BS ISO 4586-5:2018 pdf free.High-pressure decorative laminates
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 typically impregnated with melamine based resins. The core layers are typically impregnated with phenolic based resins.
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 The classification system makes reference to ISO 10874 (level of use) in combination with the abrasion class (AC) given by a numerical rating of 1 to 6 defining the level of abrasion resistance, 6 being the highest and 1 the lowest performance.
Table 1 shows how the five abrasion classes of flooring grade laminate relate to level of use and some examples of typical applications.
Flooring grade laminates are specified according to abrasion class (e.g. HPL/ISO 4586- 5/AC1).
When inspected in daylight or D65 standard iluminate and again under tungsten iluminate A, there shall be no significant difference between the corresponding colour reference sample held by the supplier and the specimen under test.
Where colour and surface finish are critical, it is recommended that sheets be checked for colour and surface – finish compatibility before fabrication or installation.BS ISO 4586-5 pdf download.
