BS ISO 4586-6:2018 pdf free.High-pressure decorative laminates (HPL, HPDL) – Sheets based on thermosetting resins
sheet consisting of layers of cellulosic fibrous material (normally paper) impregnated with thermosetting resins and bonded together by the high pressure process (3.2)
Note 1 to entry: This is a general definition of high-pressure decorative laminate(s). More specific product definitions can be found in ISO 4586-3 to ISO 4586-8.
Note 2 to entry: The surface layer(s) on one or both sides, having decorative colours or designs, are ty pically impregnated with melamine based resins. The core layers are typically impregnated with phenolic based resins.
Note 3 to entry: The back of the sheet(s) may be made suitable for adhesive bonding to a substrate.
simultaneous application of heat (temperature 2 120 °C) and high specific pressure (2 5 MPa), to provide flowing and subsequent curing of the thermosetting resins to obtain a homogeneous non-porous material with increased density (2 1,35 g/cm3), and with the required surface finish 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, and textiles, etc. which are not necessarily treated with thermosetting resin fibrous material (usually paper) impregnated with thermosetting resins (usually phenolic based resins) or other curable resins, possibly reinforced by metal layer(s) or metal mesh(es) and others which are not necessarily treated with thermosetting resin
For example an exterior-grade flame-retardant HPL for severe outdoor conditions is specified as HPL/ISO 4586-6/EDE
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 intended for severe outdoor conditions, for example applications involving long term exposure to strong sunlight and weather.
The requirements for reaction to fire are determined by the fire regulations of the country in which the material is to be used. The reaction-to-fire of construction products is classified in accordance with various test methods specific to individual nation where the material is installed. For applications other than construction, fire test methods and performance requirements may vary from one country to another, and at present it is not possible, with any test, to predict compliance with all national and other requirements. No fire performance test is therefore included in this specification, however Annex B gives examples of how high-pressure laminates relate to ASTM E84[4] and EN 13501-1[2] and some of the most common fire test scenarios.
