FOREWORD
ISO (the International Organization for Standardization) is a worldwide federation
of national Standards institutes (ISO member bodies). The work of developing
International Standards is carried out through ISO technical committees. Every
member body interested in a subject for which a technical committee has been set
up 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.
Draft International Standards adopted by the technical committees are circulated
to the member bodies for approval before their acceptance as International
Standards by the ISO Council.
International Standard ISO 4796 was developed by Technical Committee
lSO/TC 48, Laboratoty glassware and related apparatus, and was circulated to
the member bodies in March 1976.
lt has been approved by the member bodies of the following countries :
Australia Germany Netherlands
Austria Hungary Romania
Belgium India South Africa, Rep. of
Canada Israel Spain
Chile . Italy Turkey
Czechoslovakia Korea, Rep. of United Kingdom
France Mexico U.S.S.R.
No member body expressed disapproval of the document.

- the outside rim or lip at the top of the neck shall
be so designed that, at the end of the pouring Operation,
the last drop is transferred to the receiving vessel and
does not run down the outside of the bottle. The precise

AVANT-PROPOS
L’ISO (Organisation internationale de normalisation) est une fédération mondiale
I’ISO). L‘élaboration
d’organismes nationaux de normalisation (comités membres de
des Normes internationales est confiée aux comités techniques de I’ISO. Chaque
comité membre intéressé par une étude a le droit de faire partiedu comité technique
correspondant. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec I‘ISO, participent également aux travaux.
Les projets de Normes internationales adoptés par les comités techniques sont
soumis aux comités membres pour approbation, avant leur acceptation comme
Normes internationales par le Conseil de I‘ISO.
La Norme internationale IS0 4796 a été élaborée par le comité technique
ISO/TC 48, Verrerie de laboratoire et appareils connexes, et a été soumise aux
comités membres en mars 1976.
Le5 comités membres des pays suivants l‘ont approuvée :
Afrique du Sud, Rép. d’ Corée, Rep. de Mexique
Allemagne Espagne Pays-Bas
Roumanie
Australie France
Autriche Hongrie Royaume-Uni

Deux caractéristiques influent principalement sur la sécurité ratoire sont données dans le tableau et sur la figure ci-après.
en cours de manipulation :
- le col et la partie supérieure du flacon doivent être
coi a bouchon visse 01 conique (rodé)
conçus de façon que l'air ne puisse être retenu dans
l'épaulement lorsque le flacon, rempli à sa capacité
nominale, est renversé pour assurer l'écoulement, et
cela afin d'éviter les risques de «glouglou» et d'écla-
boussure des liquides. Cette partie du flacon peut être
judicieusement réalisée en donnant une forme conique
à sa partie supérieure;
- le bord, ou le rebord extérieur, au sommet du col
doit être conçu de façon qu'à la fin de l'écoulement,
la dernière goutte soit recueillie dans le récipient
récepteur et sans qu'elle coule le long de la paroi exté-
rieure du flacon. La forme précise du rebord dépendra,
dans une certaine mesure, du mode de fabrication et
sa forme générale peut seulement être indiquée.
1 OBJET ET DOMAINE D'APPLICATION
La présente Norme internationale spécifie les détails d'une
