Foreword
ISO (the International Organization for Standardization )is a worldwide
federation of national standards bodies(SO member bodies). The work of
preparing International Standards is normally carried out through SO
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 SO, also take part in the work. So
collaborates closely with the International Electrotechnical Commission
(EC)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 Committe
ISO/C 35 Paints and varnishes. Subcommittee 9. Genera fest methods
for paints and varnishes
It cancels and replaces ISO 6270: 1980, of which it constitutes a minor
technical revision
It differs from SO 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 rathe
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
