Distributing 'the Development and Revision Plan of NationaL Engineering ConstructionStandards in 2016".The standard compilation team has compiled thisstandard afterextensiveinvestigation and study,earnest summary of practical experience and extensive solicitation of opinionswith reference to relevant international standards and foreign advanced standards.The main technical contents of this standard include:general provisions.terms and symbols,building materials,survey and designing for building engineering.construction.inspection andacceptance,etc.The main technical contents revised in this standard are outlined below:1.Toluene and xylene are added into indoor air pollutants:2.The classification of decorating materials is refined,and the limit and measurement method ofpollutant content (release amount)in some materials are adjusted:3.Theenvironmentaltestchambermethodanddesiccormeasurementofformaldehyde emission from wood-based panels are retained4.The requirementsfor pollution controlpre-assessmaterialselection for indoordecoration design are specified:5.The requirementsthe minimum ventilatof class I civil buildings with naturalventilation are specified:6.The comprehensive radon prevention-measures of buildings are improved;7.More stricter pollutioncontrol requirements forthedecorationofpreschools/nurseries,kindergartens,school classrooms,and student dormitories are specified;8.The test method for radon concentration in indoor air is defined.9.The pollutant concentration limit in indoor air is re-determined;10.The sampling and test method for benzene series and total volatile organic compounds(TVOC)with T-C composite adsorption tubes are added,and the sampling and measurementrequirements for indoor air pollutants are further improved and refined.The provisions printed in bold type in this standard are mandatory ones and must be implementedstrictly.This standard is under the jurisdiction of,and its mandatory provisions are interpreted by theMinistry of Housing and Urban-Rural Development.Henan Provincial Academy of Building ResearchCo.,Ltd.is in charge of the explanation of specific technical contents.The relevant options and advicederived from the process of implementing this standard can be posted or passed on to Henan ProvincialAcademy of Building Research Co.,Ltd.(Address:No.4 Fengle Road,Zhengzhou
