Foreword

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents".

Drafting.

This document is modified to adopt ISO 20407:2017 "Fine ceramics (advanced ceramics, advanced technical ceramics) under constant amplitude conditions at room temperature".

Test methods for tensile and shear fatigue properties of ceramic bond interfaces.

This document has undergone significant structural adjustments compared to ISO 20407:2017.A comparison of the structural numbering changes between the two documents is provided below.

See Appendix A for the table.

This document differs significantly from ISO 20407:2017.The relevant clauses are indicated in vertical margins.

Single lines (|) are indicated. A summary of these technical differences and their causes can be found in Appendix B.

The following editorial changes have been made to this document.

---To align with existing standards, the standard name has been changed to "Test for Room Temperature Tensile and Shear Fatigue Properties of Fine Ceramics Interfaces under Constant Amplitude".

The cross-multiplication method for testing;

---Added sub-topics for Figures 4 and 5.

---Add "Width should not exceed 1mm" (see 7.4).
