          Civil construction insulation systems and external decorative fire Interim Provisions (public through word [2009] No. 46)
           

          Ministry of public security 
          Housing and Urban-Rural Development 
          Public through word [2009] No. 46 
          On the issuance of "civil external facade insulation systems and fire Interim Provisions" 
          Provinces, autonomous regions and municipalities Public Security Bureau, Bureau of Housing and Urban Construction Department, Construction, Jiangsu, Shandong Provincial Construction Authority, the Public Security Bureau of Xinjiang Production and Construction Corps Construction Bureau: 
          To effectively prevent the building insulation system fire accident, the Ministry of Housing and Urban jointly developed a "civil construction facade insulation systems and fire Interim Provisions", issued to you now. Please combined with actual work, conscientiously implemented. After the revision of the relevant standards, according to relevant regulations issued by the implementation of standards.
