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

This European Standard specifies a procedure for the determination of dry residue in ethanol by gravimetric (desiccation) method in the range (10 to 25) mg/100 ml.
NOTE   In an interlaboratory study [2] the method described has been tested at levels down to 3,5 mg/100 ml, but the precision appeared to be insufficient at such low levels.
WARNING - Use of this document may involve hazardous equipment, materials and operations. This method does not purport to address to all of the safety problems associated with its use, but it is the responsibility of the user to search and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

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

Dieses Dokument legt ein gravimetrisches Verfahren zur Bestimmung des Trockenrückstandes in Ethanol im Bereich von 10 mg/100 ml bis 25 mg/100 ml fest.
ANMERKUNG   In einem Ringversuch [2] wurde das beschriebene Verfahren bis herab zu 3,5 mg/100 ml geprüft; dabei hat sich jedoch eine ungenügende Präzision ergeben.
WARNUNG - Die Anwendung dieses Dokuments kann die Anwendung gefährlicher Stoffe, Arbeitsgänge und Geräte mit sich bringen. Dieses Verfahren beansprucht nicht, alle damit verbundenen Sicherheitsprobleme zu behandeln. Es liegt in der Verantwortung des Anwenders dieses Dokuments, vor seiner Anwendung geeignete Maßnahmen für die Sicherheit und den Gesundheitsschutz des Personals zu ergreifen, und dafür Sorge zu tragen, dass behördliche und gesetzliche Anforderungen eingehalten werden.

Ethanol comme base de mélange à l'essence - Détermination du résidu sec (produits non volatils) - Méthode gravimétrique

Le présent document spécifie 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 des équipements, des matériaux et des opérations à caractère dangereux. Ce document ne prétend pas résoudre tous les problèmes de sécurité liés à son utilisation. Il est de la responsabilité de l'utilisateur de ce document de prendre les mesures appropriées pour assurer la sécurité et la santé du personnel avant l'application du document, et de respecter les restrictions légales et réglementaires à cet effet.

European foreword

This document (prEN 15691:2021) has been prepared by Technical Committee CEN/TC 19 “Gaseous

and liquid fuels, lubricants and related products of petroleum, synthetic and biological origin”, the

secretariat of which is held by NEN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 15691:2009.

It was originally prepared by CEN/TC 19’s Ethanol Task Force based on a regulated analysis method for

neutral alcohol [1].

In comparison with the previous edition, based on a re-evaluation of the interlaboratory study the

precision statement (Clause 10) has been replaced by the recalculated version. Following the same re-

evaluation the scope of the method (Clause 1) has
