Introduction
High‐pressure decorative laminates are characterized by their qualities, durability, and functional
performance. High‐pressure laminates sheet are available in a wide variety of colours, patterns, and
surface finishes. They are resistant to wear, scratching, impact, moisture, heat, and staining; and
possess good hygienic and anti‐static properties, being easy to clean and maintain.
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 438‐8 whenever possible.

HPDL
sheet consisting of layers of cellulosic fibrous material (normally paper) impregnated with
thermosetting resins and bonded together by the high pressure process (3.2)
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 back of the sheet(s) is 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‐

porous material with increased density (≥ 1,35 g/cm), and with the required surface finish
3.3
pearlescent laminate
high-pressure decorative laminate (3.1), the surface material of which consists of a pearlescent effect
decorative paper, which is impregnated with melamine resin
Note 1 to entry: To achieve the optimum aesthetic effect from the pearlescent pigment a protective melamine
layer is not used.
Note 2 to entry: As a result, some surface properties are reduced (e.g. scratch, wear) therefore it is recommended
that these products are used for vertical applications.
3.4
metal laminate
high-pressure decorative laminate (3.1), the surface material of which consists of a thin layer of metal
EXAMPLE Aluminium, steel, or copper.
Note 1 to entry: The surface is often protected by a thin layer of lacquer or in the case of aluminium, the surface
may be anodized. The surface performance and appearance of these metal laminates is equivalent to that of a thin
metal sheet.
Note 2 to entry: As some surface properties are lower than that of melamine (e.g. scratch, wear), it is
recommended that these products are used for vertical applications.
3.5
wood veneer laminate
high-pressure decorative laminate (3.1), the surface material of which consists of a wood veneer, which
is covered by a protective melamine layer
Note 1 to entry: The surface appearance of these wood veneer laminates is similar to wood. Wood veneer
laminates are not normally available in postforming grade.
4 Material types
High pressure decorative design laminates are defined using a three letter classification system as
shown in Table 1.

Type S — Standard grade decorative laminates.
Type P — Postformable decorative laminates; similar to type S but can also be formed at elevated temperature.
Type F — Decorative laminates with improved fire retardance; similar to types S or P but also meeting special requirements
of specified fire tests which may vary according to the application (e.g. construction, marine, transport) and the country of
use (see 5.4.5).
In addition to the abbreviation “HPL” or “HPDL” and the number of this document, materials shall be specified by the
alphabetical classification system.
NOTE As an example, pearlescent standard grade thin high‐pressure decorative design laminate is designated as
HPL/ISO 4586‐8 ATS or HPDL/ISO 4586‐8 ATS.
5 Requirements
5.1 Compliance
High‐pressure decorative design laminates classified in Table 1 shall comply with all the 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, pattern and surface finish
When inspected in daylight or D65 standard illuminant, as specified in ISO 11664‐2, and under
tungsten‐filament lighting illuminant F as specified in ISO 11664‐2, a slight difference between the
corresponding colour reference sample held by the supplier and the specimen under test is acceptable.
As colour and surface finish are critical, it is recommended that the sheets are checked for colour and
surface finish compatibility without protective film before fabrication or installation.
Some of these products are directional in surface finish or colour and they shall be installed in the
correct orientation.
5.2.3 Metal
When inspected in daylight or D65 standard illuminant and under tungsten‐filament lighting
illuminant F a slight difference between the corresponding colour reference sample held by the supplier
and the specimen under test is acceptable.
As colour and surface finish are critical, it is recommended that the sheets are checked for colour and
surface finish compatibility without protective film before fabrication or installation.
Some of these products are directional in surface finish or colour and they shall be installed in the
correct orientation. Small indentations in the surface are unavoidable.
5.2.4 Wood veneer
Due to the fact that wood is a natural product, each veneer may be considered as unique. Slight colour
and structure differences are considered normal. Singularities such as knots and resin inclusions are

not considered as defects, but as a part of the décor. There are differences in light fastness performance
depending on the wood species and the source of the wood.
5.2.5 Reverse side
The reverse side of single‐sided sheets shall be suitable for adhesive bonding (e.g. sanded). In the case
of sanded backs, slight chatter marks shall be permitted.
5.2.6 Visual inspection
5.2.6.1 General
The following inspection requirements are intended as a general guide, indicating the minimum
acceptable quality for laminates. Cut‐to‐size panels and certain applications involving full‐size sheets
may call for special quality requirements which can be negotiated between the supplier and purchaser,
in such cases the following requirements may be used as a basis for agreement. Only a small percentage
of sheets in a batch (the level to be agreed upon between the supplier and the customer) shall contain
defects of the minimum acceptable level.
5.2.6.2 Surface quality
The following defects are permissible.
— Dirt, spots dents, and similar surface defects.
The admissible size of such defects is based on a maximum contamination area equivalent to
2 2
1,0 mm/m of laminate and is proportional to the sheet size under inspection.
The total admissible area of contamination may be concentrated in one spot or dispersed over an
unlimited amount of smaller defects.
— Fibres, hairs, and scratches.
The admissible size of such defects is based on a maximum contamination area equivalent to
2 2
10 mm/m of laminate and is proportional to the sheet size under inspection.
The total admissible area of contamination may be concentrated in one spot or dispersed over an
unlimited amount of smaller defects.
5.2.6.3 Edge quality
Visual defects (e.g. moisture marks, lack of gloss, corner damage) can be present on all four edges of the
laminate, providing the defect‐free length and width are at least the nominal size minus 20 mm.
5.3 Dimensional tolerance requirements
5.3.1 Dimensional tolerance requirements for pearlescent laminates
Dimensional tolerance requirements for pearlescent laminates are specified in Tables 2 and 3.

Introduction
High-pressure decorative laminates are characterized by their qualities, durability, and functional
performance. High-pressure laminates sheet are available in a wide variety of colours, patterns, and
surface finishes. They are resistant to wear, scratching, impact, moisture, heat, and staining; and
possess good hygienic and anti-static properties, being easy to clean and maintain.
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 438-8 whenever possible.

ISO 4586-7:2018(E)
3.1
high-pressure decorative laminate
HPL
HPDL
sheet consisting of layers of cellulosic fibrous material (normally paper) impregnated with
thermosetting resins and bonded together by the high pressure process (3.2)
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 back of the sheet(s) is 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
pearlescent laminate
high-pressure decorative laminate (3.1), the surface material of which consists of a pearlescent effect
decorative paper, which is impregnated with melamine resin
Note 1 to entry: To achieve the optimum aesthetic effect from the pearlescent pigment a protective melamine
layer is not used.
Note 2 to entry: As a result, some surface properties are reduced (e.g. scratch, wear) therefore it is recommended
that these products are used for vertical applications.
3.4
metal laminate
high-pressure decorative laminate (3.1), the surface material of which consists of a thin layer of metal
EXAMPLE Aluminium, steel, or copper.
Note 1 to entry: The surface is often protected by a thin layer of lacquer or in the case of aluminium, the surface
may be anodized. The surface performance and appearance of these metal laminates is equivalent to that of a
thin metal sheet.
Note 2 to entry: As some surface properties are lower than that of melamine (e.g. scratch, wear), it is recommended
that these products are used for vertical applications.
3.5
wood veneer laminate
high-pressure decorative laminate (3.1), the surface material of which consists of a wood veneer, which is
covered by a protective melamine layer
Note 1 to entry: The surface appearance of these wood veneer laminates is similar to wood. Wood veneer
laminates are not normally available in postforming grade.
4 Material types
High pressure decorative design laminates are defined using a three letter classification system as
shown in Table 1.
2 © ISO 2018 – All rights reserved
---------------------- Page: 7 ----------------------
ISO 4586-7:2018(E)
Table 1 — Numerical classification
First letter Second letter Third letter
A (Pearlescent laminate) C (Compact) S (Standard grade)
M (Metal laminate) T (Thin laminate, < 2 mm) or P (Postformable grade)
W (Wood laminate) or F (Flame-retardant grade)
Type S — Standard grade decorative laminates.
Type P — Postformable decorative laminates; similar to type S but can also be formed at elevated temperature.
Type F — Decorative laminates with improved fire retardance; similar to types S or P but also meeting special requirements
of specified fire tests which may vary according to the application (e.g. construction, marine, transport) and the country of
use (see 5.4.5).
In addition to the abbreviation “HPL” or “HPDL” and the number of this document, materials shall be specified by the
alphabetical classification system.
NOTE As an example, pearlescent standard grade thin high-pressure decorative design laminate is designated as HPL/
ISO 4586-8 ATS or HPDL/ISO 4586-8 ATS.
5 Requirements
5.1 Compliance
High-pressure decorative design laminates classified in Table 1 shall comply with all the 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, pattern and surface finish
When inspected in daylight or D65 standard illuminant, as specified in ISO 11664-2, and under
tungsten-filament lighting illuminant F as specified in ISO 11664-2, a slight difference between the
corresponding colour reference sample held by the supplier and the specimen under test is acceptable.
As colour and surface finish are critical, it is recommended that the sheets are checked for colour and
surface finish compatibility without protective film before fabrication or installation.
Some of these products are directional in surface finish or colour and they shall be installed in the
correct orientation.
5.2.3 Metal
When inspected in daylight or D65 standard illuminant and under tungsten-filament lighting
illuminant F a slight difference between the corresponding colour reference sample held by the supplier
and the specimen under test is acceptable.
As colour and surface finish are critical, it is recommended that the sheets are checked for colour and
surface finish compatibility without protective film before fabrication or installation.
Some of these products are directional in surface finish or colour and they shall be installed in the
correct orientation. Small indentations in the surface are unavoidable.

ISO 4586-7:2018(E)
5.2.4 Wood veneer
Due to the fact that wood is a natural product, each veneer may be considered as unique. Slight colour
and structure differences are considered normal. Singularities such as knots and resin inclusions are
not considered as defects, but as a part of the décor. There are differences in light fastness performance
depending on the wood species and the source of the wood.
5.2.5 Reverse side
The reverse side of single-sided sheets shall be suitable for adhesive bonding (e.g. sanded). In the case
of sanded backs, slight chatter marks shall be permitted.
5.2.6 Visual inspection
5.2.6.1 General
The following inspection requirements are intended as a general guide, indicating the minimum
acceptable quality for laminates. Cut-to-size panels and certain applications involving full-size sheets
may call for special quality requirements which can be negotiated between the supplier and purchaser,
in such cases the following requirements may be used as a basis for agreement. Only a small percentage
of sheets in a batch (the level to be agreed upon between the supplier and the customer) shall contain
defects of the minimum acceptable level.
5.2.6.2 Surface quality
The following defects are permissible.
— Dirt, spots dents, and similar surface defects.
The admissible size of such defects is based on a maximum contamination area equivalent to
2 2
1,0 mm /m of laminate and is proportional to the sheet size under inspection.
The total admissible area of contamination may be concentrated in one spot or dispersed over an
unlimited amount of smaller defects.
— Fibres, hairs, and scratches.
The admissible size of such defects is based on a maximum contamination area equivalent to
2 2
10 mm /m of laminate and is proportional to the sheet size under inspection.
The total admissible area of contamination may be concentrated in one spot or dispersed over an
unlimited amount of smaller defects.
5.2.6.3 Edge quality
Visual defects (e.g. moisture marks, lack of gloss, corner damage) can be present on all four edges of the
laminate, providing the defect-free length and width are at least the nominal size minus 20 mm.
5.3 Dimensional tolerance requirements
5.3.1 Dimensional tolerance requirements for pearlescent laminates
Dimensional tolerance requirements for pearlescent laminates are specified in Tables 2 and 3.
