This standard specifies the method for the determination of the content of plasticizer dibutyl phthalate formic acid (DBP) or dioctyl phthalate formic acid (DOP) in cast organic Glass by ultraviolet spectroscopy. It is suitable for the determination of the content of plasticizer DBP or DOP in cast colorless transparent organic Glass. The content of plasticizer is calculated by working Linear dispersion method according to the absorption characteristics of plasticizer in trichloromethane solution under the action of ultraviolet light. Reagents include DBP, DOP, trichloromethane and standard solution. The instrument is ultraviolet spectrophotometer. The sample should be a particle or powder randomly removed from the organic Glass.
