Foreword

This standard replaces GB/T 6155-1985 "Determination of the true density of the carbon material" and GB/T 6156-1985 "Carbon Materials true porosity Method for determination. " This standard and GB/T 6155-1985 The main differences are as follows. --- Consolidated standard name to the true density of carbon material true porosity rate determination method; --- The two standards the same content into the same section; --- The experimental error to precision. The standard proposed by China Iron and Steel Association. This standard is under the jurisdiction of the National Steel Standardization Technical Committee. This standard was drafted. Metallurgical Industry Information Standards Institute, Sinosteel Jilin Carbon Company. The main drafters of this standard. Sun Wei, Alice Zhang Feng, Zhang Ying. This standard replaces the standards previously issued as follows. --- GB/T 6155-1985; --- GB/T 6156-1985. Carbon material true density and true porosity rate determination method
