Comparison of Desiccator Methods between New and Old Version of GB/T 17657 for Testing Formaldehyde Emissions from Wood-based Panel Products
To promote implementation of the National Standard GB/T 17657-2013, the 2013 version and1999 version of GB/T 17657 were compared. Formaldehyde emissions from blockboard, plywood and wooden door sheets were tested by desiccator methods according to the new and old version of the standard. The results indicated that the new version of the standard was more systematical and comprehensive by clarifying requirements of sample numbers, conditioning, blank test, formaldehyde solution storage conditions and chromogenic reaction. They concluded that the new version had higher testing accuracy and was easy to be standardized.
