DIN EN 438-6:2016-06 EN 438-6:2016 (E) 4 1 Scope This European Standard applies to Exterior-grade Compact laminates of thickness 2 mm and greater produced by using a high press
28、ure process. It specifies requirements for standard and flame-retardant laminates intended for use under outdoor weather conditions such as direct sunlight rain and frost. Two levels of performance are specified; one for moderate exterior conditions, and the other for severe exterior conditions. Lam
29、inates complying with this European Standard are referred to as Exterior-grade Compact laminates, and are characterized by their high tensile strength, high impact resistance, thermal shock resistance, and resistance to weather and corrosion. They are available in a variety of decorative colours, wi
30、th 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 require cutting to size, drilling, etc. to suit the application. EN 438-2 specifies the methods of test relevant to this part of

37、 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) impregnated with thermosetting resins (usually phenolic based resins) or
38、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 Exterior-grade Compact laminates are defined using the three letter classification system shown in Table 1. Table 1 Classification
39、 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-grade flame-retardant HPL for severe outdoor conditions is specified as HPL/EN 438-6/EDF. Laminate grades EGS and EGF are inte
40、nded for moderate outdoor conditions, for example applications involving medium term exposure to average levels of sunlight and weathering. Laminate grades EDS and EDF are intended for severe outdoor conditions, for example applications involving long term exposure to strong sunlight and weather. 5
41、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 both full-size sheets and cut-to-size panels. 5.2 Inspection requirements 5.2.1 General Inspection shall be carried out in ac
42、cordance with EN 438-2:2016, Clause 4 at a distance between 750 mm to 1500 mm. DIN EN 438-6:2016-06 EN 438-6:2016 (E) 6 5.2.2 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
43、 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 surface finish are critical, it is advised that sheets be checked for colour and surface-finish compatibility before fabri
44、cation 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 inspected at different viewing angles, there shall be no significant difference between the corresponding surface-fin
45、ish 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 maximum deviation 15 GU Semi Gloss surface 30 70 GU maximum deviation 10 GU Semi Matt surface 10 30 GU maximum deviati
46、on 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 between different lots of specimen. NOTE Where colour and surface finish are critical, it is advised that sheets be chec
47、ked 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 general guide, indicating the minimum acceptable quality for each decorative face of a laminate supplied as a full-size
48、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 cases the following requirements may be used as a basis for agreement. It should be noted that only a small percenta
49、ge 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 visual 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 bas
