摘 要 ：针对国内室内空气质量差 ，内墙涂料产品TVOC释放性能测试标准的空白，研制了60 L小型环境舱应用于室内涂料TVOC释放量的检测，舱体性能优良并已通过计量；参考国外标准探讨了利用环境舱模拟室内环境测定内墙涂料TVOC释放量的标准方法，通过实验确定了关键参数，并选用不同配方样品以该标准方法进行验证试验。结果证明 ：该方法可以判断内墙涂料的TVOC 释放性能的优劣，并具有 良好的可操作性和可靠性，对我国内墙涂料TVOC释放量检测标准的建立具有很好的参考价值。同时得出 TVOC与VOC之间没有确定的相关性。

Abstract ：Since there is no specific and authorized test method for determining the VOC emission from interior coatings in China ，a small —scaleen ．vironmental chamber with 60 L has been designed applicable for the determination of VOC ．The chambers perform well and pass the examination of metrological certification by the specifi cauthorized agency．This paper describes the experi ments on how to determine the key parameters and final optimized procedure ， including the verifi cation tests via a large quantity of different paint formulations．Experi mental results show that the standard method has a good operability and reliability ，which can be useful for establishment of the domestic determinati on standard for TVOC in interi or coatings．
Key Words ：environmental chamber；TVOC ；emission ；indoor air quality ；interior coatings
