1. Scope
1.1 This specification provides the physical property requirements and test methods to determine these properties for medium-density closed-cell spray-applied rigid polyurethane foam used as an air barrier material in buildings, whether applied on a building site or in a prefabrication (manufacturing) facility. 1.2 The medium-density closed-cell spray-applied rigid polyurethane foam shall only be manufactured/produced/installed in accordance with the spray polyurethane foam system manufacturers instructions. Responsibilities of the manufacturer, the contractor, and the installer are set out by the manufacturer. 1.3 The spray polyurethane foam system manufacturer does not actually produce the medium-density closed-cell spray-applied rigid polyurethane foam material identified by this specification. What the spray polyurethane foam system manufacturer does produce is a liquid resin component that when combined with the corresponding polymeric isocyanate on a fixed ratio basis (normally one to one) subsequently produces, upon installation, the material that shall provide the physical properties listed in this specification. Therefore, the requirements set out by the manufacturer for installation, including requirements for the qualification of contractors and installers, forms an integral part of the manufacturing process for the finished product. Only when the product is produced on site by the installation process set out by the manufacturer is the material able to meet the requirements of this specification. 1.4 The test methods listed in this specification are used to determine the values for the physical properties. These physical property values are intended for use in specifications, product evaluations, and quality control. They are not intended to predict end-use product performance. 1.5 The medium-density closed-cell spray-applied rigid polyurethane foam shall not be used when the continuous service temperature of the substrate is outside the range of 60 to +80C. 1.6 Only metric SI units of measurement are used in this specification. If a value for measurement is followed by a value in other units in parentheses, the second value may be approximate. The first stated value is the requirement. 1.7 The testing and evaluation of a product against this specification may require the use of materials or equipment or both 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.
