Foreword This Law is enacted for the implementation of “Environmental Protection Law of the People's Republic of China” and "Law of the People's Republic of China on Prevention and Control of Pollution From Environmental Noise" and for the purpose of preventing and d This standard is the first revision of "Standard of noise at boundary of industrial enterprises" (GB 12349-90). Compared with the primary standard this national standard is mainly revised in the following parts: Combine “Standard of noise at boundary of industrial enterprises" (GB 12348-90) and standard the name will be changed to “Emission standard for industrial enterprises noise at boundary"; Application scope background value and correction table of the standard have been revised; Supplement noise limit value measuring condition measuring point's location measuring point'’s layout and measuring record of class 0; Increased some part of terms and definitions room noise limit value background noise measurement measurement result and measurement result evaluation content This standard was firstly promulgated in 1990 and this version is the first revision. From the implementation date of this standard “Standard of noise at boundary of industrial enterprises" (GB 12348-90) and “Method of measuring noise at boundary of industrial enterprises* (GB 12349-90) will be replaced by this standard. This standard was organized and drawn by the Technical Standard Department of the Ministry of Environmental Protection. The drafting organization of this standard: Environmental Monitoring of China Tianjin Environmental Monitoring Center Fujian Environmental Monitoring Center. This standard was approved by the Ministry of Environmental Protection on July 17 2008. The standard will be implemented on October 1 2008. This standard is interpreted by the Ministry of Environmental Protection.
