CAN/ULC S705.1- 01 with August 2004 Amendment - Standard for Thermal Insulation - Spray Applied Rigid Polyurethane Foam, Medium Density - Material - Specification

The following is the scope and the basic requirements of this standard. To purchase UCL Standards, please visit the following web address and choose ULC Online Store: www.ulc.ca

1. SCOPE

1.1  This Standard specifies 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.
