BS ISO 4586-6:2018 pdf download – High-pressure decorative laminates (HPL, HPDL) – Sheets based on thermosetting resins (usually called laminates) Part 6: Classification and specifications for exterior-grade compact laminates of thickness 2 mm and greater This document applies to exterior-grade compact laminates of thickness 2 mm 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 conditions. ISO 4586-2 specifies the methods of test relevant to this document. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

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. Note 3 to entry: The back of the sheet(s) may be made suitable for adhesive bonding to a substrate. 3.2 high-pressure process simultaneous application of heat (temperature ≥ 120 °C) and high specific pressure (≥ 5 MPa), to provide flowing and subsequent curing of the thermosetting resins to obtain...
