The Machinery Industry Standard of the People's Republic of China JH 8551-1997 Noise Limits for Rock Drilling Machinery and Pneumatic Machinery Published on April 15, 1997 The Ministry of Machinery Industry of the People's Republic of China Implemented on January 1, 1998 JB8551-1997 Corrected 10087CC187B480187J48287, corrected 10087CC187B480187J48287, added 14 minor items, and made the noise limits of 17 series of existing products consistent with their corresponding product standards. At the same time, the three standards were combined into one standard to facilitate the implementation of the three standards, and the name of the standard was coordinated with the name of the relevant standards of this profession. This standard is proposed and organized by the National Mechanical and Pneumatic Industry Standardization Technical Committee: 1. The drafting unit of this standard is Tianshui Mechanical and Pneumatic Tool Research Institute. The main drafters of this standard are: Xin Yu, Zhang Yucheng, Chen Lanfang, Wei Wanjiang. This standard was first issued in March 17, and this is the first revision. 1 Model Figure Machinery Industry Standard of the People's Republic of China Rock Drilling Machinery and Pneumatic Tools Noise Limit This standard specifies the common noise limit values of pneumatic tools and other products, JB 8551-1997 84003-134604 ZBJ4B 00---[48 (0267 This standard includes all kinds of pneumatic rock drilling machines and pneumatic tools. The products include explosion-proof electric rock drilling machines for mining, pneumatic picks, pneumatic shovels, pneumatic fasteners, three-head rivet machines, pneumatic gauges, pneumatic grinders, impact-stop pneumatic alarms, pneumatic end screws, pneumatic augers, pneumatic oxygen-pulling machines, etc. Reference standards The following standards contain clauses and sections, which are not included in the standard. When the technical standard is published, the minor version is valid. All standards are not revised. All parties using this standard should explore the possibility of using the latest version of the following standards GES8-G J/T 5126--91 Rock drilling machinery and pneumatic two-soldier noise market force method engineering method dynamic music leaf!
