Overview
ISO 4586-1:2018 is the introductory part of the ISO 4586 series for high-pressure decorative laminates (HPL, HPDL) - sheets made from layers of cellulosic fibres (typically paper) impregnated with thermosetting resins. This part provides general information, definitions and guidance for selecting and applying the test methods and specifications given in ISO 4586‑2 to ISO 4586‑8. It also harmonizes where possible with EN 438‑1 and includes hygienic, health and safety guidance for interior use.
Key topics and requirements
- Scope and definitions: Precise terms (e.g., HPL/HPDL, surface layer, core layer, high‑pressure process). The high‑pressure process is defined as simultaneous heat (≥120 °C) and pressure (≥5 MPa) producing a dense, cured laminate (density ≥1.35 g/cm3).
- Series structure: Part 1 is an overview; Parts 2–8 cover test methods and product specifications for different laminate types (thin, compact, flooring, exterior, design, alternative core).
- Test method guidance: ISO 4586‑2 describes specific test methods to determine performance for internal and external applications (construction, transport, furniture, flooring). Not all tests apply to every laminate type (e.g., Test 12 - resistance to abrasion applies to flooring grades; Test 11 - resistance to surface wear applies to non‑flooring HPL).
- Classification system: Standardized product codes (H, V, C, E, AC, A, M, W, B, R, T) and sub‑classifications (D, G, S, F, P) to denote horizontal/vertical/compact/exterior grades, abrasion classes, pearlescent/metal/wood veneer cores, flame‑retardant or postforming grades, etc.
- Hygiene and safety (Annex A): Cleanability, recommended disinfectants (e.g., 70% ethanol), resistance to microbial growth (ISO 846), food contact migration test results typically observed (overall migration
