Foreword
This standard replaces GB/T 12717-1991 "industrial acetates Test Method."
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.
