29、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

30、 resins) BS EN 438-4:2016EN 438-4:2016 (E) 5 Note 1 to entry: 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) may be made suitable for adhesive bonding to a substrate. 3.1.3 core layer fibrous material (usually paper)

31、impregnated with thermosetting resins (usually phenolic based resins) 3.2 Symbols For the purposes of this document, the following symbol applies. t nominal thickness 4 Material types and classification system Compact laminates are defined using a three letter classification system as shown in Table

32、 1 Table 1 Compact laminate classification system First letter Second letter 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.

33、s with improved fire retardance are similar to type CGS but also meeting special 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 sp

34、ecial characteristics are also available but these products are outside the scope 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

35、, wear and scratching); Good dimensional stability; High resistance to the effects of water, steam, heat and frost; Non-corrosive; Good colour fastness; Easy to clean and maintain (good anti-graffiti properties); Hygienic; Good chemical resistance; BS EN 438-4:2016EN 438-4:2016 (E) 6 No dust attract

36、ion; Ease of installation; Good fire performance. Typical applications include 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 read

37、y for installation and only require cutting to size, drilling, etc. to suit 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 Insp

38、ection requirements 6.2.1 General Inspection shall be carried out in accordance 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 light

39、ning 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. NOTE Where colour and surface finish are critical, it is advised that sheets be checked for colour and surface-finis

40、h compatibility before fabrication or installation. 6.2.3 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. The maximum permitted deviations f

43、-4:2016 (E) 7 6.2.4 Visual inspection 6.2.4.1 General The following inspection requirements are intended as a general guide, indicating the minimum acceptable quality for each decorative face of a laminate supplied as a full-size sheet. Cut-to-size panels and certain applications involving full-size

44、 sheets may call for special quality requirements which can be negotiated between supplier and purchaser; in such cases the following requirements may be used as a basis for agreement. It should be noted that only a small percentage of sheets in a batch (the level to be agreed with the customer) sho

45、uld contain defects of the minimum acceptable level. It may be agreed between purchaser and supplier that the visual quality standard applies to one decorative face only. 6.2.4.2 Surface quality The following surface defects are permissible: a) dirt, spots and similar surface defects. The admissible

46、 size of such defects is based on a maximum contamination area equivalent to 1,0 mm2/m2of laminate and is proportional to the sheet size under inspection. The total admissible area of contamination may be concentrated in one spot or dispersed over an unlimited amount of smaller defects. b) fibres, h

47、airs and scratches. The admissible size of defects is based on a maximum contamination length equivalent to 10 mm/m2of laminate and is proportional to the sheet size under inspection. The total admissible length of contamination may be concentrated in one defect or dispersed over an unlimited amount

48、 of smaller defects. 6.2.4.3 Edge quality Edge chipping up to 3 mm on each side is permissible. 6.3 Dimensional tolerance requirements Dimensional tolerance requirements are specified in Table 2.
