description abstract	The test described in this standard is applicable to prepared roof coverings which comply with the requirements for construction, material specifications, and performance, including fire resistance, as applicable to specific types, designs, sizes, and arrangements of roof coverings which are intended, when properly installed, to resist damage when subjected to winds in the Beaufort Scale No. 10 range [55 - 63 mph (88 - 101 Km/h)]. Materials complying with these requirements are not expected to withstand the wind forces of tornados, cyclones, or hurricanes. Wind-resistance capabilities of prepared roof coverings are usually obtained by utilizing a factory-applied or field-applied adhesive or an interlocking construction. As used in this standard, the term "prepared roof covering material" includes but is not limited to asphalt shingles and formed metal shakes and shingles.
