This International Standard specifies a method for the determination of the residual styrene monomer in polystyrene (PS) and impact-resistant polystyrene (PS-I) by gas chromatography. It may also be used for the simultaneous determination of other volatile aromatic hydrocarbons in PS and PS-I.<\/p>\n
