12 Test protocol - Desiccator KS M 1998, ISO , JIS A Pre conditioning : for constant mass, sustain samples at (20 ± 2) ℃, (65 ± 5) % - Desiccator test : 2 sets of desiccators, specimens installed, keep at 20 ℃ during 24 hours - Analysis : Treat water sample in each desiccators for absorbing HCHO by acetylacetone method & analyze the concentration with the UV/vis spectrophotometer. Test procedure - Formaldehyde emission test for wood-based panels(MDF, PB, Plywood) & construction materials. - Test for evaluation the grade(E0, E1, E2) how much the products content formaldehyde. - Maximum emission mass because of enlarged cutting surfaces in specimen, not in final product. - No functional relations with indoor air concentration affected in real product. (especially, different test condition – temp., humidity and isolated chamber) specimen number as surface area keep in chamber for constant mass installation specimen with water keep in 20 ℃, 24 h (2 desiccators) instrument analysis after reaction
