Methods of testing cement - Part 3: Determination of setting times and soundness
This European Standard specifies the methods for determining standard consistence, setting times and soundness of cements.
The method applies to common cements and to other cements and materials, the standards for which call up this method. It may not apply to other cement types that have, for example, a very short initial setting time. The method is used for assessing whether the setting time and soundness of a cement is in conformity with its specification.
This part of EN 196 describes the reference methods and allows the use of alternative procedures and equipment, as indicated in notes, provided that they have been calibrated against the reference methods. In the event of a dispute, only the reference equipment and procedures are used.
Prüfverfahren für Zement - Teil 3: Bestimmung der Erstarrungszeiten und der Raumbeständigkeit
Diese Europäische Norm legt die Verfahren zur Bestimmung der Normsteife, der Erstarrungszeiten und der Raumbeständigkeit von Zement fest.
Die Verfahren gelten für Normalzemente; ferner gelten sie für andere Zemente und Baustoffe, wenn in den entsprechenden Normen auf diese Verfahren verwiesen wird. Unter Umständen gelten die Verfahren nicht für Zementarten, bei denen beispielsweise der Erstarrungsbeginn sehr rasch einsetzt. Die Verfahren werden angewendet, um beurteilen zu können, ob Zemente die gestellten Anforderungen hinsichtlich der Erstarrungszeiten und der Raumbeständigkeit erfüllen.
Der vorliegende Teil von EN 196 beschreibt die Referenzverfahren; andere Verfahren und Geräte - sofern in Anmerkungen darauf hingewiesen ist - dürfen angewendet werden, wenn sie nachweislich zu den gleichen Prüfergebnissen führen wie die vorgeschriebenen Verfahren und Geräte. Im Streitfall sind die Referenzgeräte und die Referenzverfahren maßgebend.
Méthodes d'essai des ciments - Partie 3 : Détermination du temps de prise et de la stabilité
Cette norme européenne spécifie les méthodes permettant de déterminer la consistance normalisée, les temps de prise et la stabilité des ciments.
La méthode s’applique aux ciments courants et à d’autres ciments et matériaux, pour lesquels les normes prescrivent ces méthodes. Elle ne doit pas s’appliquer aux autres types de ciments, qui ont, par exemple, un temps de début de prise très court. La méthode est utilisée pour juger si le temps de prise et la stabilité d’un ciment sont conformes à sa spécification.
Cette partie de l'EN 196 décrit les méthodes de référence et, comme indiqué dans les notes, autorise l'utilisation de variantes pour les modes opératoires et l’équipement, à condition que ces variantes aient été étalonnées par rapport aux méthodes de référence. En cas de litige, on doit utiliser seulement l’équipement et les modes opératoires de référence.
Metode preskušanja cementa - 3. del: Določanje časa vezanja in prostorninske obstojnosti
Ta evropski standard določa metode za določanje standardne gostote, čase vezanja in prostorninske obstojnosti cementov.
Metoda se uporablja za običajne vrste cementa in druge vrste cementa in materialov, katerih standardi zahtevajo njeno uporabo. Ne uporablja se za druge vrste cementa, ki na primer vključujejo zelo kratek začetni čas vezanja. Ta metoda se uporablja za ocenjevanje, ali sta čas vezanja in prostorninska obstojnost cementa v skladu s svojo specifikacijo.
Ta del standarda EN 196 opisuje referenčne metode ter dovoljuje uporabo drugih postopkov in opreme, kot je navedeno v opombah, če so kalibrirani glede na referenčne metode. V primeru spora se uporabljajo le referenčna oprema in postopki.

1 Scope
This European Standard specifies the methods for determining standard consistence, setting times and
soundness of cements.
The method applies to common cements and to other cements and materials, the standards for which
call up this method. It may not apply to other cement types that have, for example, a very short initial
setting time. The method is used for assessing whether the setting time and soundness of a cement is in
conformity with its specification.
This part of EN 196 describes the reference methods and allows the use of alternative procedures and
equipment, as indicated in notes, provided that they have been calibrated against the reference
methods. In the event of a dispute, only the reference equipment and procedures are used.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.
EN 196-1, Methods of testing cement - Part 1: Determination of strength
3 Principles
Cement paste of standard consistence has a specified resistance to penetration by a standard plunger.
The water required for such a paste is determined by trial penetrations of pastes with different water
contents.
The setting time is determined by observing the penetration of a needle into cement paste of standard
consistence until it reaches a specified value.
The soundness is determined by observing the volume expansion of cement paste of standard
consistence as indicated by the relative movement of two needles.
4 Laboratory, equipment and materials
4.1 Laboratory
The laboratory in which specimens are prepared and tested shall be maintained at a temperature of
(20 ± 2) °C and a relative humidity of not less than 50 %.
The temperature and relative humidity of the air in the laboratory and the temperature of the water in
the storage containers shall be recorded at least once per day during testing.
Cement, water and apparatus used to make and test specimens shall be at a temperature of (20 ± 2) °C.
NOTE See Annex A for storage conditions to be applied when testing setting times by alternative method.
Where temperature ranges are given, the target temperature at which the controls are set shall be the
middle value of the range.
4.2 Equipment and materials
The tolerances shown in Figures 1 and 2 are important for correct operation of the equipment in the
testing procedure. When regular control measurements show that the tolerances are not met, the
equipment shall be rejected, adjusted or repaired. Records of control measurements shall be kept.
Acceptance measurements on new equipment shall cover mass, volume, and dimensions to the extent
that these are indicated in this document paying particular attention to those critical dimensions for
which tolerances are specified.
In those cases where the material of the equipment can influence the results, the material is specified
and shall be used.
The approximate dimensions shown in the figures are provided as guidance to equipment
manufacturers or operators. Dimensions which include tolerances are obligatory.
4.2.1 Balance, capable of weighing to an accuracy of ± 1 g.
4.2.2 Graduated cylinder or burette, capable of dispensing to an accuracy of ± 1 ml.
4.2.3 Mixer, conforming to EN 196-1.
NOTE A more homogeneous paste is produced at the lower limit of tolerance for the clearance between the
blade and the bowl.
4.2.4 Water, distilled or deionized water shall be used for making the specimens.
Drinking water may be used for storing and boiling specimens.
4.2.5 Timer, capable of measuring to an accuracy of ± 1 s.
