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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of

Introduction
Exterior‐grade compact laminates are characterized by their high tensile strength, high impact
resistance, thermal shock resistance, and resistance to weather and corrosion. They are available in a
variety of decorative colours, with high resistance to colour change and aging in outdoor applications.
When they are self‐supporting exterior‐grade compact laminates are ready for installation, and only
require cutting to size, drilling, etc. to suit the application.
In an effort to harmonize ISO 4586 with other high‐pressure decorative laminate standards, multiple
methods may be published that demonstrate similar properties. In these instances, the same test
method title is given and is annotated as either “Method A” or “Method B”. This is the case in the
following tests: Edge squareness — 8/9, Dry heat — 17/18 Dimensional stability at elevated
temperatures — 19/20, Dimensional stability at ambient temperature — 21/22, Staining — 30/31,
Lightfastness — 32/33, Formability — 38/39, and Blistering — 40/41. In these instances, either
method may be utilized in testing. Compliance to both methods is not required. While these tests are
similar they are by no means identical and results of one method do not necessarily correspond to the
results of the accompanying test. In these situations, it is intended that the documentation in specific
parts of ISO 4586 for performance requirements be consulted. Each specific method has performance
requirements particular to that method for individual grades of high‐pressure decorative laminate.
This document has been harmonized with EN 438‐6 whenever possible.

INTERNATIONAL STANDARD ISO 4586‐6:2018(E)

High-pressure decorative laminates (HPL, HPDL) — Sheets
based on thermosetting resins (usually called laminates) —
Part 6: Classification and specifications for exterior-grade
compact laminates of thickness 2 mm and greater
1 Scope
This document applies to exterior‐grade compact laminates of thickness 2 mm and greater. It specifies
requirements for standard and flame‐retardant laminates intended for use under outdoor weather
conditions such as direct sunlight, rain, and frost. Two levels of performance are specified; one for
moderate exterior conditions, and the other for severe exterior conditions.
ISO 4586‐2 specifies the methods of test relevant to this document.
2 Normative references

constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.

ISO 4586-6:2018(E)
Note 1 to entry: This is a general definition of high‐pressure decorative laminate(s). More specific product
definitions can be found in ISO 4586‐3 to ISO 4586‐8.
Note 2 to entry: The surface layer(s) on one or both sides, having decorative colours or designs, are typically
impregnated with melamine based resins. The core layers are typically impregnated with phenolic based resins.
Note 3 to entry: The back of the sheet(s) may be made suitable for adhesive bonding to a substrate.
3.2
high-pressure process
simultaneous application of heat (temperature ≥ 120 °C) and high specific pressure (≥ 5 MPa), to
provide flowing and subsequent curing of the thermosetting resins to obtain a homogeneous non‐
3
porous material with increased density (≥ 1,35 g/cm), and with the required surface finish
3.3
surface layer
upper decorative layer consisting in one or more sheets of fibrous material (usually paper)
impregnated with aminoplastic thermosetting resins (usually melamine based resins) or other curable
resins or other decorative design surfaces such as metal foils, wood‐veneers, and textiles, etc. which are
not necessarily treated with thermosetting resin
3.4
core layer
fibrous material (usually paper) impregnated with thermosetting resins (usually phenolic based resins)
or other curable resins, possibly reinforced by metal layer(s) or metal mesh(es) and others which are
not necessarily treated with thermosetting resin
4 Material types and classification system
Exterior‐grade compact laminates are defined using the three letter classification system shown in
Table 1.
Table 1 — Classification system
First letter Second letter Third letter
E (Exterior grade) G (Moderate use) S (Standard grade)
or D (Severe use) or F (Flame‐retardant grade)
For example an exterior‐grade flame‐retardant HPL for severe outdoor conditions is specified as
HPL/ISO 4586‐6/EDF.
Laminate grades EGS and EGF are intended for moderate outdoor conditions, for example applications
involving medium term exposure to average levels of sunlight and weathering.
Laminate grades EDS and EDF are intended for severe outdoor conditions, for example applications
involving long term exposure to strong sunlight and weather.
5 Requirements
5.1 Compliance
Exterior‐grade compact laminate types EGS, EGF, EDS and EDF shall meet all appropriate requirements
specified in 5.2, 5.3 and 5.4. This applies to both full‐size sheets and cut‐to‐size panels.

5.2 Inspection requirements
5.2.1 General
Inspection shall be carried out in accordance with ISO 4586‐2:2018, Clause 4 at a distance of 0,75 m to
1,5 m.
5.2.2 Colour and pattern
When inspected in daylight or D65 standard illuminant and again under tungsten illuminant A, there
shall be no significant difference between the corresponding colour reference sample held by the
supplier and the specimen under test.
Where colour and surface finish are critical, it is recommended that sheets be checked for colour and
surface finish compatibility before fabrication or installation.
