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

This document specifies a method for measuring the pH value of bituminous emulsions.
It is applicable to anionic, cationic bituminous emulsions and bituminous emulsions prepared by means of non-ionic surfactant.
In certain circumstances, the pH value can provide an indication of the ionic character of a bituminous emulsion. However, this indication should be confirmed by a particle polarity test conforming to EN 1430 [1].
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 the user of this document to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.

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

Dieses Dokument legt ein Verfahren zur Bestimmung des pH Wertes von Bitumenemulsionen fest.
Es ist auf anionische, kationische Bitumenemulsionen und Bitumenemulsionen, die mit Hilfe von nicht-ionischen Tensiden vorbereitet wurden, anwendbar.
Unter bestimmten Umständen kann der pH Wert einen Hinweis auf den Ionencharakter einer Bitumen-emulsion geben. Dieser Hinweis sollte jedoch durch eine Prüfung der Teilchenpolarität nach EN 1430 [1] bestätigt werden.
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 Gesundheitsschutz¬maßnahmen vorzusehen und im Vorfeld die Anwendbarkeit von einschränkenden Vorschriften zu klären.

Bitumes et liants bitumineux - Détermination du pH des émulsions bitumineuses

Ce document spécifie une méthode pour la détermination du pH des émulsions bitumineuses.
Il est applicable aux émulsions bitumineuses anioniques, cationiques et aux émulsions bitumineuses préparées à l’aide de surfactants non-ioniques.
Dans certains cas, la valeur du pH peut fournir une indication sur le caractère ionique de l’émulsion bitumineuse. 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 ce document implique l'intervention de produits, d'opérations et d'équipements à caractère dangereux. Le présent document n'est pas censé aborder tous les problèmes de sécurité concernés par son usage. Il est de la responsabilité de son utilisateur d'établir des règles d'hygiène et de sécurité appropriées et de déterminer l'applicabilité des restrictions réglementaires avant utilisation.

Bitumen in bitumenska veziva - Določevanje pH vrednosti bitumenskih emulzij

Ta dokument določa metodo za merjenje pH vrednosti bitumenskih emulzij.
Uporablja se za anionske in kationske bitumenske emulzije ter bitumenske emulzije, pripravljene z neionsko površinsko aktivno snovjo.
V določenih okoliščinah se lahko pH vrednost uporablja kot pokazatelj ionskega značaja bitumenske emulzije. Vendar ta podatek naj se potrdi s preskusom polarnosti delcev v skladu s standardom EN 1430 [1].
OPOZORILO: Pri uporabi tega dokumenta so lahko prisotni nevarni materiali, postopki in oprema. Ta dokument ne obravnava vseh varnostnih težav, ki se navezujejo na njegovo uporabo. Za vzpostavitev ustreznih varnostnih in zdravstvenih praks ter za določitev uporabnosti regulativnih omejitev pred uporabo je odgovoren uporabnik tega dokumenta.
