CEN/TC 112/WG 5 - Regulated dangerous substances

ISO 12460-4:2016 specifies a desiccator method for the determination of the quantity of formaldehyde emitted from particleboard, fibreboard, plywood, oriented strand board (OSB) and wooden laminated flooring.

ISO 12460-5:2015 specifies an extraction method known as the "perforator method". It is used for the determination of the formaldehyde content of unlaminated and uncoated wood-based panels.

This European Standard specifies a chamber method with three options of test chambers for the determination of the formaldehyde emission from wood-based panels in terms of the steady-state concentration in a climate chamber under defined conditions, which relate to typical conditions in real-life. This chamber method can also be applied to the estimation of formaldehyde concentrations under various conditions in practice, by the use of mathematical models.

This European Standard specifies a method, known as the flask method, for determination of formaldehyde release from uncoated wood-based panels.

This document specifies a procedure for a chamber test with different options of chamber sizes to measure the formaldehyde concentrations in air from wood products under defined test conditions of temperature, relative humidity, loading and air exchange rate.
Results obtained from this small-scale chamber test method can be used for quality control (factory production control – ‘FPC’) based on correlation established by reference chamber test methods according to ISO, EN or ASTM standards. The establishment of a correlation is described in Annex D.

This document specifies the determination of free melamine in coated and uncoated wood-based-panels.
NOTE 1   It is also applicable to other wood-based products, to other solid products e.g. impregnates or decorative paper and to liquid products (e.g. adhesives).
The determination of melamine is performed by extraction in dimethyl sulfoxide (DMSO) and subsequent high-performance chromatography (HPLC) analysis and ultraviolet (UV) detection.
NOTE 2   For determination of melamine in foodstuff EN 16858 is applicable. For determination of melamine in animal feeding stuffs EN 17212 is applicable. For determination of melamine in textiles EN ISO 1833 26 is applicable.

This document specifies a procedure for determination of accelerated formaldehyde release from uncoated and coated wood-based panels using the gas analysis method. The procedure is also suitable for the testing of other materials (e.g. edge bands, floor coverings, foams, foils, laminated wood products, veneered wood products, coated wood products).

This document describes an extraction method called the perforator method, to determine the formaldehyde content of unlaminated and uncoated wood-based panels.

This document describes a procedure for determination of formaldehyde release from coated and uncoated wood-based panels under defined conditions.

The procedure is also suitable for the testing of other materials (e.g. edge bands, floor coverings, foams, foils, laminated wood products, veneered wood products, coated wood products).

ISO 12460-3:2015 specifies a procedure for determination of accelerated formaldehyde release from uncoated and coated wood-based panels using the gas analysis method. The procedure is also suitable for the testing of other materials (e.g. edge bands, floor coverings, foams, foils, laminated wood products, veneered wood products, coated wood products).

This European standard describes a procedure for determination of formaldehyde release from coated and uncoated wood-based panels under defined conditions.

This European standard specifies a chamber method with three options of test chambers for the determination of the formaldehyde emission from wood-based panels in terms of the steady-state concentration in a climate chamber under defined conditions, relating to average conditions in real-life. This chamber method can also be applied to the estimation of formaldehyde concentrations under various conditions in practice, by the use of mathematical models.
