ASTM D3747 Standard Specification for Emulsified Asphalt Adhesive for Adhering Roof Insulation
ASTM D3747 粘合屋顶绝缘用乳化沥青粘合剂

This specification covers emulsified asphalt adhesive for use in adhering preformed roof insulation to steel roof decks of specified inclines. When applied as a continuous film over an acceptable deck surface, the emulsion functions as both an adhesive and a vapor retarder. The adhesives shall be appropriately sampled and tested, and shall adhere accordingly to the following physical requirements: water vapor permeance; adhesive strength; freezing resistance; density; residue by evaporation; ash content of residue; and behavior during heat test.

It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope
1.1 This specification covers emulsified asphalt adhesive for use in adhering preformed roof insulation to steel roof decks with inclines up to 33 %. When applied as a continuous film over an acceptable deck surface, the emulsion functions as both an adhesive and a vapor retarder.
1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.
1.3 The following precautionary caveat pertains only to the test method portion, Section 5, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use.
