1. SCOPE 1.1
This Standard provides the requirements and test methods for spray-applied
rigid polyurethane cellular plastics, medium density, used as a thermal
insulation for both building and non-building applications, whether applied on
a building site or in a prefabrication (manufacturing) facility. The material
is also known as foamed in-situ insulation. 1.2
The spray-applied rigid polyurethane cellular plastic thermal insulation
shall not be used when the continuous service temperature of the substrate is
outside the range of -60 to +80°C. 1.3
The test methods used to determine the material properties provide a means
of comparing different cellular plastic thermal insulations. They are intended
for use in specifications, product evaluations and quality control. They are
not intended to predict end-use product performance. 1.4
Spray-applied rigid polyurethane cellular plastic thermal
insulation-medium density must be applied (installed) in accordance with the
manufacturer's instructions and CAN/ULC-S705.2, Thermal Insulation - Spray
Applied Rigid Polyurethane Foam, Medium Density, Application - Specification by
a licensed contractor using a licensed installer for the actual application.
Applications, requirements for applications and limitations of use are included
in CAN/ULC-S705.2. 1.5
The testing and evaluation of a product against this Standard may require
the use of materials and/or equipment that could be hazardous. This document
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.
