Foreword

This revised standard adopts ISO 1708. 1989 "Test conditions lathe accuracy test" (in English). This standard is based on ISO 1708. 1989 redrafted. Taking into account China's national conditions, adopting ISO 1708. 1989 When do the technical content changes. About the technical differences have been incorporated into the text and They are involved in terms of the margin identified by a single vertical line. A list of these technical differences, see Appendix. This standard also made the following changes. --- The "this International Standard" by "this standard"; --- Use the decimal symbol instead of as a decimal comma ",". ","; --- Deleted international standards foreword, introduction of international standards by way of expressing our language; --- To ISO 1708. 1989 and other international standards cited by international standards adopted in place of the corresponding standard; --- Chapter 1 expands the scope of the technical content; --- Title Chapter 3, "a brief description" to Chapter 4, "General requirements"; --- Chapter 4, the heading "Test conditions and tolerance" to Chapter 5, "Geometric tests" and Chapter 6, "Working accuracy test"; --- Chapter 5 to Chapter 8; --- Section 3, Chapter 7 and Appendix A to increase the content; --- Delete references Appendix A content.
