This standard is equivalent to the international standard 11:1 Determination of heating loss of carbon black for rubber compounding agents and is adjusted from the user standard GB/T3760.51S2 Determination of heating loss of carbon black. This standard is consistent with the technical requirements of SC1126:1992. The method is a general method. In the "standard application" chapter, the color requirement and the block image are added. -6.7 Note that the block to be weighed is 1. This standard stipulates that the test results are used for revision. The main technical differences between this standard (GB/3780.81952 standard) are: the actual measurement of heat S2 (1 (2) 105! 2) is sufficient. In 6.2, "add the added value of the company" is added. The reference standard GBT817-1! 87*.

sO Foreword
International Organization for Standardization (ISO) is a world organization that members of the International Organization for Standardization (IS). The work of formulating international standards is usually carried out by technical committees of IS. All members of the committees established by the committees have the right to participate in the relevant technical requirements. International organizations, both governmental and non-governmental, in contact with ISO may also participate in this work. In all aspects of electrotechnical standardization, SC cooperates closely with the International Electrotechnical Commission (IEC). The draft international standards adopted by the technical committee shall be sent to the member groups for voting. When the international standard is issued, at least 75% of the member groups interested in voting shall be required to vote.

3 Summary of the method
The weighed hot test sample is heated at 105 °C for 1h in a weighed temperature. After cooling to the required volume in the detonator, calculate the heating reduction ratio.

Weigh the sample (m2) to an accuracy of (1 mg). 6.2 Weigh the sample (m2) to an accuracy of 0.1 mp±, and weigh about 1 mg. 6.3 Place the sample in a desiccator and place in a desiccator. Bottle, dry for 1h at (1u5+2)T or 12312). 6. For printing, put the weighed product in a dryer, open the bottle, cool it down, weigh the milk (presumably, weigh to 0.1mg
1 can be tested, the skin will have the requirements according to the situation and only need to have the amount of splashing hot content of the bottle mouth to wake up the environment 7 to make the detailed product reach the air quality, 2 from the dryer and put the weighed product in the constant range to ensure the good quality, so as to avoid the blackening of the fire due to the change of H gas flow. The foil result is expressed by the mass percentage table, calculated according to formula 1): -m× 130
Where: m.
Weigh the weight of the bottle cap and the test tube before heating: weigh the weight of the bottle cap and the test tube after heating.
The test result is more than the effective value specified in GB3716G/T3732 or GB/T7C44, take the common value, and then connect (:K/T817U) to the test tube.
