中文摘要	人造板是室内甲醛的主要来源;测试其甲醛散发量有助于评估人造板对人体的健康影响。本文对比分析了常用的人造板甲醛散发量测试方法,包括穿孔法、广口容器法、干燥器法、气体分析法、气候箱法、FLEC法和C-history法等.穿孔法仅能获得人造板的甲醛总含量,而非总散发量;气候箱法测试结果能直接反映人造板的真实散发情况,但测试周期长,代价大;C-history方法采用密闭舱测试人造板散发关键参数,可预测人造板真实散发特性,缩短测试时间。此外,不同方法的预处理条件和测试条件明显不同,因此不同方法测试结果的相关性及其测试误差值得研究.; Determining formaldehyde emission from wood-based board is important for wood-based board is the main source of indoor formaldehyde,which affects people's health.This article presents a comprehensive comparison of commonly used test methods,including perforator method,flask method,desiccator methods,gas analysis method,chamber method,FLEC method and C-history method.The formaldehyde content measured by the perforator method is the total formaldehyde content,but not emittable formaldehyde.The chamber method can directly reflect the real emission characteristic of wood-based materials;however it is time and money-consuming.Using C-history method,the characteristic parameters of wood-based materials can be obtained simultaneously in short time,which can be used to predict the real emission.Besides,pre- and test conditions of these methods are different,this results in the need for comparing the agreement of these methods.
