Scope: This European Standard specifies a method for the determination of the polyethylene glycol(PEG) content in aromatic and aliphatic non-lonic surface active agents of the type R•(O•C2H4)POH;where P is the mean ethylene oxide(EO) value.It is applicable to all ethoxylated products soluble in methanol or methanol/water mixture.This method applies to PEG concentrations as mass fraction greater than or equal to 0.1%.The method is not applicable to PEG whose molar mass is lower than 400g/mol. Monomeric ethylene glycol, diethylene glycol, triethylene glycol and glyceroll are not detected.
