ISO (the International Organization for Standardization) is a worldwide federation of national

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).

Introduction

High‐pressure decorative compact laminates are characterized by their aesthetic qualities, strength,

durability, and functional performance. Compact high‐pressure decorative laminate 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.

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 438‐4 whenever possible.

3.1
high-pressure decorative compact 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 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‐

porous material with increased density (≥ 1,35 g/cm), and with the required surface finish

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

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 document.
5 Characteristics and applications
HPL compact laminates have the following characteristics:
— attractive aesthetic qualities;
— high mechanical strength;
© ISO 2016 – All rights reserved
---------------------- Page: 6 ----------------------
ISO 4586-4:2018(E) Deleted: /PRF
— 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;
— 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 4586‐2:2018, Clause 4 at a distance of 0,75 m to

1,5 m.
6.2.2 Colour and pattern

When inspected in daylight or D65 standard illuminate and again under tungsten illuminate 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.
6.2.3 Surface finish

When inspected at different viewing angles, there shall be no significant difference between t
