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
polyurethane foam for thermal insulation:

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 ISO8873 specifies requirements for the physical properties of rigid cellular plastic spray
polyurethane foam and lists the test methods 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.

INTERNATIONAL STANDARD ISO 8873-1:2006(E)
Rigid cellular plastics — Spray-applied polyurethane foam for
thermal insulation —
Part 1:
Material specifications
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 responsibility of the user to establish appropriate safety and health practices and
to ensure compliance with any regulatory requirements.
1Scope
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 −60 C to +80 C.
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.
