Paints and varnishes - Determination of the pot-life of liquid systems - Preparation and conditioning of samples and guidelines for testing (ISO 9514:1992)

This international standard specifies a method, carried out under standard conditions, for preparing and storing a sample so that its pot-life may by assessed by measuring a particular property.

Lacke und Anstrichstoffe - Bestimmung der Topfzeit von flüssigen Systemen - Vorbereitung und Konditionierung von Proben und Richtlinien für die Prüfung (ISO 9514:1992)

Diese Internationale Norm gehört zu einer Reihe von Normen, welche die Probenahme und die Prüfung von Lacken, Anstrichstoffen und ähnlichen Beschichtungsstofen behandelt. Diese Internationale Norm legt ein Verfahren zur Vorbereitung und Lagerung einer Probe zur Bestimmung der Topfzeit fest. Die Topfzeit wird durch Messung einer speziellen Eigenschaft beurteilt.

Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
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, govern-
mental and non-governmental, in liaison with ISO, also take part in the
work. IS0 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 IS0 9514 was prepared by Technical Committee
ISO/TC 35, Paints and varnishes, Sub-Committee SC 9, General test
methods for paints and varnishes.
Annex A forms an integral part of this International Standard. Annexes
B and C are for information only.
