29、s apply. BS EN 438-1:2016EN 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 together by a high pressure process Note 1 to entry: Typical values for the high pressure process are a temperature of 120 C and a press

30、ure 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 resins (usually melamine based resins) or other curable resins or other decorative design surfaces such as metal foils, wood-veneers

31、 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). 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 f

32、ibrous material (usually paper) impregnated with thermosetting resins (usually phenolic based resins) or other curable resins, eventually reinforced by metal layer(s) or metal mesh(es) and others which are not necessarily treated with thermosetting resin 4 Guidance in the use of the standard 4.1 Des

33、cription 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 application fields, e.g. construction, transport, furniture, flooring, etc. The test methods have been specifically developed for testing HP

34、L. 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 Test 10, Resistance to Surface Wear, applies to all types of HPL except flooring grade laminates. It is therefore important to read

35、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 the performance requirements for different types of high-pressure decorative laminates. Each of these parts is independent of the othe

36、rs, 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 supporting substrates to produce HPL composite panels. Classification systems and performance requirements are specified for heavy duty,

37、 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 greater, in standard and flame-retardant qualities, intended for interior applications. EN 438-5 applies to flooring grade laminates less t

38、han 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. BS EN 438-1:2016EN 438-1:2016 (E) 6 EN 438-6 applies to Exterior-grade Compact laminates of thickness 2 mm and greater, and specifies re

39、quirements for standard and flame-retardant laminates for use in moderate and severe outdoor conditions. EN 438-7 is the harmonised standard covering the essential requirements specified in Construction Products Regulation for Internal and External Wall and Ceiling Finishes. EN 438-8 applies to desi

40、gn laminates (pearlescent, wood veneer and metal surfaces).Classification system and performance requirements are specified for thin and compact laminates. EN 438-9 applies to alternative core laminates (coloured and metal reinforced cores). Classification system and performance requirements are spe

41、cified 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.

42、ture 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 these systems is different, they contain some common elements as follows: Main classifications: H denotes Horizontal grade V denotes Vert

43、ical grade C denotes Compact laminate E denotes Exterior grade AC denotes Abrasion Class for flooring grade A denotes Pearlescent laminate M denotes Metal laminate W denotes Wood veneer laminate B denotes Coloured core laminate R denotes Metal reinforced core laminate T denotes Thin laminate 2 mm Su

44、b-classifications: D denotes Heavy duty or severe use G denotes General purpose or moderate use S denotes Standard grade BS EN 438-1:2016EN 438-1:2016 (E) 7 F denotes Flame-retardant grade P denotes Postforming grade In Part 5, the classification system AC1 to AC6 has been adopted as these classes r

45、elate directly to the corresponding product abrasion classes in EN 13329. BS EN 438-1:2016EN 438-1:2016 (E) 8 Annex A (informative) Addendum relating to hygienic, health and safety information for laminates intended for interior use A.1 Cleanability Because they are easy to clean and maintain, high-

46、pressure decorative laminates are suitable for use in hygienic applications such as hospitals, pharmacies, food processing areas, abattoirs, clean rooms, etc. For routine cleaning, wiping the surface with water and mild detergent is usually sufficient, but more severe methods such as hosing down wit

47、h hot water or steam cleaning can be used where required by the application. Solvents such as white spirit, acetone or cellulose thinners can also be used (e.g. for graffiti removal) as they will not affect the laminate. For the non melamine surface laminate cleaning, the manufacturer should be cont

48、acted. A.2 Hygiene When used in hospitals and surgeries, HPL melamine and other curable resin surfaces can be disinfected using any of the common disinfectants such as Ethanol 70 %, Formalin 1 % to 5 %, p-chlorine-m-cresol 0,3 %, Chloramine T 1 % to 5 %, Alkylbenzyldimethylammonium chloride 0,1 %. H

49、igh-pressure decorative laminates show a high resistance to fungal and bacterial growth, when tested in accordance with EN ISO 846. A.3 Contact with foodstuffs When determination of the overall and specific migration is carried out in accordance with the test method shown below, the following results are typical of those for HPL melamine and other suitable curable resin surfaces: Overall migration 10 mg/dm2Specific migration (formaldehyde) 2,5 mg/dm2Test met
