Foreword

This standard was drafted in accordance with the rules of GB/T 1.1-2009 raised. This standard uses redrafted Law Amendment uses ISO 20502.2005 "Fine ceramics (advanced ceramics, advanced technical ceramics) Fine Ceramics Coating Adhesion Test methods Scratch "(MOD). This standard and ISO 20502.2005, compared with more adjustments in the structure, listed in Appendix A of this standard and ISO 20502.2005 The reg number control list. This standard and ISO 20502.2005 technical differences exist compared to the terms of these differences have been involved in the outside by a blank page position Opposing vertical single line (︱) were marked, Appendix B gives a list of corresponding technical differences and their causes. Modify the use of ISO 20502.2005, the standard to do this, the following editorial changes. --- Using the international standard amendments (TechnicalCorrigendum1); "." --- With a decimal point instead of a comma as the decimal point, ""; --- Deleted international standards foreword.
