Abstract:

According to the Europe standard (BS EN 717-2: 1995: Wood Based PanelsDetermination of Formaldehyde ReleasePart 2: Formaldehyde Release by the Gas Analysis Method), the thesis, on the basis of a fully study and analysis, designed and made the gas analysis fast testing device for formaldehyde emissions. The device, which had the Siemens S7-200 PLC CPU 224 as central control unit and the MCGS as manmachine program, is featured largely in higher precision, higher speed and powerful antiinterference. It also decreased the time of testing formaldehyde release from 3～28 d to 4 h, thus it could save lots of human, material and financial resources.

Key words: formaldehyde release, fast test, gas analysis, PLC, MCGS
