ASTM E1646

Water Penetration Test
ASTM E1646 is the standard test method for water penetration of exterior metal roof panels by uniform static air pressure difference.  The ASTM E1646 test method covers the determination of the resistance of exterior metal roof systems to water penetration when water is applied to the outdoor face simulatenously with a static air pressure at the outdoor face higher that the pressure at the indoor face.
