Fat and oil derivates - Fatty acid methyl ester (FAME) - Determination of acid value

This document specifies a titrimetric method for the determination of acid value in light coloured Fatty Acid Methyl Esters, hereinafter referred as FAME.
It allows the determination of acid value within a range of 0,10 mg KOH/g to 1,00 mg KOH/g.
NOTE 1 For the purposes of this document, the terms "% (m/m)" and "% (V/V)" are used to represent respectively the mass fraction and the volume fraction.
NOTE 2 For oils and fats the determination of acid value is specified in EN ISO 660 [1].
WARNING - The use of this document can involve hazardous materials, operations and equipment. This document does not purport to address all of the safety problems associated with its use. It is the responsibility of users of this document to take appropriate measures to ensure the safety and health of personnel prior to the application of the document, and to determine the applicability of any other restrictions for this purpose.

Erzeugnisse aus pflanzlichen und tierischen Fetten und Ölen - Fettsäure-Methylester (FAME) - Bestimmung der Säurezahl

Dieses Dokument legt ein titrimetrisches Verfahren zur Bestimmung der Säurezahl von schwach gefärbten Fettsäure-Methylestern, nachstehend als FAME bezeichnet, fest.
Es ermöglicht die Bestimmung der Säurezahl im Bereich von 0,10 mg KOH/g bis 1,00 mg KOH/g.
ANMERKUNG 1   Für die Zwecke dieses Dokuments wird zur Angabe des Massenanteils einer Substanz der Ausdruck „% (m/m)“ und für den Volumenanteil einer Substanz der Ausdruck „% (V/V)“ verwendet.
ANMERKUNG 2   Für alle Öle und Fette ist die Bestimmung der Säurezahl in EN ISO 660 [1] festgelegt.
WARNUNG — Die Anwendung dieses Dokuments kann die Anwendung gefährlicher Stoffe, Arbeits¬gänge und Geräte mit sich bringen. Dieses Dokument beansprucht nicht, alle damit verbundenen Sicherheitsprobleme zu behandeln. Es liegt in der Verantwortung des Anwenders dieses Dokuments, vor der Anwendung dieses Dokuments geeignete Maßnahmen für die Sicherheit und den Gesund¬heitsschutz des Personals zu ergreifen, und die Geltung weiterer diesbezüglicher Auflagen zu prüfen.

Produits dérivés des corps gras - Esters méthyliques d'acides gras (EMAG) - Détermination de l'indice d'acide

Le présent document spécifie une méthode titrimétrique pour la détermination de l’indice d’acide des esters méthyliques d’acides gras légèrement colorés, désignés dans le présent document par le terme EMAG.
Il permet la détermination de l’indice d’acide dans une plage de concentrations comprise entre 0,10 mg de KOH/g et 1,00 mg de KOH/g.
NOTE 1 Pour les besoins du présent document, les termes « % (m/m) » et « % (V/V) » sont respectivement utilisés pour représenter la fraction massique et la fraction volumique.
NOTE 2 Pour les corps gras, la détermination de l'indice d'acide est spécifiée dans l’EN ISO 660 [1].
AVERTISSEMENT - L’utilisation du présent document peut impliquer l’utilisation de produits et la mise en oeuvre de modes opératoires et d’appareillages à caractère dangereux. Le présent document n’a pas pour but d’aborder tous les problèmes de sécurité liés à son utilisation. Il est de la responsabilité des utilisateurs de ce document de prendre les mesures appropriées pour assurer la sécurité et préserver la santé du personnel avant son application, et pour déterminer l’applicabilité de toutes autres restrictions à cette fin.
