This standard compared with GB/T 12717-1991 main changes are as follows. --- Increase in the content of the warning (see 3.1); --- Test Method for increasing the appearance (see 3.3); --- Increasing the test method, the technical content of the American Society for Testing and Materials standard odor ASTMD1296.2001 "volatile solvent Test "and diluent smell the same (see 3.5); --- Density test method is modified by the Wechsler scale method hydrometer method (1991 version 3.2, this version 3.6); --- Test Method for Acidity in the amount of alcohol solvent and sample size by 10mL modified to 20mL (1991 edition of 3.6.2, edition The 3.9.4); --- Canceled ester content of the test method saponification (1991 version 3.5); --- Acetate content, Test Method for increasing the alcohol content in capillary gas chromatography (see 3.10.1), increased capillary column Gas Chromatography typical chromatogram (see Appendix A.1); Test Method --- moisture increases the Karl Fischer coulometry (see 3.11.1). The Standard Appendix A, Appendix B is an informative annex. The standard proposed by China Petroleum and Chemical Industry Association. This standard by the National Standardization Technical Committee branch of organic chemistry (SAC/TC63/SC2) centralized. This standard was drafted.
