Diese Norm spezifiziert zwei Verfahren zur Bestimmung der Permeabilität von Elastomeren für flüchtige Flüssigkeiten durch Diffusion an die freie Atmosphäre, wobei die Durchlässigkeitsrate gemessen wird. Die Verfahren sind nur bei Elastomerplatten oder beschichteten Geweben mit einer Dicke zwischen 0,2 mm und 3,0 mm anwendbar. Sie sind auf Durchlässigkeitsraten von 0,1 g m2 h beschränkt.

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.
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.
International Standard ISO 6179 was prepared by Technical Committee
ISO/TC 45, Rubber and rubber products, Subcommittee SC 2, Physical
and degradation tests.
This third edition cancels and replaces the second edition (ISO 6179:1989),
which has been technically revised.

INTERNATIONAL STANDARD  ISO ISO 6179:1998(E)
Rubber, vulcanized or thermoplastic – Rubber sheets and rubber-coated
fabrics – Determination of transmission rate of volatile liquids (gravimetric
technique)
WARNING – Persons using this International Standard should be familiar with normal laboratory practice.
This standard does not purport to address all of the safety problems, if any, associated with its use. It is the
responsibility of the user to establish appropriate safety and health practices and to ensure compliance
with any national regulatory conditions.
1 Scope
This International Standard specifies two methods for determining, by measurement of the transmission rate, the
permeability of rubber to volatile liquids diffusing into open air.
lt is applicable only to materials in sheet form and to coated fabrics, having thicknesses of between 0,2 mm and
3,0 mm.

It is restricted to transmission rates of more than 0,1 g/m h.
The methods are particularly useful for comparing the relative transmission rates of one liquid through different
materials, or of several liquids through one material.
Method A, with refilling, is used when testing mixtures of liquids which give different transmission rates.
Method B, with no refilling, is used for a single-component liquid.
2 Normative references
The following standards contain provisions which, through reference in this text, constitute provisions of this
International Standard. At the time of publication, the editions indicated were valid. All standards are subject to
revision, and parties to agreements based on this International Standard are encouraged to investigate the
possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain
registers of currently valid International Standards.

3 Definition
For the purposes of this International Standard, the following definition applies.
3.1 transmission rate: The mass, in grams, of a volatile liquid which permeates through each square metre of a
rubber test sheet of a given thickness per hour under the test conditions specified in this standard.
4 Apparatus
4.1 Container assembly, consisting of a container for the test liquid, a suitable clamping device for the test piece
which does not impose a shearing force on the test piece, and a suitable support for the container, so that the test
piece and the test liquid are in contact at all times (with the apparatus inverted after filling), and such as to permit
free circulation of air across the surface of the test piece.
3 3
The container shall have a volume of 60 cm to 100 cm and an inlet valve for filling and refilling.
NOTE – For method B, an inlet valve is not necessary when introducing the test liquid before mounting the
test piece in place.
The mass of the container, the clamping ring, the test piece and 50 cm of the test liquid shall not exceed the
capacity of the balance (4.2).
The open end of the container and the hole in the clamping ring shall have a diameter such that approximately
10 cm of the surface of the test piece is ex
