Fat and oil derivatives - Fatty Acid Methyl Esters (FAME) - Determination of iodine value
This document specifies a titrimetric method for the determination of iodine value in Fatty Acid Methyl Esters, hereinafter referred as FAME.
The precision statement of this test method was determined in a Round Robin exercise with iodine values in the range 111 g iodine/100 g to 129 g iodine/100 g.
The test method is also applicable for lower iodine values, however, the precision statement is not established for iodine values below 111 g iodine/100 g.
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 Iodzahl
Dieses Dokument legt ein titrimetrisches Verfahren zur Bestimmung der Iodzahl von Fettsäure Methylestern, nachfolgend FAME genannt, fest.
Die Präzisionsangabe dieses Prüfverfahrens wurde in einem Ringversuch mit Iodzahlen im Bereich 111 g Iod/100 g bis 129 g Iod/100 g bestimmt.
Dieses Prüfverfahren gilt auch für niedrigere Iodzahlen, die Präzisionsangabe wird jedoch nicht für Iodzahlen unter 111 g Iod/100 g festgelegt.
WARNUNG — Die Anwendung dieses Dokumentes kann die Anwendung gefährlicher Stoffe, Arbeitsgänge und Geräte mit sich bringen. Dieses Dokument beansprucht nicht, alle damit verbundenen Sicherheitsprobleme zu behandeln. Es liegt in der Verantwortung des Anwenders dieses Dokuments, geeignete Sicherheits und Gesundheitsschutzmaßnahmen vorzusehen und im Vorfeld die Anwendbarkeit von einschränkenden Vorschriften zu klären.
Produits dérivés des corps gras - Esters méthyliques d'acides gras (EMAG) - Détermination de l'indice d'iode
Le présent document spécifie une méthode titrimétrique de détermination de l’indice d’iode des esters méthyliques d’acides gras, ci-après appelés EMAG.
Les mesures de fidélité de la présente méthode d’essai ont été déterminées lors d’un essai interlaboratoires avec des indices d’iode compris entre 111 g d’iode/100 g et 129 g d’iode/100 g.
La méthode d’essai s’applique également à des indices d’iode plus faibles ; cependant, les mesures de fidélité ne sont pas établies pour des indices d’iode inférieurs à 111 g d’iode/100 g.
AVERTISSEMENT — Le présent document peut impliquer l’utilisation de produits, de manipulations et d’équipements dangereux. Le présent document n’a pas pour objet d’aborder tous les problèmes de sécurité liés à son utilisation. Il incombe à l’utilisateur du présent document de prendre les mesures appropriées pour assurer l’hygiène et la sécurité du personnel avant l’application du présent document, et de déterminer l’applicabilité de toute autre restriction.
