Foreword
This standard is based on the European standard EN860 "Safety Single Sided Woodworking Machine Tools" "Woodworking Press Planer" is a revision of JB5727-91 "Structure Safety of Single-sided Wooden T-Letron Beds". The technical content is basically consistent with EN860, and the limit value of the noise level of the machine tool during idle operation is increased. This standard is quite different from JB5727--91 in technical content. This standard replaces JB5727-91 from the date of implementation. Appendix A and Appendix B of this standard are both standard appendices. Appendix C and Appendix D of this standard are both reminder appendices. This standard was proposed by the National Woodworking Machine Tools and Tools Standardization Technical Committee. This standard is under the jurisdiction of Fuzhou Woodworking Machine Tool Research Institute. The unit responsible for drafting this standard: Fuzhou Woodworking Machine Tool Research Institute. The main drafters of this standard are: Zheng Li and Zheng Zongjian. This standard was first published on January 1, 1991. Machinery Industry Standard of the People's Republic of China
