Foreword

This standard replaces GB/T 14495-1993 "wooden surface roughness comparison specimen." This standard compared with GB/T 14495-1993, the main contents of modification are.

--- According to GB/T 1.1-2000 Standardization Guide Part 1: Structure and standard writing rules, made some editorial Modify, add standard foreword;

--- In the standard technical content, such as. terms of standard names, terms and other parameters, have made consistent with the new surface architecture standards;

--- Added Appendix B;

--- The standard Appendix A and Appendix B is an informative annex. This standard GPS location system in Appendix B.

1 Scope

This standard specifies the method of manufacturing a wooden surface roughness comparison specimens, the surface features, like block classification, surface roughness parameters assessment The method, structure size and marking.

This standard applies to wooden surface sand, milling, planing, vehicles, and other processing methods roughness comparison specimen. The sample block is used with the same grain structure Surface treatment is similar and the same processing methods were compared by visual and tactile assessment wooden surface roughness. It also serves as wooden pieces The surface roughness parameters selected reference.
