Описание (английский):

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).

Overview

EN ISO 12460-3:2023 - Wood-based panels - Determination of formaldehyde release - Part 3: Gas analysis method (ISO 12460-3:2023) specifies a laboratory gas analysis method for accelerated measurement of formaldehyde release from uncoated and coated wood-based panels. Adopted by CEN (superseding the 2020 edition), the standard describes a controlled-chamber test in which air drawn from the chamber is passed through absorbers and the captured formaldehyde is quantified to give emissions expressed in mg/m2·h. The procedure is also suitable for related materials such as edge bands, floor coverings, foams, foils, laminated, veneered and coated wood products.

Key topics and requirements

Test principle: Specified test piece area placed inside a controlled chamber (temperature, humidity, airflow, pressure) - chamber air is sampled continuously through gas wash bottles filled with water to absorb formaldehyde.

Analytical methods: Photometric or fluorimetric determination of formaldehyde in absorber solutions; the 2023 revision adds laser spectroscopy as an additional analytical option.

Reagents: Analytical-grade reagents (examples in the standard include acetylacetone, ammonium acetate, commercial formaldehyde solutions, iodine, sodium thiosulphate, NaOH, H2SO4, starch). Premixed reagents (see ISO 12460-4) are referenced as optional.

Apparatus: Key components specified include gas wash bottles, air pump or mass flow controller, dust/formaldehyde filters, chamber (diameter 90–100 mm; internal volume (4 000 ± 200) ml), heating/thermostat, flow measurement, pressure and temperature monitors, and inert test piece holders.

Sampling & preparation: Procedures for sampling, cutting and selecting test pieces for factory production control, type testing or dispute cases are covered.

Results & reporting: Calculation methods to express formaldehyde release (gas analysis value and emission report value), moisture content determination and required test report content.

Applications and users

Intended for testing laboratories, manufacturers of wood-based panels and coated products, certification bodies, regulators and product safety teams for:

Type testing and product development (R&D)
Factory production control and quality assurance
Demonstrating compliance with formaldehyde emission limits and indoor air quality requirements
Assessing emissions from auxiliary materials (edge bands, laminates, foams)

Useful when specifying product performance in procurement, labeling, CE/national conformity, or indoor air quality assessments.
