Norme sur la mousse d'étanchéité à l'air de polyuréthane bicomposant appliquée en cordon, partie 1 : spécifications relatives au matériau

1.1.    This Standard specifies the requirements and test methods for bead-applied two- component polyurethane foam used as an air sealant for both building and non-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 two-component polyurethane air sealant foam are supplied in a pre-packaged, pressurized system.

1.4.    The requirements in this Standard apply only to the use of bead-applied two 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 polyurethane air sealant foams. They are intended for use in specifications, product evaluations and quality control. They are not intended to predict end use product performance.

1.6.    Two-component bead-applied air sealant polyurethane foams are closed cell materials which are installed to a maximum bead size cross section of 100 mm.

1.7.    Products with a captive blowing agent shall undergo long term thermal resistance evaluation.

1.8.    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.
