Other burning temperatures may be used with the agreement of both parties. 6.4 After the sample is completely ashed, close the furnace door to burn for 30min; take out the crucible; place onto the dry and clean porcelain plate beside the high temperature furnace and cool off for 3min; then cover the lid of the crucible; place into the desiccator to cool off to the room temperature. When opening the lid of the desiccator, the air shall be ensured to flow into slowly, so that avoid ash loss in the crucible due to strong airflow. Weigh the mass of the crucible, accurate to 0.1mg. 6.5 Place the crucible into a high temperature furnace for repeat burning until difference between two weightings does not exceed 0.3mg; record the smaller weighting value of m2. In order to avoid repeated operations, the ashing time of the sample shall be fully estimated during the burning period. 7 Test Data Processing The ash content of the carbon black shall be recorded by mass fraction of residue after burning of the sample, w; it shall be calculated as per Formula (1). Where. m0 – the mass value of empty crucible before sample-weighing, in g; m1 – the mass value of crucible and specimen before burning, in g; m2 – the mass value of crucible and residue after burning, in g. The calculation results shall be expressed by two figures after the decimal points; if there are multiple measurement results, take the average value; then round-off the value as per the report requirements or provisions of GB/T 3778, GB/T 3782, GB/T 7044 or GB/T 8170. 8 Precision 8.1 Repeatability In the same laboratory, the absolute difference between two independent test results obtained by the same operator using the same equipment, according to the same test method, and testing the same object independently in a short time shall be no more ......
