conditions.
1.4 This test method is suitable for evaluating leakage at roof plane penetrations such as fasteners, curbs, pipes, and expansion joints under a static water pressure head.
1.5 The proper use of this test method requires a knowledge of the principles of water pressure.
1.6 The text of this standard includes notes and footnotes excluding tables and figures, which provide explanatory material. These notes and footnotes shall not be considered as requirements of the standard.
1.7 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
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. For specific precautionary statements, see Section 7.
