This European standard specifies test methods for determination of the suitability of two component epoxy and polyurethane adhesives for on-site repair of cracked timber structures. The standard specifies minimum requirements on bond strength and integrity. The standard provides minimum on-site repair provisions and specifies test and minimum strength requirements with drill cores from on-site repaired timber structures for verification of bond strength and integrity.

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.

This International Standard specifies the method for measuring relative wet grip braking performance index to a reference under loaded conditions for new tyres for use on passenger cars on a wet-paved surface.

The methods developed are meant to reduce variability. The use of a reference tyre is necessary to limit the variability of the testing procedures.

This International Standard applies to all passenger car tyres except for:

— Special tyres

— tyres fitted with additional devices to improve traction properties (e.g. studded tyres).

This International Standard specifies a test method to determine the degree and rate of aerobic biodegradation of plastic materials when settled on marine sandy sediment at the interface between seawater and the seafloor, by measuring the evolved carbon dioxide.

This test method is a simulation under laboratory conditions of the habitat found in different seawater/sediment-areas in the sea, e.g. in a benthic zone where sunlight reaches the ocean floor (photic zone) that, in marine science, is called sublittoral zone

The determination of biodegradation of plastic materials buried in marine sediment is outside the scope of this International Standard.

Measurement of aerobic biodegradation can also be obtained by monitoring the oxygen consumption, as described in ISO 18830.

The conditions described in this International Standard may not always correspond to the optimum conditions for the maximum degree of biodegradation to occur.
