Scope

Main technical content: 1. Scope This document specifies the classification, requirements, test methods, inspection rules, marking, packaging, transportation, and storage of mixed fatty acids. This document applies to mixed fatty acids obtained as a by-product during the hydrolysis and distillation process for producing fatty acids from natural plant (or animal) oils. 2. Terms and Definitions The following terms and definitions apply to this document: 2.1 Mixed fatty acids Mixed fatty acids obtained as a by-product during the hydrolysis and distillation process for producing fatty acids from natural plant (or animal) oils. 2.2 Low-acid value mixed fatty acids Low-acid value mixed fatty acids obtained from the distillation residue during the first or multiple hydrolysis and distillation processes for producing fatty acids from natural plant (or animal) oils. 2.3 Higher-acid value mixed fatty acids Higher-acid value mixed fatty acids obtained from the distillation residue and a mixture of some fatty acids during the hydrolysis and distillation process for producing fatty acids from natural plant (or animal) oils. 3. Classification Products are classified according to the production process and the components they contain, and are divided into low-acid value mixed fatty acids and higher-acid value mixed fatty acids.
