Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1: Structure and drafting rules for standardization documents" Drafting.

This document is equivalent to ISO 19085-1:2021 "Safety of woodworking machine tools — Part 1: Common requirements".

The following minimal editorial changes have been made to this document.

--- To coordinate with the existing standards, the name of the standard is changed to "Common Safety Requirements for Woodworking Machine Tools";

--- Corrected the reference errors in 7.3.1n), 6.8 was changed to 6.7, 6.9 was changed to 6.8;

--- Corrected the table numbering error in Appendix A, and modified Table 1 to Table A.1.

1 Scope

This document provides the safety requirements and measures for continuous woodworking machine tools (hereinafter referred to as machine tools) to reduce the risk of accidents during operation, adjustment, these safety requirements and measures are prepared by the manufacturer for most machine tools.

See the commonly used conditions under the intended use within the scope, while also taking into account reasonably foreseeable misuse.

This document applies to machine tools for machining solid wood and materials with similar physical properties to wood, using manual feed or mechanical feed.

This document is intended to be used in conjunction with the safety requirements for specific machine tools (the safety standards for specific machine tools cover all significant hazards of that type of machine tool).

The hazards covered by this document are listed in Appendix A.

This document does not apply to machine tools used in potentially explosive atmospheres and to machine tools manufactured before the date of publication of this document.
