Foreword
ISO (the International Organization for Standardization) is a worldwide fed-
eration 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 rep-
resented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO col-
laborates closely with the International Electrotechnical Commission (IEC)
on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are cir-
culated 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 7783-1 was prepared by Technical Committee
ISO/TC 35, Paints and varnishes, Subcommittee SC 9, General test meth-
ods for paints and varnishes.
L ’ISO 7783 consists of the following Parts, under the general title Paints
and varnishes - De termina tjon of wa ter-vapour transmission rate:
- Part 7: Dish me thod for free films
- Part 2: Method for films supported by a porous Substrate

Introduction
This part of ISO 7783 is one sf a series of Standards dealing with the
sampling and testing of paints, varnishes and related products. lt describes
a method for determining the water-vapour transmission rate of an unsup-
ported paint film. ISO 7783-21) describes a method for determining the
water-vapour transmission rate of a paint film supported by a porous sub-
strate.
Water-vapour transmission rate is most commonly of interest when the
coating is applied to a porous Substrate. Depending on the conditions of
use, water vapour may be expected to pass in either direction through the
coating.
The procedure is commonly used to compare the transmission rates of
two or more different paint films and not to obtain absolute results. In the
latter case, it may be preferable to carry out the determination on a coated
test piece of the appropriate permeable Substrate. The procedure for carry-
ing out that determination forms the subject of ISO 7783-2.
