Surface active agents - Detergents - Determination of cationic-active matter content - Part 2: Cationic-active matter of low molecular mass (between 200 and 500) (ISO 2871-2:2010)

ISO 2871-2:2010 specifies a method for the determination of low-molecular-mass cationic-active materials such as monoamines, amine oxides, quaternary ammonium compounds and alkyl-pyridinium salts which have a main chain of 10 to 22 carbon atoms and not more than 6 other carbon atoms in the cation. The method is also suitable for other cationic-active materials.
The method is applicable to solids or to aqueous solutions of the active material. The method is not applicable if anionic and/or amphoteric surface active agents are present.

Tenside - Waschmittel - Bestimmung des Gehaltes der kationaktiven Substanz - Teil 2: Kationaktive Substanz niedriger Molmasse (zwischen 200 und 500) (ISO 2871-2:2010)

Dieser Teil von ISO 2871 legt ein Verfahren fest zur Bestimmung niedrigmolekularer kationaktiver Substanz, wie z. B. Monoaminen, Aminoxiden, ternären Ammoniumverbindungen und Alkylpyridiniumsalzen, die eine Hauptkette mit 10 bis 22 Kohlenstoffatomen und nicht mehr als 6 weitere Kohlenstoffatome im Kation enthalten.
Das Verfahren ist auch für andere kationaktive Substanzen geeignet.
Das Verfahren gilt für Feststoffe oder wässrige Lösungen der Aktivsubstanz, wenn die relative Molmasse der kationaktiven Substanz bekannt ist oder vorher bestimmt wurde, falls ihr Gehalt als Massenanteil in Prozent angegeben wird. Wenn mehr als eine Art kationaktiver Substanz vorliegt, kann ein Schätzwert der mittleren relativen Molmasse verwendet werden.
Das Verfahren gilt nicht, wenn anionische und/oder amphotere Tenside vorhanden sind.

Agents de surface - Détergents - Détermination de la teneur en matière active cationique - Partie 2: Matière active cationique à faible masse moléculaire (entre 200 et 500) (ISO 2871-2:2010)

L'ISO 2871-2:2010 spécifie une méthode de détermination des matières actives cationiques à faible masse moléculaire telles que les composés monoaminés, les oxyde d'amines, les ammonium quartenaires et les sels d'alkylpyridinium qui contiennent une chaîne principale de 10 à 22 atomes de carbone et au plus 6 autres atomes de carbone dans le cation. La méthode s'applique également à d'autres matières actives cationiques.
La méthode s'applique à la matière active à l'état solide ou en solution aqueuse. La méthode ne s'applique pas si des agents de surface anioniques et/ou amphotères sont présents.

Površinsko aktivne snovi - Detergenti - Določevanje kationsko aktivnih snovi - 2. del: Kationsko aktivne snovi z majhno molekulsko maso (med 200 in 500) (ISO 2871-2:2010)

Ta del ISO 2871 določa metodo ta določevanje kationsko aktivnih materialov z nizko molekulsko maso kot so monoamini, amino oksidi, kvartarne amonijeve sestavine in soli alkilpiridina, ki imajo glavno verigo od 10 do 22 atomov ogljika in ne več kot 6 drugih atomov v kationu. Metoda je prav tako primerna za druge kationsko aktivne materiale. Metoda velja za trdne snovi ali za vodne raztopine aktivnega materiala, kadar je relativna molekulska masa kationsko aktivne snovi znana ali kadar je bilo prej dognana, če je njegova sestava izražena kot odstotek mase. Če je prisoten več kot eden kationsko aktivni material, se lahko uporabi približek povprečne relativne molekulske mase. Metoda ne velja, če so prisotni anionski in/ali amfoterični površinski agenti.

ISO 2871-2:2010(E)
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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 2871-2 was prepared by Technical Committee ISO/TC 91, Surface active agents.
This second edition cancels and replaces the first edition (ISO 2871-2:1990), of which it constitutes a minor
revision.
ISO 2871 consists of the following parts, under the general title Surface active agents — Detergents —
Determination of cationic-active matter content:
⎯ Part 1: High-molecular-mass cationic-active matter
⎯ Part 2: Cationic-active matter of low molecular mass (between 200 and 500)
INTERNATIONAL STANDARD ISO 2871-2:2010(E)

Surface active agents — Detergents — Determination of
cationic-active matter content —
Part 2:
Cationic-active matter of low molecular mass (between 200
and 500)
1 Scope
This part of ISO 2871 specifies a method for the determination of low-molecular-mass cationic-active
materials such as monoamines, amine oxides, quaternary ammonium compounds and alkylpyridinium salts
which have a main chain of 10 to 22 carbon atoms and not more than 6 other carbon atoms in the cation.
The method is also suitable for other cationic-active materials.
The method is applicable to solids or to aqueous solutions of the active material when the relative molecular
mass of the cationic-active matter is known or when it has been previously determined if its content is
expressed as a percentage by mass. If more than one type of cationic-active material is present, an estimate
of average relative molecular mass may be used.
The method is not applicable if anionic and/or amphoteric surface active agents are present.
