This section GB/T 3780 Part 2.

This section drafted in accordance with GB/T 1.1-2009 given rules.

This Part replaces GB/T 3780.2-2007 "Part 2 carbon black. Determination of oil absorption," compared with GB/T 3780.2-2007, the main technical changes are as follows.

--- Added the relevant reagents and materials (see 5.1, 5.3);

--- Modify the accuracy of the microtiter (see 6.5, 2007 version 11.1);

--- Added the "carbon black type listed in Table 1, the value of oil absorption are read curve fitting 70% of the maximum torque at the corresponding value" provisions more Surface and clear (see 8.1.9);

--- Increase the density of the provisions of the oil (see Appendix A, A.6);

--- Added "Evaluation of oil absorption chamber" (see Appendix E);

--- Removed the 2007 edition of Table C.1.
