<strong>　　一、GB/T18883与GB50325室内空气质量执行标准</strong></div><div> 　　GB/T18883-2002《室内空气质量标准》，由卫生部制定，检测要求门窗关闭时间为12小时，主要用于衡量房屋是否合乎人类环境健康要求，不受约束力，只是指导性标准。</div><div> 　　GB50325-2010《民用建筑工程室内环境污染控制规范》，由建设部制定，检测要求门窗关闭时间为1小时主要用于民用建筑工程和室内装修工程环保验收检测，具有强制性。</div><div> <strong>　　二、GB/T18883与GB50325室内空气质量标准的区别</strong></div><div> 　　1、针对性的区别GB/T 18883是国家环保总局和卫生部发布的国标推荐性标准，是一种指导性标准，是人居环境健康尺度，对建筑商、装修商、家具商没有约束力；GB50325是建设部发布的强制性标准，是建筑、装修验收标准，对建筑商、装修商具有强制性，要求是在项目竣工后1个月以后监测。该标准规定，建筑工程、装修工程必须履行环保验收达标才能交工，严禁不达标房屋交付使用。</div><div> 　　2、指标值的区别GB/T 18883标准涉及室内环境物理性、化学性、生物性、放射性共19项指标，GB50325规范只对甲醛、苯、氨、TVOC（总挥发性有机物）和氡等5个项目进行了限定。两个标准重叠的项目的限定值依甲醛、苯、氨、TVOC（总挥发性有机物）和氡的顺序依次为0.10/0.08 、 0.11/0.09 、 0.20/0.20 、 0.60/0.50 、 200/200。从指标上来看GB50325比GB/T18883数指要求高。</div><div> 　　3、检测条件不同按指标值来看，GB50325规范比GB/T 18883标准的要求还要高一点，但事实上，落实到检测条件的时候，GB50325比GB/T 18883要严重宽松。前者规定只关闭门窗1小时就进行检测，后者则规定要关闭门窗12小时之后进行。</div><div> <span style="color:#008000;">　　总之空气检测本身就具有多项指标，采用适合自己环境的空气质量标准，更好的运用到室内空气检测过程中，才可以得到更为准确的结果。目前国内环保公司一般都采用GB50325-2010的标准执行。</span></div><div style="text-align: center;"> <table align="center" border="1"
