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.
NOTE In certain circumstances, the pH value can provide an indication of the ionic character of a bituminous emulsion when 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 anwendbar auf anionische, kationische Bitumenemulsionen und Bitumenemulsionen, die mit Hilfe von nicht ionischen Tensiden vorbereitet wurden.
ANMERKUNG Unter bestimmten Umständen kann der pH Wert einen Hinweis auf den Ionencharakter einer Bitumenemulsion geben, wenn dies durch eine Bestimmung der Teilchenpolarität nach EN 1430 [1] bestätigt wird.
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 Gesundheitsschutzmaßnahmen 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.
NOTE Dans certains cas, la valeur du pH peut fournir une indication sur le caractère ionique de l’émulsion bitumineuse dans la mesure où cette indication est confirmée par 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.

European foreword
This document (EN 12850:2022) has been prepared by Technical Committee CEN/TC 336 “Bituminous
binders”, the secretariat of which is held by AFNOR.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by January 2023, and conflicting national standards shall
be withdrawn at the latest by January 2023.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 12850:2009.
The main technical changes are:
— the number of required standard buffer solutions is at least two which bracket the expected pH value
to be measured (5.4 and Clause 8);
— the requirement to use certified buffer solutions and to follow manufacturer’s instructions for their
verification and storage conditions (5.4);
— the requirement to calibrate according to the manufacturer’s instructions for the used pH meter and
with the obligation to test pH = 7 and to frame the expected pH value (Clause 8);
— the requirement that the calibration temperatures are compliant with those indicated for each buffer
solution (Clause 8).
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
