This Standard specifies the requirements and test methods for bead-applied one component polyurethane foam used as an insulating air sealant for both building and non-building applications. This Standard covers bead-applied one-component polyurethane air sealant foam whether applied on a building site or in a prefabrication (manufacturing) process. The one-component polyurethane foam is factory pre-packaged.

The requirements in this Standard apply only to the use of bead-applied one component polyurethane foam when the continuous service temperature is in the range of -60 to +110 °C.

The test methods used to determine the material properties provide a means of comparing different polyurethane air sealant foams. They are intended for use in specifications, product evaluations and quality control.

Applications and requirements for the applications are included in the CAN/ULC-S710.2 Installation Standard.
