1 Scope This Part of EN 438 specifies performance requirements for two types of Compact laminate (defined in Clause 4) of thickness 2 mm or greater intended for interior use. High-pressure decorative Compact laminates are characterised by their aesthetic qualities, strength, durability and functional performance. Compact HPL sheets are available in a wide variety of colours, patterns and surface finishes; they are extremely strong, and resistant to wear, impact, scratching, moisture, heat and staining; and possess good hygienic and anti-static properties, being easy to clean and maintain. EN 438-2 specifies the methods of test relevant to this part of EN 438. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

3 Term and definition For the purposes of this document, the following term and definition applies. 3.1 high-pressure decorative compact laminate(s) (HPL) sheet(s) consisting of layers of cellulosic fibrous material (normally paper) impregnated with thermosetting resins and bonded together by the high pressure process described below. The surface layer(s) on one or both sides, having decorative colours or designs, are impregnated with melamine based resins. The core layers are impregnated with phenolic based resins The high pressure process is defined as the 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 a homogeneous non-porous material with increased density (≥ 1,35 g/cm³), and with the required surface finish.

4.2 Type CGS Standard grade decorative Compact laminates. Specified as HPL/EN438-4/CGS. 4.3 Type CGF Decorative Compact laminates with improved fire retardance similar to type CGS but also meeting special requirements of specified tests which may vary according to the application (e.g. construction, marine, transport) and the country of use (see Clause 6.3.2 and Annex B). Specified as HPL/EN438-4/CGF. Other laminates having special characteristics are also available but these products are outside the scope of this part of the standard. 5 Characteristics and applications HPL Compact laminates have the following characteristics:  Attractive aesthetic qualities  High mechanical strength  Durability (high resistance to impact, wear and scratching)  Good dimensional stability  High resistance to the effects of water, steam, heat and frost  Non-corrosive  Good colour fastness  Easy to clean and maintain (good anti-graffiti properties)  Hygienic  Good chemical resistance  No dust attraction  Ease of installation  Good fire performance Typical applications include wall cladding, partitions, doors, cubicles, lockers, laboratory bench tops, and various self-supporting components in construction, marine and transport industries. When Compact laminates are self-supporting they are ready for installation and only require cutting to size, drilling, etc. to suit the application. SIST EN 438-4:2005
