10、06 All rights reserved Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in
11、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 take part in the work. ISO collaborates closely with the International Electrotechnical Commissi
12、on (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 is to prepare International Standards. Draft International Standards adopted by the technical c
13、ommittees 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 possibility that some of the elements of this document may be the subject of patent rights. ISO shall n
14、ot be held responsible for identifying any or all such patent rights. ISO 8873-1 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 10, Cellular plastics. This first edition of ISO8873-1, together with ISO8873-2 and ISO8873-3, cancels and replaces ISO 8873:1987, which has been
15、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 Part 2: Application Part 3: Test methodsISO 8873-1:2006(E) ISO 2006 All rights reserved v Introductio
16、n ISO 8873 defines the requirements for rigid cellular plastic spray polyurethane foam when used as a thermal insulation in buildings and non-buildings. This part of ISO8873 specifies requirements for the physical properties of rigid cellular plastic spray polyurethane foam and lists the test method
17、s to be used. The designer has the responsibility for confirming that the physical properties provided by material manufactured to this part of ISO 8873 will conform to the requirements for a specific application vi INTERNATIONAL STANDARD ISO 8873-1:2006(E) ISO 2006 All rights reserved 1 Rigid cellu

This document does not purport to address all of the safety concerns, if any, associated with its
19、use. It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any regulatory requirements. 1S c o p e This part of ISO 8873 specifies minimum requirements and test methods for spray-applied polyurethane rigid cellular plastic, used as a
20、thermal insulation for both building, whether applied on a building site or in a prefabrication (manufacturing) facility, and non-building applications. The material is also known as in-situ thermal insulation. The spray-applied polyurethane rigid cellular plastic thermal insulation is not to be use
21、d when the continuous service temperature of the substrate is outside the range of to . 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
22、 control. They are not intended to predict end-use product performance. Spray-applied polyurethane rigid cellular plastics are to be applied (installed) in accordance with the manufacturers instructions and the requirements of ISO 8873-2. Applications, requirements for applications and limitations o
23、f use are included in ISO 8873-2. 2 Normative references The following referenced documents are indispensable for the application of this document.
