Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. This standard replaces GB/T 5071-1997 "refractory true density" compared with GB/T 5071-1997, Technical Changes are as follows. --- Increasing the gas comparison pycnometer method, modify using ASTMC604-2007 "refractory true specific gravity test methods for gas ratio Representing hydrometer Law "; --- Increasing the proportion of true definitions; --- Revised Appendix A; --- Modify the rounding principle test results. This standard uses redrafted law revision using ISO 5018. 1983 "Determination of true density refractory." This standard and ISO 5018. 1983, compared with more adjustment in the structure, listed in Appendix B of this standard and ISO 5018. 1983's Reg number control list. This standard and ISO 5018. 1983 technical differences are as follows. --- On normative references, this standard has been adjusted technical differences, in order to adapt our technical conditions, the adjusted situation Focus is reflected in the status of Chapter 2, "Normative references", the specific adjustments are as follows. ● Modify with international standards of GB/T 18930 replaced by ISO 5018. 1983 references ISO 836; ● increase cited GB/T 17617; ● Remove the ISO 5018. 1983 references ISO 5022; ● increase cited GB/T 10325; ● Remove the ISO 5018. 1983 references ISO 565; ● increase cited GB/T 6003.1; ● increase cited GB/T 8170. --- Increased gas comparative hydrometer method. This standard by the National Standardization Technical Committee Refractories (SAC/TC193) and focal points. This standard was drafted.
