Abstract
This specification covers mineral granule-surfaced asphalt roofing shingles. Covered here are the self-sealing (Type I) and non-self-sealing (Type II) types of shingles. The shingles shall consist of organic felt or glass mat(s) saturated or impregnated, and coated on both sides with a hot asphaltic material and completely surfaced on the weather side with mineral granules embedded in the coating. The reverse side of the shingles shall be covered with a suitable material to prevent the shingles from sticking together in the package, causing possible damage upon being unpacked at ambient temperatures. Type I shingles shall have a factory-applied adhesive that will seal the shingles together after application. Both types shall meet the conditions for Class A fire exposure, and loss and behaviour on heating tests. Type I shingles shall pass an additional wind resistance test.
