Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International
Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 6556 was prepared by Technical Committee ISO/TC 48, Laboratory equipment, and by Technical
Committee CEN/TC 332, Laboratory equipment in collaboration.
This second edition cancels and replaces the first edition (ISO 6556:1981), which has been technically revised
to incorporate the following modifications.
a) Filter flasks of cylindrical shape with capacities of 3 l to 20 l have been added.
b) Two series of filter flasks have been introduced to meet market needs.
c) The glass material for filter flasks has been limited to borosilicate glass 3.3.
d) A requirement for thermal shock endurance of filter flasks has been added.
e) The dimensions and figures have been updated to the state of manufacturing.

Avant-propos
L’ISO (Organisation internationale de normalisation) est une fédération mondiale d’organismes nationaux de
normalisation (comités membres de l’ISO). L’élaboration des Normes internationales est en général confiée aux
comités techniques de l’ISO. Chaque comité membre intéressé par une étude a le droit de faire partie du comité
technique créé à cet effet. Les organisations internationales, gouvernementales et non gouvernementales,
en liaison avec l’ISO participent également aux travaux. L’ISO collabore étroitement avec la Commission
électrotechnique internationale (CEI) en ce qui concerne la normalisation électrotechnique.
Les Normes internationales sont rédigées conformément aux règles données dans les Directives ISO/CEI, Partie 2.
La tâche principale des comités techniques est d’élaborer les Normes internationales. Les projets de Normes
internationales adoptés par les comités techniques sont soumis aux comités membres pour vote. Leur publication
comme Normes internationales requiert l’approbation de 75 % au moins des comités membres votants.
L’attention est appelée sur le fait que certains des éléments du présent document peuvent faire l’objet de droits
de propriété intellectuelle ou de droits analogues. L’ISO ne saurait être tenue pour responsable de ne pas avoir
identifié de tels droits de propriété et averti de leur existence.
L’ISO 6556 a été élaborée par le comité technique ISO/TC 48, Équipement de laboratoire.
Cette deuxième édition annule et remplace la première édition (ISO 6556:1981), qui a fait l’objet d’une révision
technique afin d’inclure les modifications suivantes.
a) Ajout des fioles à filtrer de forme cylindrique ayant une capacité de 3 l à 20 l.
b) Ajout de deux séries de fioles à filtrer afin de répondre aux besoins du marché.
c) Utilisation exclusive du verre borosilicaté 3.3 pour la fabrication des fioles à filtrer.
d) Ajout d’une exigence relative à l’endurance au choc thermique des fioles à filtrer.
e) Mise à jour des dimensions et des figures en fonction des procédés actuels de fabrication.
