Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 3002-2004 "high temperature refractory refractory strength test method", compared with the GB/T 3002-2004, The main technical changes are as follows. --- Reference standard increased GB/T 4513.5, GB/T 4513.6 and GB/T 7321; --- Increase Note. "For other sizes of the sample, the span can be adjusted accordingly"; --- Removed the provisions of paragraph 5.3.2 and Appendix A of the temperature distribution measurement; --- Equipment to increase "vernier caliper"; --- Increase "the preparation of shaped products in accordance with GB/T 7321 for"; --- Increase "amorphous refractory preparation in accordance with GB/T 4513.5"; --- Increase "the minimum length of the sample is 100mm, the minimum width and height of 10mm." --- Increase the "amorphous refractory sample size in accordance with the relevant provisions of GB/T 4513.6 implementation." This standard uses redrafted Law Amendment uses IS05013.1985 "refractory products high temperature flexural strength test method." This standard compared with ISO 5013.1985 in the structure there are more adjustments, Appendix A lists the standard and ISO 5013.1985 Section number control list.
