3.2
high-pressure decorative alternative core laminate(s) alternative core laminate(s)
HPL sheet(s) consisting of decorative surface layers and alternative core layers bonded together by a high pressure process
NOTE 1 For alternative core layers, see 3.3. NOTE 2 The surface layer(s) on one or both face(s), having decorative colours or designs, impregnated with melamine based resins are supported by a core. The surface layers can appear on one or both side(s) of the laminate(s). In case of one-sided laminates the back of the sheet(s) is made suitable for adhesive bonding to a substrate. SIST EN 438-9:2010

3.3.1 coloured core laminate high-pressure decorative alternative core laminate, the core of which consists of cellulosic fibrous layers (normally paper) impregnated with thermosetting resins typically aminoplastic thermosetting resins NOTE 1 To achieve a coloured laminate, either the cellulosic fibres or the resins can be coloured. A translucent laminate can be achieved by using clear resins and bleached fibres. NOTE 2 The surface and the core layers can have the same colour producing a uniformly coloured laminate or be different colours to achieve a succession of coloured layers. 3.3.2 metal reinforced core laminate high-pressure decorative alternative core laminate, the core of which consists of metal layer(s) or mesh(es) and cellulosic fibrous layers (normally paper) impregnated with phenolic or aminoplastic thermosetting resins. NOTE 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. 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
(Coloured core laminate) H (Metal reinforced core 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.
EXAMPLE "Coloured core Standard Grade Thin high-pressure decorative laminate" is designated as
HPL/EN 438-9 BTS. 5 Requirements 5.1 Compliance Alternative core 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.
5.2.2 Colour and pattern When inspected in daylight or D65 standard illuminant, as specified in ISO 11664-2:2007, and also under tungsten-filament lightning illuminant A as specified in ISO 11664-2:2007, 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 adhesive bonding (e.g. sanded). In the case of sanded backs, slight chatter marks shall be permitted.
5.2.5 Visual inspection 5.2.5.1 General The following inspection requirements are intended as a general guide, indicating the minimum acceptable quality for laminates. Cut-to-size panels and certain applications involving full-size sheets may call for special quality requirements which can be negotiated between supplier and purchaser; in such cases the following requirements may be used
