新版《民用建筑工程室内环境污染控制标准》正式实施 这些仪器大有可为
p style="text-indent: 28px line-height: 1.75em "span style="font-family: 宋体, SimSun "2020年8月1日,新版《民用建筑工程室内环境污染控制标准》GB 50325-2020正式实施。该标准对建筑工程室内环境标准提出了新的要求。/span/pp style="text-indent: 28px line-height: 1.75em "span style="font-family: 宋体, SimSun "span style="font-family: 宋体 "相较于旧版标准,新版做了许多修订。首先,对于室内空气中污染物的检测,新增了甲苯和二甲苯两个检测指标,使得室内空气中污染物种类增加到/span7span style="font-family: 宋体 "种;增加了苯系物及挥发性有机化合物(/spanTVOCspan style="font-family: 宋体 ")/spanT-Cspan style="font-family: 宋体 "复合吸附管取样检测方法,进一步完善并细化了室内空气污染物取样测量要求。/span/span/pp style="text-indent: 28px line-height: 1.75em "span style="font-family: 宋体, SimSun "span style="font-family: 宋体 "此外,还对室内空气中污染物浓度限值严格要求。并对室内装饰装修设计提出了污染控制预评估要求及材料选用具体要求;对自然通风的/spanIspan style="font-family: 宋体 "类民用建筑的最低通风换气次数也提出了具体要求。/span/span/pp style="text-indent: 28px line-height: 1.75em "span style="font-family: 宋体, SimSun "span style="font-family: 宋体 "该标准还规定,幼儿园、学校教室、学生宿舍、老年人照料房屋设施室内装饰装修验收时,室内空气中氡、甲醛、氨、苯、甲苯、二甲苯、/spanTVOCspan style="font-family: 宋体 "的抽检量不得少于房间总数的/span50%span style="font-family: 宋体 ",且不得少于/span20span style="font-family: 宋体 "间;当房间总数不大于/span20span style="font-family: 宋体
