1 Scope
This document specifies characteristics for compact laminate panels and HPL composite panels both for
non-structural uses in interior or external wall and ceiling finish applications (including in suspended
ceiling).
This document deals with compact laminate panels of thickness 2 mm and greater.
The compact laminate panels are produced by using a high pressure process and the HPL composite
panels are produced bonding an HPL sheet to a substrate.
This document covers compact laminate panels with the following types of laminates:
— compact laminates, as defined in EN 438-4:2016;
— exterior-grade compact laminates, as defined in EN 438-6:2016;
— pearlescent compact laminates, metal compact laminates and wood veneer compact laminates, as
defined in EN 438-8:2018;
— coloured core layer compact laminates and metal reinforced core layer compact laminates, as defined
in EN 438-9:2017.
This document covers full size and cut-to-size compact laminate panels and HPL composite panels, e.g.
tiles and sidings.
This document specifies only compact laminate panels and HPL composite panels mechanically fixed
using e.g. screws or rivets.
Both the compact laminate panels and HPL composite panels may contain flame retardant to improve
their reaction to fire performance.
This document also specifies provisions for the assessment and verification of constancy of performance
(AVCP) of the characteristics and includes provisions for marking these panels.
This document does not cover:
a) HPL sheets less than 2 mm thick as defined in EN 438-3:2016, EN 438-8:2018 or EN 438-9:2017,
which are not glued on a substrate;
b) overlaid or veneered wood-based panels, where the overlay/veneer is not an HPL;
c) HPL composite panels intended for use as floor coverings;
d) panels used for fire protection of walls or ceilings;
e) performances of installed systems for walls and ceilings with compact or composite high pressure
laminate panels.

expressed as value in µg/m .
4.11 Thermal shock resistance
4.11.1 The thermal shock resistance for compact laminate panels only shall be done by determining the
change of appearance, the change of flexural strength and the change of flexural modulus of elasticity
according to 5.11.
4.11.2 The obtained results of these characteristics shall be evaluated according to the concerned criteria
in Table 5.
