This standard is equivalent to the international standard IS1061! The determination of the density of carbon black pulp with rubber is a revision of the national standard 6B/T14853.1\1993 for the determination of the density of carbon black pulp for rubber. This standard can be increased by 5) ±133:1: if the result is reached.
This standard is the same as /T1432.1! 3 main technical differences, \ one? The increase in the rate of use must be noted in the cup, and the density must be noted in the effective value P. (kg/m3 or (m3) on the brand. The quality of the fiber is specified in the regulations. This standard is implemented from the beginning, replacing CB/T14853.1-15. The National Bureau of Petroleum and Petrochemical Industry has invested in this standard, and this standard is issued by the National Technical Committee for Standardization of Rubber and Rubber Products Carbon Black. This cup should be approved by the unit, and the unit should be selected from the China Carbon Black Industry Research and Design Institute. This standard should be issued by the unit: The case is green, and the seedlings are explained. This standard was first issued on December 1993. GR/T 14853.1—2002
The International Organization for Standardization (ISO) is a worldwide federation of national standards bodies (ISO member bodies). The work on international standards is usually conducted by 10 technical committees. All member bodies interested in the subject matter have the right to participate in the committees established by the ISO. Governmental and non-governmental organizations with links to the ISO may also participate in the work. In all areas of technical standardization, the ISO Center closely cooperates with the International Electrotechnical Commission (ISOC) to adopt technical changes. International Standards are finalized and must be voted on by the issuing body: when published as an international standard, at least 75% of the members must vote.

GB/T14R53.72002 Carbon for stock production technology 3 Method Summary
Calculate the density of carbon by weighing the known volume. 4 Instruments and equipment
4.1 Determine the density: The volume is 1000cm, the diameter is <1001103mm, the pouring rate is required to be highly consistent, unchanged, and without any lower than the standard. Other volumes can also be used, but the test results are required to be consistent. 42 ruler or ruler, at least 13) m long, 4.3 square: accuracy is 0.1g
5 Sampling
Control G3778 is determined for detailed sampling.
6.1 The sample will be placed 5U above the edge of the density cup, roughly in the center of the density cup, so that it forms a quasi-circular body above the density ring. Move the point eight or scraper into a vertical state, the purple paste density will be the edge of the work, the density cup three and the carbon black is scraped flat, the surface is flat,
6.2 You measure the density board filled with carbon black, let it reach 1.1K to calculate the mass of black, the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China approved on May 29, 2002, implemented on December 1, 2001
