摘　　要：环境舱系统被广泛用于测试建材挥发性有机化合物(VOC)的散发速率及散发关键参数,然而其测试结果的准确性亟待检验。介绍了评价环境舱系统测试建材VOC散发准确性的方法,综述了适用于环境舱系统的VOC标准散发样品——直接蒸发式、PMP膜式和液-膜式标准散发样品。Environmental chamber systems are wildly used for measuring the emission rate and emission characteristic parameters of volatile organic compound （VOC） emitted from building materials. However, the measurement accuracy is needed to evaluate. Presents the methods＇for evaluating the measurement accuracy of VOC emissions. Reviews the VOC emission references, such as the direct evaporative emission reference, the PMP film emission reference and the liquid-film emission reference.
