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. Esch 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, govern-
mental 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.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an Inter-
national Standard requires approval by at least 75 % of the member
bodies casting a vote.
International Standard ISO 3402 was prepared by Technical Committee
ISO/TC 126, Tobacco and tobacco products.
This third edition cancels and replaces the second edition (ISO
3402:1978), which has been technically revised.

Avant-propos
L’ISO (Organisation internationale de normalisation) est une fédération
mondiale d‘organismes nationaux de normalisation (comités membres
de I’ISO). L‘élaboration des Normes internationales est en général
confiée aux comités techniques de I’ISO. Chaque comité membre inté-
ressé 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 I’ISO participent également aux tra-
vaux. L’ISO collabore étroitement avec la Commission électrotechnique
internationale (CEI) en ce qui concerne la normalisation électrotech-
nique.
Les projets de Normes internationales adoptés par les comités techni-
ques sont soumis aux comités membres pour vote. Leur publication
comme Normes internationales requiert l’approbation de 75 % au moins
des comités membres votants.
La Norme internationale IS0 3402 a été élaborée par le cornité techni-
que ISO/TC 126, Tabac et produits du tabac.
Cette troisième édition annule et remplace la deuxième édition (IS0
3402:1978), qui a fait l‘objet d’une révision technique.

I n t rod u ct i on
En 1988 et 1989, des membres des groupes fumée^^ et ((Technologie»
du Centre de coopération pour les recherches scientifiques relatives au
tabac (CORESTA), dans le cadre de groupes de travail constitues à cet
effet, ont conduit des études relatives à la répétabilité et la reproduc-
tibilité des essais sur le tabac et les produits du tabac.
Afin de pouvoir comparer les résultats d‘essais entre différents labora-
toires, il s’est avéré nécessaire de spécifier une seule atmosphere pour
le conditionnement et la conduite des essais, plutôt que de permettre
l’emploi d’une des trois possibilités préconisées dans les deux éditions
précédentes de la présente Norme internationale.
II a également pu être établi que les tolérances préalablement préconi-
sées pour l’humidité relative de l’atmosphère d’essai, étaient difficiles
à maintenir dans la pratique.
Ces études ont abouti à la publication de la méthode recommandée
CORESTA no 21.
