室内物品和家具VOC散发环境舱设计思考和实践
Chamber for determination of volatile organic compound emissions from indoor products and furniture: Design consideration and practice
摘要：
欧美发达国家普遍采用环境舱对室内物品及家具VOC散发进行测试。介绍了环境舱法的测试原理，包括通风舱和密闭舱的测试原理。国外均采用通风舱进行测试，测试时间通常为7～28 d，而清华大学提出的密闭舱C-history方法可将测试时间缩短到3 d以内。基于环境舱测试原理介绍了一种环境舱设计方案，并据此制作了30 m³全尺寸环境舱，所建环境舱既能开展通风舱测试又能开展密闭舱测试。采用LIFE标准散发样品对环境舱的综合性能进行了测试，测试结果显示通风舱回收率为86.7%，密闭舱回收率为90.6%，满足ISO 16000-9和ASTM D6670的要求。
Abstract：
he chamber is generally used to test VOC emissions from indoor products and furniture in European countries and the US. Presents the fundamentals of chamber methods, including ventilated chamber method and closed chamber method. Testing time of the ventilated chamber method adopted aboard is 7 to 28 days in general. The C-history method, developed by Tsinghua University, using closed chamber can shorten the testing time to 3 days or even less. Based on the fundamentals of chamber methods, presents a design scheme of the chamber according to which a 30 m³ full scale chamber was built. This chamber can be used as both ventilated and closed chamber. Evaluates its performance by LIFE standard reference and the testing results show that the recovery rate of ventilated chamber is 86.7% and closed chamber is 90.6%, satisfying the demand of standard ISO 16000-9 and ASTM D6670.
