Foreword

This standard solvent extraction method and elliptically polarized reference ASTMA623M-08 "Standard Specification for General tinplate" Appendix A6 system Set, increasing the hydrophilic balance method. This standard compared ASTMA623M-08 Appendix A6, the main changes are. --- No automatic delete function ellipsometer tone given program; --- Increasing the terms and definitions; --- Test device portion of the solvent extraction method increases the balance and distillation apparatus; --- Increasing the distillation apparatus, structural principle volume sampling device, such as an ellipsometer schematic; --- Calculation of the test results complement rounding off content. This standard by the National Steel Standardization Technical Committee (SAC/TC183) centralized. This standard was drafted. Wuhan Iron and Steel (Group) Corporation, Metallurgical Industry Information Standards Institute. The main drafters of this standard.
