Each member body interested in a subject for which a technical committee has been Electrotechnical Commission (IEC) on all matters of electrotechnical standardization International Standards are drafted in accordance with the rules given in the IsO/lEC Directives, Part 2 adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval byat least 75 %of the member bodiescasting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent This first edition of ISO 8873-1,together with ISO 8873-2 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 foamforthermal insulation: Part1:Materialspecifications — Part2:Application Part3:Testmethods ISO8873-1:2006(E) Introduction 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 IsO 8873 specifies requirements for the physical properties of rigid cellular plastic spray polyurethane foamand lists the testmethods 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.
