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 6270-1 was prepared by Technical Committee
ISO/TC 35, Paints and varnishes, Subcommittee 9, General test methods
for paints and varnishes.
It cancels and replaces ISO 6270:1980, of which it constitutes a minor
technical revision.
It differs from ISO 6270:1980 in that the angle of the panels to the
horizontal has been changed from (15 ± 5)° to (60 ± 5)° and the
temperature of the air below the panels is maintained at (38 ± 2) °C rather
than at that of the water itself. Work has shown that the results do not differ
substantially between the two sets of conditions.
At the date of publication, ISO 6270 consisted of only one part, under the
general title Paints and varnishes – Determination of resistance to
humidity:
– Part 1: Continuous condensation
Other parts will be added at a later date. One of these parts will be
ISO 11503:1995, Paints and varnishes – Determination of resistance to
humidity (intermittent condensation), which will be renumbered into this
series.
Annex A forms an integral part of this part of ISO 6270.

INTERNATIONAL STANDARD  ISO ISO 6270-1:1998(E)
Paints and varnishes — Determination of resistance to humidity —
Part 1:
Continuous condensation
1 Scope
This part of ISO 6270 is one of a series of standards dealing with the sampling and testing of paints, varnishes and
related products.
It specifies a method for determining the resistance of paint films, paints systems and related products to conditions
of high humidity in accordance with the requirements of coating or product specifications.
The method is applicable to coatings both on porous substrates such as wood, plaster and plasterboard and on
non-porous substrates such as metal. It provides an indication of the performance likely to be obtained under
severe conditions of exposure where continuous condensation occurs on the surface.
The procedure may reveal failures of the coating (including blistering, staining, softening, wrinkling and
embrittlement) and deterioration of the substrate.
