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

High-pressure decorative laminates are characterized by their qualities, durability, and functional

performance. High-pressure laminate sheets 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 — 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 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 438-3 whenever possible.

In addition, Annex C provides information on electrostatic properties and is included as a convenient

reference to answer common questions.

High-pressure decorative laminates (HPL, HPDL) —
Sheets based on thermosetting resins (usually called
laminates) —
Part 3:
Classification and specifications for laminates less than
2 mm thick and intended for bonding to supporting
substrates
1 Scope

This document applies to high-pressure laminates (HPL) less than 2 mm thick normally intended for

bonding to supporting substrates to produce HPL composite panels and establishes a classification

system for high-pressure decorative laminates according to their performance and main recommended

fields of application, including materials with special characteristics, for example formability or defined

reaction to fire. This document also specifies requirements for the properties of the various types of

laminates covered by this classification system.

ISO 4586-2 specifies the methods of test relevant to this document. ISO 4586-4 through ISO 4586-8 are

reserved for other types of HPL materials.

ISO/DIS 4586-3:2020(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.
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
4.1 Type S — Standard grade decorative laminates.

4.2 Type P — Postformable decorative laminates, similar to type S but can also be formed at

elevated temperature.

4.3 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 6.4.3 and Annex B).
5 Requirements
5.1 General

Two different HPL classification systems are commonly used and both have been included in this

document as alternatives.
5.2 Numerical classification system

In this system the classification of a letter denoting material type (see Clause 4) followed by three

index numbers showing the levels of performance for wear resistance, impact resistance and scratch

resistance respectively.
Table 1 shows the performance levels corresponding to the index numbers.

Second index number — Impact resistance
Small diameter ball (N) 2 3 4
≥ 15 ≥ 20 ≥ 25
Third index number — Scratch resistance
Scratch resistance (Rating) 2 3 4
2 3 4

NOTE Index numbers 2, 3, and 4 are specified to maintain consistency with earlier editions of ISO 4586 parts. Index

number 1 represents a lower quality level that does not apply to HPL as defined by the scope of this document.

5.3 Alphabetical classification system
This system uses three letters to classify laminates as shown in Table 2.
Table 2 — Alphabetical classification
First letter Second letter Third letter
H (Horizontal grade) G (General purpose) S (Standard grade)
or V (Vertical grade) or D (Heavy duty) or P (Postformable grade)
or F (Flame-retardant grade)

Table 3 compares the alternative classification systems and shows how different HPL products relate to

some typical applications. The list of typical applications shown for each category is for guidance only

and is not intended to be comprehensive.

Combinations of wear, impact and scratch resistance index numbers other than those shown in Table 3 are possible and

can be specified using the numerical classification system. In such cases properties other than wear resistance, impact

resistance and scratch resistance shall meet the requirements specified for type VG in Table 5.
