Metallic coatings - Porosity tests - Humid sulfur (flowers of sulfur) test (ISO 12687:1996)

Specifies a method of revealing discontinuities and porosity in metallic coatings, where they penetrate the coating layer down to a substrate. Especially useful for coatings consisting of single or combined layers.

Metallische Überzüge - Prüfung der Porosität - Naß-Schwefelverfahren (mit Schwefelblüte) (ISO 12687: 1996)

Diese internationale Norm legt ein Verfahren zum Sichtbarmachen von Fehlstellen und Porosität in metallischen Überzügen fest, bei denen sie die Überzugsschicht oder Zwischenschichten bis auf den aus Silber, Kupfer oder einer Kupferlegierung bestehenden Grundwerkstoff durchdringen. Dieses Verfahren ist besonders nützlich für Überzüge, die aus einer einzigen oder kombinierten Schicht eines Überzugs bestehen, der nur unwesentlich in einer aus redurziertem Schwefel bestehenden Atmosphäre anläuft, wie z.B. Gold, Nickel, Zinn-Blei-Palladium und deren Legierungen.

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, governmental
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 International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard IS0 12687 was prepared by Technical Committee
lSO/TC 107, Metallic and other inorganic coatings, Subcommittee SC 7,
Corrosion tests.
Annexes A and B of this International Standard are for information only.

INTERNATIONAL STANDARD @ IS0
Humid sulfur (flowers
Metallic coatings - Porosity tests -
of sulfur) test
1 Scope
This International Standard specifies a method of revealing discontinuities and porosity in metallic coatings, where
they penetrate the coating layer or layers down to a silver, copper or copper-alloy substrate.
This method is especially useful for coatings consisting of single or combined layers of any coating that does not
significantly tarnish in a reduced-sulfur atmosphere, such as gold, nickel, tin, tin-lead palladium and their alloys.
This test method is designed to show whether or not the coating meets the requirement concerning an acceptable
porosity level specified by the user. The value specified is usually determined by user’s experience to be
acceptable for the intended application.
Recent reviews of porosity testing and test methods can be found in the literature [IL 121. An IS0 general guide to
porosity tests for metallic and other inorganic coatings is available as IS0 10308:1995, Metallic coatings - Review
of porosity tests.
