Foreword

This standard is identical with ISO 17565.2003 "Fine ceramics (advanced ceramics, advanced technical ceramics) --- monolithic ceramics at high temperatures bend Bending strength test method. " This standard and ISO 17565.2003 compared to do the following editorial changes. --- "ISO 7500-1", "IEC 60584-1" to "GB/T 16825.1", "GB/T 16839.1"; "." --- Decimal point instead of a comma as the decimal point, ""; --- Deleted international standards Appendix E. This standard replaces GB/T 14390-1993 "high temperature engineering ceramics bending strength test method." This standard and GB/T 14390-1993 compared to the main changes are as follows. The term --- heading "Engineering Ceramics" to "fine ceramics"; --- Increasing the terminology (see 3); --- Increased by principle (see 4); --- Sample size was changed to "for 30mm span test jig, sample length ≥35mm; for span test clip 40mm Tools, sample length ≥45mm "(1993 version 5.1; this version 6.1.1); --- Remove 2 (1993 edition Figure 2); --- Remove Figure 3 increased by 1 (1993 Version 2.2; 3.2 edition) Figure; --- Increasing the roll bar and the three-point bending and described four-point bending device (see 5.4.2 - 5.4.8); --- Increased sample processing (see 6.2); --- Increase test procedures detailed information and instructions (see 7); --- Increasing the accuracy and precision and intensity scale factor calculation results (see 9,11); --- Choice cancel the abnormal data method, an increase of Annex A (informative) described in Appendix B (normative) Correction chamfer Coefficient, Appendix C (normative) thermal expansion of the amendments to Appendix D (Informative Appendix) weibul scale factor.
