22、e This European Standard applies to Exterior-grade Compact laminates of thickness 2 mm and greater produced by using a high pressure process. It specifies requirements for standard and flame-retardant laminates intended for use under outdoor weather conditions such as direct sunlight rain and frost.
23、 Two levels of performance are specified; one for moderate exterior conditions, and the other for severe exterior conditions. Laminates complying with this European Standard are referred to as Exterior-grade Compact laminates, and are characterized by their high tensile strength, high impact resista
24、nce, thermal shock resistance, and resistance to weather and corrosion. They are available in a variety of decorative colours, with high resistance to colour change and aging in outdoor applications. When they are self-supporting Exterior-grade Compact laminates are ready for installation, and only
25、require cutting to size, drilling, etc. to suit the application. EN 438-2 specifies the methods of test relevant to this part of EN 438. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

26、ed references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

29、oses 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 temperat
30、ure of 120 C and a pressure of 5 MPa. BS EN 438-6:2016EN 438-6:2016 (E) 5 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) or other curable resins, eventu
31、ally with a suitable outer layer or coating to enhance weather and light protecting properties 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.
32、3.1.3 core layer fibrous material (usually paper) impregnated with thermosetting resins (usually phenolic based resins) or other suitable curable resins 3.2 Symbols For the purposes of this document, the following symbol applies. t nominal thickness 4 Material types and classification system Exterio
33、r-grade Compact laminates are defined using the three letter classification system shown in Table 1. Table 1 Classification system First letter Second letter Third letter E (exterior grade) G (moderate use) or D (severe use) S (standard grade) or F (flame-retardant grade) For example an Exterior-gra
34、de flame-retardant HPL for severe outdoor conditions is specified as HPL/EN 438-6/EDF. Laminate grades EGS and EGF are intended for moderate outdoor conditions, for example applications involving medium term exposure to average levels of sunlight and weathering. Laminate grades EDS and EDF are inten
35、ded for severe outdoor conditions, for example applications involving long term exposure to strong sunlight and weather. 5 Requirements 5.1 Compliance Exterior-grade Compact laminate types EGS, EGF, EDS and EDF shall meet all appropriate requirements specified in 5.2, 5.3 and 5.4. This applies to bo
36、th 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 to 1500 mm. BS EN 438-6:2016EN 438-6:2016 (E) 6 5.2.2 Colour and pattern When inspected in daylight or D65 sta
37、ndard 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. NOTE 1 Where colour and surf
38、ace finish are critical, it is advised that sheets be checked for colour and surface-finish compatibility before fabrication or installation. NOTE 2 Some of these products are directional in surface finish or colour and it advised to install them in the correct orientation. 5.2.3 Surface finish When
39、 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 GU
40、maximum deviation 15 GUSemi 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 or bet
41、ween 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. 5.2.4 Visual inspection 5.2.4.1 General The following inspection requirements are intended as a gen
42、eral 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 sheets may call for special quality requirements which can be negotiated between supplier and purchaser; in such
43、 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) should contain defects of the minimum acceptable level. It may be agreed between purchaser and supplier that the vis
44、ual quality standard applies to one decorative face only. 5.2.4.2 Surface quality The following surface defects are permissible: a) dirt, spots and similar surface defects. The admissible size of such defects is based on a maximum contamination area equivalent to 2,0 mm2/m2of laminate and is proport
45、ional 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. BS EN 438-6:2016EN 438-6:2016 (E) 7 b) fibres, hairs and scratches. The admissible size of defects is based on a maximum cont
46、amination length equivalent to 20 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 of smaller defects. 5.2.4.3 Edge quality Edge chipping up to 3 mm on each si
47、de is permissible. 5.3 Dimensional tolerance requirements Dimensional tolerance requirements are specified in Table 2.
