scope:

This part of ISO 8873 specifies minimum requirements and test methods for spray-applied polyurethane rigid cellular plastic, 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 in-situ thermal insulation. The spray-applied polyurethane rigid cellular plastic thermal insulation shall not be used when the continuous service temperature of the substrate is outside the range of -60 °C to +80 °C. 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. Spray-applied polyurethane rigid cellular plastic shall be applied (installed) in accordance with the manufacturer's instructions and ISO 8873-2 Rigid cellular plastic - Spray polyurethane foam - Application and Installation. Applications, requirements for applications and limitations of use are included in the ISO 8873-2. The testing and evaluation of a product against this International 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.
