Surface active agents - Determination of polyethylene glycol content in nonionic ethoxylated surfactants - HPLC method
Surface active agents - Determination of polyethylene glycol content in nonionic ethoxylated surfactants - HPLC method
This International Standard specifies a method for the determination of the polyethylene glycol (PEG)
content in aromatic and aliphatic non-ionic surface active agents of the type R-(O-C2H4) n OH; where n
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 %. This International Standard is not applicable to PEG whose molar mass is lower than
400 g/mol. Monomeric ethylene glycol, diethylene glycol, triethylene glycol, and glycerol are not detected.

Površinsko aktivne snovi - Določevanje polietilen glikola v neionskih etoksiliranih površinsko aktivnih snoveh - Metoda HPLC
Ta mednarodni standard določa metodo za določevanje vsebnosti polietilen glikola (PEG) v aromatskih in alifatskih neionskih površinsko aktivnih sredstvih tipa R-(O-C2H4) n OH; pri čemer se uporablja povprečna vrednost etilen oksida (EO). Uporablja se za vse etoksilirane proizvode, topne v metanolu ali mešanici metanola in vode. Ta metoda se uporablja za koncentracije PEG kot najmanj 0,1-odstotni masni delež. Ta mednarodni standard se ne uporablja za PEG z molsko maso manj kot 400 g/mol. Prisotnost monomernega etilen glikola, dietilen glikola, trietilen glikola in glicerola se ne ugotavlja.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any
patent rights identified during the development of the document will be in the Introduction and/or on
