EN 438-6:2005 (E) 4 1 Scope This Part of EN 438 applies to Exterior-grade Compact laminates of thi

25、ckness 2mm and greater. 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 cond

26、itions. Laminates complying with this Part of EN 438 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 col

27、ours, 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 require cutting to size, drilling, etc. to suit the application. EN 438-2 specifies the methods of test relevant to this

28、part of EN 438. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 438-2,

31、his document, the following term and definition applies: 3.1 high-pressure decorative exterior-grade compact laminate(s) (HPL) sheet(s) consisting of layers of cellulosic fibrous material (e.g. paper) impregnated with thermosetting resins and bonded together by the high pressure process described be

32、low. The surface layer(s) on one or both sides, having decorative colours or designs, are impregnated with suitable thermosetting resins (aminoplastic based resins or others). A suitable outer layer or coating may be added to enhance weather and light protecting properties. The core layers are impre

33、gnated with phenolic based resins, and may be combined with other fibres and/or fillers during the manufacturing process The high pressure process is defined as the simultaneous application of heat (temperature 120 C) and high specific pressure ( 5 MPa), to provide flowing and subsequent curing of t

34、he thermosetting resins to obtain a homogeneous non-porous material with increased density ( 1,35 g/cm), and with the required surface finish.

35、5 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 system FIRST LETTER SECOND LETTER THIRD LETTER G (MODERATE USE) or D (SEVERE USE) S (STANDARD GRADE) or F (FLAME-RETARDANT G

36、RADE) E (EXTERIOR GRADE) For example an Exterior-grade flame-retardant HPL for severe outdoor conditions is specified as HPL/prEN 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

37、 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 Requirements 5.1 Compliance Exterior-grade Compact laminate types EGS, EGF, EDS and EDF shall meet all appropriate requirem

38、ents specified in Clauses 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 accordance with EN 438-2, Test Method 4 at a distance of 1,5 m. 5.2.2 Colour and pattern When inspected in daylight or

39、 D65 standard illuminant and again under tungsten illuminant F, there shall be no significant difference between the corresponding colour reference sample held by the supplier and the specimen under test. NOTE Where colour and surface finish are critical, it is recommended that sheets be checked for

40、 colour and surface finish compatibility before fabrication or installation. 5.2.3 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. NOTE Wher

41、e colour and surface finish are critical, it is recommended that sheets be checked for colour and surface finish compatibility before fabrication or installation.

EN 438-6:2005 (E) 6 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 sheet. Cut-to-size panels and certain applications involving f

43、ull-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 percentage of sheets in a batch (the level to be agreed with the custo

44、mer) 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: Dirt, spots and similar surface defects The admiss

45、ible size of such defects is based on a maximum contamination area equivalent to 2,0 mm2/m2 of 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. Fibres,

46、 hairs and scratches The admissible size of defects is based on a maximum contamination length equivalent to 20 mm/m2 of 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 amou

47、nt of smaller defects. 5.2.4.3 Edge quality Edge chipping up to 3 mm on each side is permissible. 5.3 Dimensional tolerance requirements Dimensional tolerance requirements are specified in Table 2.
