High-pressure decorative laminates (HPL, HPDL) — Sheets based on thermosetting resins (usually called laminates) — Part 2: Determination of properties

This document specifies the methods of test for determination of the properties of high-pressure decorative laminates (HPL, HPDL) as defined in Clause 3. These methods are primarily intended for testing the sheets specified from ISO 4586‑3 to ISO 4586‑8. The precision of the test methods specified in Clauses 5, 6, 7, 8, 9, 10, 13, 14, 16, 19, 20, 21, 22, 24, 25, 26, 39, and 40 is not known because interlaboratory data are not available. When interlaboratory data are obtained, precision statements will be added to the test methods at the following revision. As all the other test methods have an end point determination based on subjective judgement, it is not meaningful to make a statement of precision in these cases.

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

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 438‐2 whenever possible.

1 Scope

This document specifies the methods of test for determination of the properties of high‐pressure

decorative laminates (HPL, HPDL) as defined in Clause 3. These methods are primarily intended

for testing the sheets specified from ISO 4586‐3 to ISO 4586‐8.

The precision of the test methods specified in Clauses 5, 6, 7, 8, 9, 10, 13, 14, 16, 19, 20, 21, 22,

24, 25, 26, 39, and 40 is not known because interlaboratory data are not available. When

interlaboratory data are obtained, precision statements will be added to the test methods at the

following revision. As all the other test methods have an end point determination based on

subjective judgement, it is not meaningful to make a statement of precision in these cases.

laminate shall be pre‐conditioned in accordance with the manufacturer’s recommendations until

equilibrium is reached.
10.4 Procedure

Place the laminate concave side up without restraint on a flat horizontal surface.

Place the bow gauge (see 10.2.1) so that the three feet (two fixed and one movable) are lightly

touching the surface of the laminate in the area of greatest deformation, and measure the

flatness deviation (shown on the dial gauge) to the nearest 0,1 mm.
10.5 Expression of results
The maximum flatness deviation measured using the bow gauge shall be recorded.
10.6 Test report

The test report shall include the following information: Deleted: Dimensions in millimetres¶

a) a reference to this document, i.e. ISO 4586‐2;
b) name, type and nominal thickness of the product;
c) maximum flatness deviation;
d) any deviation from the specified test method;
e) date of the test.
11 Resistance to surface wear
11.1 Principle

The test measures the ability of the decorative surface of the laminate under test to resist

abrasive wear through to the sub‐layer. Abrasion is achieved by rotating a specimen in contact

with a pair of loaded cylindrical wheels covered with abrasive paper. The wheels are positioned

so that their cylindrical faces are equidistant from the specimen's axis of rotation but not

tangential to it. As they are turned by the rotating specimen they abrade an annular track on the

specimen's surface. The numbers of revolutions of the specimen required to cause defined

degrees of abrasion are used as measures of resistance to surface wear. This test is not

applicable to flooring grade laminates.
11.2 Materials

11.2.1 Calibration plates of rolled zinc sheet, (Taber S‐34 or equivalent), having a thickness

of (0,8 ± 0,1) mm and a Brinell hardness of (48 ± 2) when tested in accordance with ISO 6506‐1,

except that the ball diameter shall be 5 mm and the load 360 N.
