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 /p p 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 /span 7 span style=" font-family: 宋体 " 种;增加了苯系物及挥发性有机化合物( /span TVOC span style=" font-family: 宋体 " ) /span T-C span 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 /p p 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 /span I span 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 /p p 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、 /span TVOC span style=" font-family: 宋体 " 的抽检量不得少于房间总数的 /span 50% span style=" font-family: 宋体 " ,且不得少于 /span 20 span style=" font-family: 宋体 " 间;当房间总数不大于 /span 20 span style=" font-family: 宋体 " 间时,应全数检测。相较于老版标准,污染控制要求更加严苛。 /span /span /p p style=" text-indent: 28px line-height: 1.75em " span style=" font-family: 宋体, SimSun " span style=" font-family: 宋体 " 本标准中还明确了民用建筑室内空气中氡浓度检测宜采用泵吸静电收集能谱分析法、泵吸闪烁室法、泵吸脉冲电离室法、活性炭盒 /span - span style=" font-family: 宋体 " 低本底多道γ谱仪法。 /span /span /p p style=" text-indent: 28px line-height: 1.75em "
