Any other information on results incl. tables

The surface tension standard value of reference item (distilled water) is 72.7±0.2mN/m at 20℃。

According to the testing condition used in the definitive test, the surface tension of the reference item is 72.5 mN/m at 20℃. The testing

result is within the permissible error range of the reference item. So it is believed that the testing result of test item is credible.

Applicant's summary and conclusion

Conclusions:
According to The Guidelines for The Testing of Chemicals 115 Surface Tension of Aqueous Solutions (STATE ENVIRONMENTAL PROTECTION
ADMINISTARTION OF CHINA 2004), the surface tension of the test item is tested. The surface tension of the test item is 32.3 mN/m at 20℃
Executive summary:

According to The Guidelines for The Testing of Chemicals 115 Surface Tension of Aqueous Solutions ( STATE ENVIRONMENTAL PROTECTION ADMINISTARTION OF CHINA 2004), the surface tension of the test item is

tested. The test result of the test item is 32.3 mN/m at 20℃. At the same time, we validate the apparatus and testing method by reference item (distilled water) specified in the study plan.
