1.1 This Standard specifies the physical property requirements and test methods to determine the
material properties for light density, open cell spray applied semi-rigid polyurethane foam, used as a
thermal insulation for building applications, whether applied on a building site or in a prefabrication
(manufacturing) facility.
1.2 The spray polyurethane foam system installer site manufactures the light density, open cell spray
applied semi-rigid polyurethane foam material identified by this Standard. The spray polyurethane foam
system manufacturer produces a liquid “resin” component and supplies the corresponding polymeric
isocyanate which, when mixed together on a fixed ratio basis, produce the material which results in the
physical properties listed in this Standard. The Standard CAN/ULC-S712.2 includes mandatory
requirements for the installation of the material as well as qualification of contractors and the qualification
of installers and forms an integral part of the manufacturing process for the finished material.
1.3 The test methods listed in this Standard are used to determine the values for the physical properties.
These physical property values are intended for use in specifications, material evaluations and quality
control. They are not intended to predict end-use material performance.
1.4 This standard applies to material where the continuous service temperature of the substrate is within
the range of -60 to +70 °C.
1.5 The testing and evaluation of a material against this Standard may require the use of materials and/or
equipment that could be hazardous. This Standard does not purport to address all the safety aspects
associated with its use. Anyone using this Standard has the responsibility to consult the appropriate
authorities and to establish appropriate health and safety practices in conjunction with any existing
applicable regulatory requirements prior to its use.
