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

35、f 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) DIN EN 438-4:2016-06 EN 438-4:2016 (E)5 Note 1 to entry: The surface lay

36、ers can appear on one or both side(s) of the laminate(s). In case of one-sided laminates, the back of the sheet(s) may be made suitable for adhesive bonding to a substrate. 3.1.3 core layer fibrous material (usually paper) impregnated with thermosetting resins (usually phenolic based resins) 3.2 Sym

38、Third letter C (compact grade) G (general purpose) S (standard grade) or F (flame-retardant grade) Type CGS Standard grade decorative Compact laminates are specified as HPL/EN 438-4/CGS. Type CGF Decorative Compact laminates with improved fire retardance are similar to type CGS but also meeting spec

39、ial requirements of specified tests which may vary according to the application (e.g. construction, marine, transport) and the country of use (see 6.4.2 and Annex A). Specified as HPL/EN 438-4/CGF. Other laminates having special characteristics are also available but these products are outside the s

40、cope of this part of the standard. 5 Characteristics and applications HPL Compact laminates have the following characteristics: Attractive aesthetic qualities; High mechanical strength; Durability (high resistance to impact, wear and scratching); Good dimensional stability; High resistance to the ef

41、fects of water, steam, heat and frost; Non-corrosive; Good colour fastness; Easy to clean and maintain (good anti-graffiti properties); Hygienic; Good chemical resistance; DIN EN 438-4:2016-06 EN 438-4:2016 (E) 6 No dust attraction; Ease of installation; Good fire performance. Typical applications i

42、nclude wall cladding, partitions, doors, cubicles, lockers, laboratory bench tops, and various self-supporting components in construction, marine and transport industries. When Compact laminates are self-supporting they are ready for installation and only require cutting to size, drilling, etc. to s

43、uit the application. 6 Requirements 6.1 Compliance Compact laminate types CGS and CGF shall meet all appropriate requirements specified in 6.2, 6.3, and 6.4. This applies to both full-size sheets and cut-to-size panels. 6.2 Inspection requirements 6.2.1 General Inspection shall be carried out in acc

44、ordance with EN 438-2:2016, Clause 4 at a distance between 750 mm to 1500 mm. 6.2.2 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 be

45、tween the corresponding colour reference sample held by the supplier and the specimen under test is acceptable. NOTE Where colour and surface finish are critical, it is advised that sheets be checked for colour and surface-finish compatibility before fabrication or installation. 6.2.3 Surface finish

46、 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. The maximum permitted deviations for the gloss value determined according to EN 13722 are Gloss surface 70

47、 GU maximum deviation 15 GU Semi Gloss surface 30 70 GU maximum deviation 10 GU Semi Matt surface 10 30 GU maximum deviation 5 GU Matt surface 10 GU maximum deviation 3 GU GU = gloss units The measurement shall be carried out with the same device as comparison between reference sample and specimen o

48、r between different lots of specimen. NOTE Where colour and surface finish are critical, it is advised that sheets be checked for colour and surface-finish compatibility before fabrication or installation.
