FORMALDEHYDE EMISSION-A COMPARISON OF DIFFERENT STANDARD METHODS

摘要

This technical bulletin gives a comparison between European test methods e.g. chamber (EN 717-1), gas analysis (EN 717-2), flask (EN 717-3) and perforator method (EN 120) with Japanese test methods e.g. desiccator (JIS A 1460 and JAS 233) and small chamber method (JIS A 1901) for solid wood,particleboard, plywood and medium density fibreboard.The variations between the results from different methods are explained by specific differences in test conditions.The need for harmonisation is obvious, and use of e.g. the standardisation within ISO to work for such an international harmonisation should be encouraged.
