High-pressure decorative laminates - Composite elements - Part 2 : Specifications for composite elements with wood-based substrates for interior use (ISO 13894-2:2005)

This part of ISO 13894 describes the general properties of composite elements surfaced, and possibly edged,
with high-pressure decorative laminate (HPDL) as defined in Clause 3. The composite elements specified in
this part of ISO 13894 consist of HPDL sheet material adhesively bonded to one or both sides of a woodbased
substrate, and are intended for normal interior use.
Requirements for special applications, e.g. where the product is subjected to extreme conditions of heat or
moisture, are not part of this part of ISO 13894, although Part 1 of this International Standard describes test
methods for additional properties which may be applicable to such applications (see ISO 13894-1:2000,
Subclause 3.1, Note 3).
Test methods and performance levels for special applications shall be agreed between customer and supplier.
Information concerning test methods for special applications is given in Annex A.

Stratifiés décoratifs haute pression - Éléments composites - Partie 2: Spécifications des éléments composites avec substrats à base de bois pour l'usage intérieur (ISO 13894-2:2005)

L'ISO 13894-2:2005 décrit les propriétés générales des éléments composites revêtus, et éventuellement plaqués avec chants, de stratifiés décoratifs haute pression (HPDL). Les éléments composites spécifiés se composent de feuilles de HPDL collées sur l'une ou les deux faces d'un substrat à base de bois et sont destinés à un usage intérieur normal.
Les exigences relatives à des applications particulières, par exemple lorsque le produit est soumis à des conditions extrêmes de chaleur ou d'humidité, ne sont pas spécifiées.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 13894-2 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 11, Products.
ISO 13894 consists of the following parts, under the general title High-pressure decorative laminates —
Composite elements:
