Anotácia textu normy ASTM D3735-22 :
This specification covers four types of moderately volatile hydrocarbon solvents that are mainly aliphatic in composition and normally petroleum distillates, and are commonly referred to as VM&P naphthas used primarily by the coatings industry. Materials shall be available in the following types: Type I, regular; Type II, high flash; Type III, odorless; and Type IV, low aromatics. Specimens shall undergo tests that shall examine their conformance with specified values of the following physical and chemical properties: appearance; bromine number; color (Pt-Co units); aromatics; copper corrosion; distillation (initial boiling point, 50 % recovered, and dry point); flash point; Kauri-butanol value; odor; and apparent specific gravity.
