Emails und Emaillierungen - Bestimmung der Beständigkeit gegen Schwefelsäure bei Raumtemperatur (ISO 8290:1998)

Diese Internationale Norm legt ein Verfahren zur Bestimmung der Beständigkeit emaillierter Gegenstände gegen Schwefelsäure bei Raumtemperatur und außerdem ein Verfahren zur Einteilung der Ergebnisse in Klassen fest. Die Norm ist insbesondere für die Prüfung emaillierter Gegenstände, die mit schwefelsäurehaltigen Verbrennungserzeugnissen in Berührung kommen, bestimmt. Die Norm ist nicht anwendbar für Emaillierungen, die mit schwachen oder mit heißen starken Säuren in Berührung kommen, sowie für emaillierte Gegenstände, die in der chemischen Industrie angewendet werden.

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 8290 was prepared by Technical Committee ISO/TC 107, Metal and other inorganic
coatings, subcommittee SC 6, Vitreous and porcelain enamels.
This second edition cancels and replaces the first edition (ISO 8290:1987) which has been technically revised.
Annex A of this International Standard is for information only.

Vitreous and porcelain enamels — Determination of
resistance to sulfuric acid at room temperature
1 Scope
This International Standard specifies a method of test for the determination of resistance to sulfuric acid, at room
temperature, of vitreous and porcelain enamelled articles, and also specifies a method for classifying the results.
It is particularly intended for the testing of vitreous and porcelain enamelled articles that come into contact with
products of combustion containing sulfuric acid.
It is not applicable to vitreous and porcelain enamels that come into contact with weak acids or hot strong acids or to
vitreous and porcelain enamelled articles for use in the chemical industry.
NOTES
1  For testing the resistance to citric acid of vitreous and porcelain enamels at room temperature, see ISO 2722.
2  For testing the resistance to boiling citric acid, see ISO 2742.
3  For testing the resistance to condensing hydrochloric acid vapour of vitreous and porcelain enamelled surfaces of containers
and equipment used in the chemical industry, see ISO 2743.

3 Principle
A part of the surface of a test specimen is exposed under defined conditions to sulfuric acid solution.
The resistance of the enamelled surface is assessed using methods based on appearance and cleanability.
4 Reagents
During the determination, unless otherwise stated, use only reagents of recognized analytical grade and only
distilled water, or water of equivalent purity (grade 3 water complying with ISO 3696).
