1.1 This Standard specifies the requirements and test methods for bead-applied one component
polyurethane foam used as an air sealant for building applications. The materials covered under this
Standard may be applied on a building site or in a prefabrication (manufacturing) process.
1.2 This Standard does not address the requirements for this material to be used as a thermal insulation
or as fire blocking material.
1.3 The components for the one component polyurethane air sealant foam are supplied in a prepackaged,
pressurized system.
1.4 The requirements in this Standard apply only to the use of bead-applied one component
polyurethane air sealant foam when the continuous service temperature is in the range of -60 ° C to
+80 °C.
1.5 The test methods used to determine the material properties provide a means of comparing different
one component polyurethane air sealant foam. They are intended for use in specifications, product
evaluations and quality control. They are not intended to predict end use product performance.
1.6 One-component bead-applied polyurethane air sealant foams are open cell materials which are
installed to a maximum bead size cross section of 25 mm.
1.7 This document does not purport to address all the health and safety aspects associated with its use.
Anyone using this Standard has the responsibility to consult the appropriate authorities and to establish
health and safety practices, in conjunction with any existing applicable regulatory requirements, prior to its
use.
