EN 438-9:2017 (E) 3 European foreword This document (EN 438-9:2017) has been prepared by Technical Committee CEN/TC 249 “Plastics”, the secretariat of which is held by NBN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2018, and conflicting national standards shall be withdrawn at the latest by June 2018. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 438-9:2010+A1:2013. The following technical changes have been made in comparison to EN 438-9:2010+A1:2013, in Table 6 and in Table 7: — test methods, have been updated; — the Resistance to surface wear, has been modified and the Laminate grades

corrected; — for the Resistance to immersion in boiling water, the Appearance has been improved for the Laminate grades; — the Tesile strength, has been deleted to be in line with EN 438-4:2016; — in Table 6, for the Resistance to crazing, the Appearance of the Laminate grade has been corrected. EN 438, High-pressure decorative laminates (HPL) — Sheets based on thermosetting resins (usually called laminates), consists of the following parts: — Part 1: Introduction and general information — Part 2: Determination of properties — Part 3: Classification and specifications for laminates less than 2 mm thick intended for bonding to supporting substrates — Part 4: Classification and specifications for compact laminates of thickness 2 mm and greater — Part 5: Classification and specifications for flooring grade laminates less than 2 mm thick intended for bonding to supporting substrates — Part 6: Classification and specifications for exterior-grade Compact laminates of thickness 2 mm and greater — Part 7: Compact laminate and HPL composite panels for internal and external wall and ceiling finishes — Part 8: Classification and specifications for design laminates — Part 9: Classification and specifications for alternative core laminates SIST EN 438-9:2018

EN 438-9:2017 (E) 5 1 Scope This European Standard specifies performance requirements for alternative core laminates intended for interior use, the core layer compositions of which are not covered by EN 438-3 [1], EN 438-4 [2], EN 438-5 [3], EN 438-6 [4] and EN 438-8 [5]. The core layer types (coloured core layer and metal reinforced core layer) are defined in this part of EN 438. EN 438-2 specifies the test methods relevant to this European Standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1.1 high-pressure decorative alternative core laminate(s) alternative core laminate(s) HPL sheet(s) consisting of decorative surface layer(s) and alternative core layers bonded together by an high pressure process Note 1 to entry: Typical values for the high pressure process are a temperature of

120 °C and a pressure of

5 MPa. 3.1.2 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) Note 1 to entry: The surface layers appear on one or both side(s) of the laminate(s). In case of one-sided laminates, the back of the sheet(s) can be made suitable for adhesive bonding to a substrate. SIST EN 438-9:2018

EN 438-9:2017 (E) 6 3.1.3 alternative core layer 3.1.3.1 coloured core layer coloured fibrous materials (usually paper) impregnated with aminoplastic thermosetting resins (usually melamine based resins) or fibrous materials (usually paper) impregnated with coloured aminoplastic thermosetting resins (usually melamine based resins) Note 1 to entry: A translucent laminate is achieved by using clear resins and bleached fibres. Note 2 to entry: The surface layer and the coloured core layers can have the same colour producing a uniformly coloured laminate or be different colours to achieve a succession of coloured layers. 3.1.3.2 metal reinforced core layer metal layer(s) or mesh(es) and cellulosic fibrous layers (usually paper) impregnated with phenolic thermosetting resins or aminoplastic thermosetting resins (usually melamine based resins) Note 1 to entry: The purpose of including the metal layers is to improve the mechanical, fire or permeability performances of the laminate. Additionally the metal layers can give aesthetic improvements to edge. 3.2

Symbols For the purposes of this document, the following symbol applies. t nominal thickness of the alternative core laminate 4 Material types and classification system Alternative core laminates are defined using a three-letter classification system as shown in Table 1. Table 1 — Alternative core laminate classification system First letter Second letter Third letter B

(Metal reinforced core layer laminate) C
(Compact) T
(Thin laminate < 2 mm) S
(Standard grade) or F

(Flame retardant grade) Type S – Standard grade high-pressure decorative alternative core laminates. Type F – High-pressure decorative alternative core laminates with improved fire retardance, similar to type S but also complying with special requirements of specified tests which may vary according to the application (e.g. construction, marine, transport) and the country of use (see 5.4.3). NOTE These types of laminate are normally not postformable. In addition to the abbreviation “HPL” and the number of this European Standard, materials are specified by the alphabetical classification system.

EN 438-9:2017 (E) 7 5 Requirements 5.1

Compliance Alternative core layer laminates classified in Table 1 shall comply with all appropriate requirements specified in 5.2, 5.3 and 5.4. This applies to both full-size sheets and cut-to-size panels. 5.2

Inspection requirements 5.2.1

General Inspection shall be carried out in accordance with EN 438-2:2016, Clause 4, at a distance between 750 mm and 1 500 mm. 5.2.2

Colour and pattern When inspected in daylight or D65 standard illuminant, as specified in EN ISO 11664-2, and also under tungsten-filament lightning illuminant A as specified in EN ISO 11664-2, a slight difference between the corresponding colour reference sample held by the supplier and the specimen under test is acceptable. When colour and surface finish are critical, it is recommended that sheets are checked for colour and surface-finish compatibility without protective film before fabrication or installation. 5.2.3

Surface finish When inspected at different viewing angles, there shall be no significant difference between the corresponding surface-finish reference sample held by the supplier and the specimen under test. When colour and surface finish are critical, it is recommended that sheets are checked for colour and surface-finish compatibility without protective film before fabrication or installation. 5.2.4

Reverse side The reverse side of single-sided sheets shall be suitable for ad
