Defines the procedure for determining the polyethylene glycol (PEG) content in aromatic and aliphatic non-ionic surface active agents of the type R-(O-C2H4) p OH; where p is the mean ethylene oxide (EO) value. It applies to PEG concentrations as a mass fraction greater than or equal to 0.1%. The procedure does not apply to PEG whose molar mass is lower than 400 g/mol. Monomeric ethylene glycol, diethylene glycol, triethylene glycol and glycerol are not detected.
