--- modified the principle (see Chapter 3, Chapter 4 of the.2007 edition);
--- "distilled water" modified to "three water", "50 ℃" modified to "45 ℃ ± 2 ℃" (see 6.2,.2007 version 7.2);
--- Added "under full agitation" control conditions (see 6.3, 7.3 of 7.3);
--- Added filter paper verification contents (see Chapter 4 and Appendix A).
This standard is proposed by the China Petroleum and Chemical Industry Association.
This standard is under the jurisdiction of the National Dye Standardization Technical Committee (SAC/TC134).
