The core layer types (coloured core layer and metal reinforced core layer) are
31、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.

35、he 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 e
36、ntry: 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) No
37、te 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. BS EN 4389:2017EN 438-9:2017 (E) 6 3.1.3 alternative core layer 3.1.3.1 coloured core layer coloured
38、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
39、 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)
40、 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 laminat

43、e) 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.
44、construction, marine, transport) and the country of use (see 5.4.3). NOTE These types of laminate are normally not postformable.
