33、ons, requirements and test methods 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. DIN EN 438-1:2016-06 EN 438-1:2016 (E) 5 3.1 high-pressure decorative laminate(s) HPL sheet(s) consisting of decorative surface layer(s) and core layers bonded tog
34、ether by a high pressure process Note 1 to entry: Typical values for the high pressure process are a temperature of 120 C and a pressure of 5 MPa. 3.2 surface layer upper decorative layer consisting in one or more sheets of fibrous material (usually paper) impregnated with aminoplastic thermosetting
35、 resins (usually melamine based resins) or other curable resins or other decorative design surfaces such as metal foils, wood-veneers and textiles, etc. which are not necessarily treated with thermosetting resin Note 1 to entry: The surface layers can appear on one or both side(s) of the laminate(s)
36、. In case of one-sided laminates, the back of the sheet(s) may be made suitable for adhesive bonding to a substrate. 3.3 core layer fibrous material (usually paper) impregnated with thermosetting resins (usually phenolic based resins) or other curable resins, eventually reinforced by metal layer(s)
37、or metal mesh(es) and others which are not necessarily treated with thermosetting resin 4 Guidance in the use of the standard 4.1 Description of parts EN 438-2 specifies the methods of test that shall be used to determine the performance of HPL products in their various internal and external applica
38、tion fields, e.g. construction, transport, furniture, flooring, etc. The test methods have been specifically developed for testing HPL. It should be noted that not all test methods apply to all types of HPL. For example Test 11, Resistance to Abrasion, applies only to flooring grade laminates; while
39、 Test 10, Resistance to Surface Wear, applies to all types of HPL except flooring grade laminates. It is therefore important to read the scope of the test method to determine whether it is applicable to a particular HPL product. EN 438-3, EN 438-4, EN 438-5, EN 438-6, EN 438-8 and EN 438-9 specify t
40、he performance requirements for different types of high-pressure decorative laminates. Each of these parts is independent of the others, and only requires reference to EN 438-2 for details of the appropriate test methods. EN 438-3 applies to laminates less than 2 mm thick intended for bonding to sup
41、porting substrates to produce HPL composite panels. Classification systems and performance requirements are specified for heavy duty, horizontal and vertical grades of laminate, in standard, postforming and flame-retardant qualities. EN 438-4 applies to Compact laminates of thickness 2 mm and greate
42、r, in standard and flame-retardant qualities, intended for interior applications. EN 438-5 applies to flooring grade laminates less than 2 mm thick intended for bonding to supporting substrates, to produce HPL flooring elements. As laminate floor coverings they meet the requirements of EN 13329. DIN
43、 EN 438-1:2016-06 EN 438-1:2016 (E) 6 EN 438-6 applies to Exterior-grade Compact laminates of thickness 2 mm and greater, and specifies requirements for standard and flame-retardant laminates for use in moderate and severe outdoor conditions. EN 438-7 is the harmonised standard covering the essentia
44、l requirements specified in Construction Products Regulation for Internal and External Wall and Ceiling Finishes. EN 438-8 applies to design laminates (pearlescent, wood veneer and metal surfaces).Classification system and performance requirements are specified for thin and compact laminates. EN 438
45、-9 applies to alternative core laminates (coloured and metal reinforced cores). Classification system and performance requirements are specified for thin and compact laminates. 4.2 Applications Table 1 below shows how the different parts of the standard relate to various fields of application. Table
46、 1 Applicable fields Application Part 3 Part 4 Part 5 Part 6 Part 8 Part 9 Construction (internal) Construction (external) Transport Furniture Flooring 5 Product classification systems EN 438-3, EN 438-4, EN 438-5, EN 438-6, EN 438-8 and EN 438-9 include product classification systems. While each of
47、 these systems is different, they contain some common elements as follows: Main classifications: H denotes Horizontal grade V denotes Vertical grade C denotes Compact laminate E denotes Exterior grade AC denotes Abrasion Class for flooring grade A denotes Pearlescent laminate M denotes Metal laminat
48、e W denotes Wood veneer laminate B denotes Coloured core laminate R denotes Metal reinforced core laminate T denotes Thin laminate 2 mm Sub-classifications: D denotes Heavy duty or severe use G denotes General purpose or moderate use S denotes Standard grade DIN EN 438-1:2016-06 EN 438-1:2016 (E) 7
49、F denotes Flame-retardant grade P denotes Postforming grade In Part 5, the classification system AC1 to AC6 has been adopted as these classes relate directly to the corresponding product abrasion classes in EN 13329.
