Summary
This European Standard specifies a method for the determination of the total polyethylene glycol (PEG) content of 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 for concentrations of PEG higher than approximately 0,1 g/100 g of the laboratory sample.
