This document specifies a small-scale laboratory screening procedure for comparing the relative burning characteristics of horizontally oriented, small cellular plastic specimens having a density less than 250 kg⋅m−3 determined in accordance with ISO 845, when exposed to a small-flame ignition source.
NOTE Another International Standard which covers flexible cellular plastic and cellular rubber is ISO 3582[2].
This method of test is intended for quality assurance and limited product evaluation of cellular plastic materials under controlled laboratory conditions, and is not intended to assess the fire behaviour of, for example, building materials or furnishings under actual fire conditions.
The optional classification system described in Annex A is intended for the pre-selection of cellular plastic materials for products, including the determination of the ranges of material parameters that give the same classification (see 6.1).

ISO 4898:2018 specifies requirements and methods of testing for three categories of rigid cellular plastics thermal-insulation products for buildings. It covers rigid cellular plastics in the form of flat or profiled boards, with or without natural skins. They can also be faced or laminated with foil, plastic or metal films or sheets, mineral coatings, paper, cardboard or other materials.
ISO 4898:2018 is not applicable to materials used for the thermal insulation of pipes and vessels, for impact sound absorption or for acoustical insulation.
ISO 4898:2018 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 extruded polystyrene;
- PUR based on polyurethane.
The limiting quality values in this document 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 can be added to those specified in this document by agreement between purchaser and supplier.

This standard specifies, for flexible and rigid cellular polymeric materials, laboratory procedures which are intended to imitate the effects of naturally occurring reactions such as oxidation or hydrolysis by humidity. The physical properties of interest are measured before and after the application of the specified treatments. Test conditions are only given for open cellular latex, both open- and closed-cell polyurethane foams, and closed-cell polyolefin foams. Conditions for other materials will be added as required. The effect of the ageing procedures on any of the physical properties of the material can be examined, but those normally tested are either the elongation and tensile properties, or the compression or indentation hardness properties. These tests do not necessarily correlate either with service behaviour or with ageing by exposure to light. If desired, the ageing conditions contained in this document can be applied to composite structures containing any of the above types of cellular material. This can be helpful in the investigation of possible interactions between cellular materials and other substrates. Composite constructions can be in the form of complete finished products or representative small specimens cut there-from.

This International Standard specifies a general procedure for the determination of the volume
percentage of open and of closed cells of rigid cellular plastics, by measurement first of the geometrical
volume and then of the air-impenetrable volume of test specimens.
The procedure includes the correction of the apparent open-cell volume by taking into account the
surface cells opened by cutting during specimen preparation. Three alternative methods (method 1,
method 2a and method 2b), and corresponding apparatus, are specified for the measurement of the
impenetrable volume.

This part of ISO 8873 outlines requirements for the application of rigid cellular plastic spray polyurethane foam
for thermal insulation. The primary application of the material is for use as thermal insulation. Spray
polyurethane foam can also be used as the air barrier material which forms part of an air barrier assembly in
buildings. Under specific application conditions, the material can be used in vapour barrier applications in a
building assembly (details of the conditions can be obtained from the manufacturer). The application
requirements are for the installation of spray polyurethane foam whether applied on a building site or in a
prefabrication (manufacturing) facility.
This part of ISO 8873 can be used for non-building applications when agreed to by the supplier and the
purchaser.
The requirements include obligations for the manufacturer, the contractor and the installer. The requirements
include the selection of chemical components, application requirements, quality control and documentation of
the application, limitations for the application and requirements for safety and for disposal of associated waste
material and packaging.
Installation of spray polyurethane foam for thermal insulation, according to this part of ISO 8873 requires the
use of materials and/or equipment that could be hazardous (see Warning).
