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. 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
any patent rights identified during the development of the document will be in the Introduction and/or

This first edition of ISO 4586-4:2015 cancels and replaces (ISO 4586-1:2004), which has been
technically revised.
ISO 4586 consists of the following parts, under the general title Plastics — High-Pressure Decorative

INTERNATIONAL STANDARD ISO 4586-4:2015(E)
High-pressure decorative laminates (HPL, HPDL) — Sheets
based on thermosetting resins (Usually called Laminates) —
Part 4:
Classification and specifications for compact laminates of
thickness 2 mm and greater
1 Scope
This part of ISO 4586 specifies performance requirements for two types of Compact laminate (defined
in Clause 4) of thickness 2 mm or greater intended for interior use.
High-pressure decorative Compact laminates are characterized by their aesthetic qualities, strength,
durability and functional performance. Compact HPL sheets are available in a wide variety of colours,
patterns and surface finishes; they are extremely strong, and resistant to wear, impact, scratching,
moisture, heat and staining; and possess good hygienic and anti-static properties, being easy to clean
and maintain.
ISO 4586-2 specifies the methods of test relevant to this part of ISO 4586.
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,
Cigarette Burns - 36/37, 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, consult the documentation in specific sections of ISO 4586
for performance requirements. Each specific method has performance requirements particular to that
method for individual grades of high-pressure decorative laminate.

ISO 4586-4:2015(E)
3.1
High-Pressure Decorative Compact Laminate(s)
HPL
HPDL
sheet(s) consisting of layers of cellulosic fibrous material (normally paper) impregnated with
thermosetting resins and bonded together by the high pressure process described below
Note 1 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.
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
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.
4 Material types and classification system
4.1 General
Compact laminates are defined using a three letter classification system as shown in Table 1.
Table 1 — Compact laminate classification system
FIRST LETTER SECOND LETTER THIRD LETTER
S (STANDARD GRADE)
C (COMPACT GRADE) G (GENERAL PURPOSE)
or F (FLAME-RETARDANT GRADE)
4.2 Type CGS - Standard grade decorative Compact laminates. Specified as HPL/ISO 4586-4/CGS.
4.3 Type CGF - Decorative Compact laminates with improved fire retardance similar to type CGS
but also meeting special requirements of specified tests which may vary according to the application
(e.g. construction, marine, transport) and the country of use (see 6.3.2 and Annex B). Specified as
HPL/ISO 4586-4/CGF.
Other laminates having special characteristics are also available but these products are outside the
scope of this part of the standard.
5 Characteristics and applications
HPL Compact laminates have the following characteristics:
— Attractive aesthetic qualities
— High mechanical strength
— Durability (high resistance to impact, wear and scratching)
— Good dimensional stability
— High resistance to the effects of water, steam, heat and frost
— Non-corrosive
— Good colour fastness

ISO 4586-4:2015(E)
— Easy to clean and maintain (good anti-graffiti properties)
— Hygienic
— Good chemical resistance
— No dust attraction
— Ease of installation
— Good fire performance
Typical applications include wall cladding, partitions, doors, cubicles, lockers, laboratory bench tops,
and various self-supporting components in construction, marine and transport industries.
When Compact laminates are self-supporting they are ready for installation and only require cutting to
size, drilling, etc. to suit the application.
6 Requirements
6.1 Compliance
Compact laminate types CGS and CGF shall meet all appropriate requirements specified in 6.2, 6.3, and
6.4. This applies to both full-size sheets and cut-to-size panels.
6.2 Inspection requirements
6.2.1 General
Inspection shall be carried out in accordance with ISO 4586-2, Test Method 4 at a distance of 1,5 m.
6.2.2 Colour and pattern
When inspected in daylight or D65 standard illuminate and again under tungsten illuminate F, there
shall be no significant difference between the corresponding colour reference sample held by the
supplier and the specimen under test.
NOTE Where colour and surface finish are critical, it is recommended that sheets be checked for colour and
surface-finish compatibility before fabrication or installation.
6.2.3 Surface finish
When inspected at different viewing angles, there shall be no significant difference between the
cor
