The work of preparing International Stan
13、dards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also t
14、ake part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees
15、is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibil
16、ity that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 8873-2 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 10, Cellular plastics. This first edition of ISO 88
17、73-2, together with ISO 8873-1 and ISO 8873-3, cancels and replaces ISO 8873:1987, which has been technically revised. ISO 8873 consists of the following parts, under the general title Rigid cellular plastics Spray-applied polyurethane foam for thermal insulation: Part 1: Material specifications Par
18、t 2: Application Part 3: Test methods ISO 8873-2:2007(E) ISO 2007 All rights reserved v Introduction Spray polyurethane foam for thermal insulation is made by combining two liquid components on the project site to manufacture a product. As the manufactured product is what provides the physical and t
19、hermal properties desired by the user, it only becomes spray polyurethane foam when it is installed. As such, an International Standard for the application and installation is required. This part of ISO 8873 outlines the obligations for the installer of the liquid components that produce the actual
20、material. ISO 8873-1 outlines obligations for the manufacturers of spray polyurethane foam liquid components. ISO 8873-3 provides test methods which have not previously been specified in International Standards. INTERNATIONAL STANDARD ISO 8873-2:2007(E) ISO 2007 All rights reserved 1 Rigid cellular
21、plastics Spray-applied polyurethane foam for thermal insulation Part 2: Application WARNING Persons using this document should be familiar with normal laboratory practice, if applicable. This document does not purport to address all of the safety concerns, if any, associated with its use. It is the
22、responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any regulatory requirements. 1 Scope This part of ISO 8873 outlines requirements for the application of rigid cellular plastic spray polyurethane foam for thermal insulation. The primary app
23、lication of the material is for use as thermal insulation. Spray polyurethane foam can also be used as the air barrier material which forms part of an air barrier assembly in buildings. Under specific application conditions, the material can be used in vapour barrier applications in a building assem
24、bly (details of the conditions can be obtained from the manufacturer). The application requirements are for the installation of spray polyurethane foam whether applied on a building site or in a prefabrication (manufacturing) facility. This part of ISO 8873 can be used for non-building applications
25、when agreed to by the supplier and the purchaser. The requirements include obligations for the manufacturer, the contractor and the installer. The requirements include the selection of chemical components, application requirements, quality control and documentation of the application, limitations fo
26、r the application and requirements for safety and for disposal of associated waste material and packaging. Installation of spray polyurethane foam for thermal insulation, according to this part of ISO 8873 requires the use of materials and/or equipment that could be hazardous (see Warning). 2 Normat
