Bitumen and bituminous binders - Determination of the pH value of bituminous emulsions

This European Standard specifies a method for measuring the pH value of bituminous emulsions.
It is applicable to anionic, cationic and non-ionic bitumen emulsions.
NOTE   In certain circumstances, the pH value can provide an indication of the ionic character of a bitumen emulsion. However, this indication should be confirmed by a particle polarity test conforming to EN 1430 [1].
WARNING — The use of this standard can involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Bitumen und bitumenhaltige Bindemittel - Bestimmung des pH-Wertes von Bitumenemulsionen

Diese Europäische Norm legt ein Verfahren zur Bestimmung des pH-Wertes von Bitumenemulsionen fest.
Sie ist auf anionische, kationische Bitumenemulsionen und Bitumenemulsionen, die mit Hilfe von nichtionischen
Tensiden vorbereitet wurden, anwendbar.
ANMERKUNG Unter bestimmten Umständen kann der pH-Wert einen Hinweis auf den Ionencharakter einer Bitumenemulsion
geben. Dieser Hinweis sollte jedoch durch eine Prüfung der Teilchenpolarität nach EN 1430 [1] bestätigt werden.
WARNUNG — Die Anwendung dieser Norm kann den Umgang mit gefährlichen Substanzen und Ausrüstungsteilen
und die Ausführung gefährlicher Arbeitsgänge einschließen. Diese Norm erhebt nicht
den Anspruch, alle mit ihrer Anwendung verbundenen Sicherheitsprobleme anzusprechen. Es liegt in
der Verantwortung des Anwenders dieser Norm, geeignete Verhaltensregeln für den Arbeits- und
Gesundheitsschutz festzulegen und vor der Anwendung zu klären, ob einschränkende Vorschriften zu
berücksichtigen sind.

Bitumes et liants bitumineux - Détermination du pH des émulsions de bitume

La présente Norme européenne prescrit une méthode pour la détermination du pH des émulsions de bitume.
Elle est applicable aux émulsions de bitume anioniques, cationiques et aux émulsions de bitume préparées à
l’aide de surfactants non-ioniques.
NOTE Dans certains cas, la valeur du pH peut fournir une indication sur le caractère ionique de l’émulsion de bitume.
Toutefois, il convient de confirmer cette indication en effectuant un essai de détermination de la polarité des particules
conformément à l’EN 1430 [1].
AVERTISSEMENT — L'utilisation de la présente Norme européenne implique l'intervention de
produits, d'opérations et d'équipements à caractère dangereux. La présente Norme européenne n'a
pas la prétention d'aborder tous les problèmes de sécurité associés à 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.
