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

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

on the ISO list of patent declarations received (see www .iso .org/ patents).

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 — 36/37, and Blistering — 38/39. 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.

ISO/DIS 4586-4:2020(E)

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

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
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;
