12、ISO 4898:2006(E) iv ISO 2006 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
13、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 take part in the work. ISO collaborates closely with the International
14、 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 is to prepare International Standards. Draft International Standards
15、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 possibility that some of the elements of this document may be the subject of
16、patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 4898 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 10, Cellular plastics. This third edition cancels and replaces the second edition (ISO 4898:2004), which has been technica
17、lly revised.

18、06(E) ISO 2006 All rights reserved 1 Rigid cellular plastics Thermal insulation products for buildings Specifications 1 Scope This International Standard specifies requirements and methods of testing for four categories of rigid cellular plastics thermal-insulation products for buildings. It covers
19、rigid cellular plastics in the form of flat or profiled boards, with or without natural skins. They may also be faced or laminated with foil, plastic or metal films or sheets, mineral coatings, paper, cardboard or other materials. This International Standard is not applicable to materials used for t
20、he thermal insulation of pipes and vessels, for impact sound absorption or for acoustical insulation. This International Standard covers the following cellular materials used in the thermal insulation of buildings: PF based on phenolic polymer; EPS based on expanded polystyrene; XPS based on extrude
21、d polystyrene; PUR based on polyurethane. The limiting quality values in this International Standard are for use only in the specification of materials between purchaser and supplier, and are not intended to be used for design purposes. Additional requirements for special applications may be added t
22、o those specified in this International Standard by agreement between purchaser and supplier. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edi
23、tion of the referenced document (including any amendments) applies.
