Scope

Scope: This document specifies the terms and definitions, classification and labeling, technical requirements, inspection methods, inspection rules, and packaging, marking, transportation, and storage of wood vinegar liquid. This document applies to agricultural, industrial, and civilian wood vinegar liquids. (Wood vinegar liquids produced from biomass such as herbs, fruit shells, and rice husks can be referenced for use.) Main technical content: 3. Terms and definitions The following definitions apply to this document. 3.1 Wood vinegar liquid Wood vinegar liquid is an acidic liquid containing phenols, acids, alcohols, ketones, aldehydes, and other organic components, obtained by collecting, condensing, cooling, and separating gases produced during the pyrolysis of natural wood, wood processing residues, and agricultural and forestry residues (such as fruit branches).
