Evaluation of equivalence of desiccator methods in the ISO and JIS standards

In ISO/TC89, the measuring method of formaldehyde emitted from wood-based materials was discussed, and the ISO standard of the desiccator method was enacted in 2008. There are some differences between the desiccator methods according to JIS and ISO standard and therefore, the experimental equivalence is not evident. In this study, equivalence of the cooling processes of the test solution was evaluated because the operational procedures in the JIS and ISO standards are different.
