Bitumen and bituminous binders - Determination of the pH value of bitumen emulsions
This European Standard specifies a method for measuring the pH value of bitumen emulsions. It is applicable to anionic, cationic and nonionic bitumen emulsions. NOTE: In certain circumstances, the pH value may 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).
Bitumen und bitumenhaltige Bindemittel - Bestimmung des pH-Wertes von Bitumenemulsionen
Diese Europäische Norm legt ein Verfahren zur Bestimmung des pH-Wertes von Bitumenemulsionen fest. Es ist auf anionische, kationische und nichtionische Bitumenemulsionen anwendbar. ANMERKUNG: Unser bestimmten Umständen kann der pH-Wert einen Hinweis auf den ionischen Charakter einer Bitumenemulsion geben. Dieser Hinweis sollte aber durch eine Teilchenpolaritätsprüfung nach EN 1430 bestätigt werden. (1)
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 cationiques, anioniques et non-ioniques.
NOTE Dans certains cas, la valeur du pH peut fournir une indication sur le caractere ionique de l'émulsion de bitume. Toutefois, il convient de confirmer cette indication en effectuant un essai afin de déterminer la polarité des particules conformément a l'EN 1430 [1].
AVERTISSEMENT L'utilisation de la présente Norme européenne implique l'intervention de produits, d'opérations et d'équipements a caractere dangereux. La présente Norme européenne n'a pas la prétention d'aborder tous les problemes de sécurité concernés par son usage. Il est de la responsabilité de l'utilisateur de consulter et d'établir des regles de sécurité et d'hygiene appropriées et de déterminer l'applicabilité des restrictions réglementaires avant utilisation.
