Rigid cellular plastics - Spray-applied polyurethane foam for thermal insulation - Part 1: Material specifications

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, 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 used 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 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
manufacturer's instructions and the requirements of ISO 8873-2. Applications, requirements for applications
and limitations of use are included in ISO 8873-2.

Ta del standarda ISO 8873 določa minimalne zahteve in metode preskušanja za brizgano poliuretansko peno iz penjenega polimernega materiala, ki se uporablja kot toplotna izolacija v stavbah, ne glede na to, ali se uporablja na gradbišču ali v montažnem (proizvodnem) obratu, ali zunaj stavb. Material se imenuje tudi toplotna izolacija, izdelana na kraju samem.
Toplotna izolacija iz brizgane poliuretanske pene iz penjenega polimernega materiala se ne sme uporabljati, če je razpon stalne delovne temperature podlage zunaj območja do .
Metode preskušanja, uporabljene za določanje lastnosti materialov, zagotavljajo način za primerjavo različne toplotne izolacije iz brizgane poliuretanske pene. Namenjene so za uporabo pri specifikacijah, vrednotenju proizvodov in kontroli kakovosti.
Niso namenjene za napovedovanje lastnosti končnega proizvoda.
Brizgana poliuretanska pena iz penjenega polimernega materiala se mora uporabljati (namestiti) v skladu z
navodili proizvajalca in zahtevami iz standarda ISO 8873-2. Uporabe, zahteve za uporabo in omejitve uporabe so vključene v standard ISO 8873-2.

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 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 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

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 patent

rights. ISO shall not 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 technically revised.

ISO8873 consists of the following parts, under the general title Rigid cellular plastics— Spray-applied
