--- Increasing the normative references YC/T 145.10 tobacco flavor sampling;
--- Increasing the standard alkaline solution of sodium hydroxide standard solution used for the titration;
--- Increasing the high concentration of standard solution of sodium hydroxide and potassium hydroxide in ethanol standard solution;
--- Increasing the measurement results of significant digits requirements;
--- Increasing the content of the test report;
--- Increased testing methods automatic titrator.
