ASTM D5137-07 (2021) "Standard Specification for Hexyl Acetate" specifies the technical requirements for the chemical purity, physical properties and test methods of hexyl acetate. Hexyl acetate is a compound commonly used in Coatings, varnishes, gluing agents and industrial solvents, and its mass is critical to product performance and safety. The standard specifies key parameters such as minimum purity, density, Refractive index and acid value of hexyl acetate, and describes in detail the procedures and conditions for related tests. By implementing this specification, the conformity and Reliability of hexyl acetate in industrial applications can be ensured, providing technical support for product production, quality control and performance optimization.
