Ethanol as a blending component for gasoline - Determination of total dry residue (involatile material) - Gravimetric method

This European Standard specifies a procedure for the determination of dry residue in ethanol by desiccation method in the range 0,1 to 1 % m/V. The total dry residue or total dry matter includes all matter that is non-volatile under specified physical conditions.

Ethanol zur Verwendung als Blendkomponente in Ottokraftstoff - Bestimmung des gesamten Trockenrückstandes (nichtflüchtige Bestandteile) - Gravimetrisches Verfahren

Diese Europäische Norm legt ein Verfahren zur Bestimmung des gesamten Trockenrückstandes im Bereich
von 10 mg/100 ml bis 25 mg/100 ml fest. Die gravimetrische Bestimmung erfolgt durch Trocknung.
ANMERKUNG Das in einem Ringversuch [2] beschriebene Prüfverfahren wurde bis herab zu 3,5 mg/100 ml geprüft.
Dabei hat sich jedoch eine ungenügende Präzision ergeben.
WARNUNG - Die Anwendung dieses Dokuments kann den Einsatz gefährlicher Stoffe, Arbeitsgänge
und Geräte mit sich bringen. Diese Norm gibt nicht vor, alle mit ihrer Anwendung verbundenen
Sicherheitsprobleme anzusprechen. Der Anwender dieser Norm ist dafür verantwortlich, vorher
angemessene Maßnahmen zu ergreifen und die Anwendbarkeit einschränkender Vorschriften zu
ermitteln.

Ethanol comme constituant d'essence - Détermination de la residue totale (matérial involatil) - Méthode gravimetrique

La présente Norme européenne prescrit une méthode pour la mesure de la teneur en résidu sec de l'éthanol,
dans un domaine allant de (10 à 25) mg/100 ml, le résidu étant obtenu par méthode gravimétrique
(dessiccation).
NOTE Au cours d’une étude interlaboratoires [2], la méthode décrite a été testée sur de plus faibles quantités, avec
un minimum de 3,5 mg/100 ml, mais la fidélité s’avère insuffisante à de tels niveaux.
AVERTISSEMENT — L'utilisation du présent document peut impliquer l'intervention de produits,
d'opérations et d'équipements à caractère dangereux. La présente norme européenne n'est pas
censée aborder tous les problèmes de sécurité concernés par son usage. Il est de la responsabilité de
l'utilisateur de consulter et d'établir des règles de sécurité et d'hygiène appropriées et de déterminer
l'applicabilité des restrictions réglementaires avant utilisation.
