The authors summarized current test methods, including gas analysis, desiccator, extraction and chamber methods, of formaldehyde emissions from wood-based flooring products used in a ground heating system. Characteristics of formaldehyde quantitative test methods, including acetyl acetone, chromotropic acid and phenol reagent methods, were also compared.It was proposed that chamber and chromotropic acid methods were the most suitable for measuring formaldehyde emissions from wood-based flooring products used in a ground heating system.It is suggested that the equilibrium treatment conditions of the testing sample and parameters of the simulated ground radiant heating device in the chamber be determined according to actual environment temperature characteristics for ground radiant heating.
