Paints and varnishes - Buchholz indentation test (ISO 2815:1973)

This standard specifies a method for carrying out an indentation test on a single coating or multicoat system of paint, varnish or related product, using a specified instrument (Buchholz).

Beschichtungsstoffe - Eindruckversuch nach Buchholz (ISO 2815:1973)

Diese Internationale Norm legt ein Verfahren fest zur Durchführung eines Eindruckversuchs an einer einzelnen Schicht oder einem Mehrschichtsystem aus Lacken, Anstrichstoffen oder ähnlichen Beschichtungsstoffen mit einem bestimmten Gerät (nach Buchholz). Die Eindrucklänge, die ein Eindruckkörper von bestimmter Größe und Form unter bestimmten Prüfbedingungen in der Beschichtung hinterläßt, ist Bestimmungsgröße für die bleibende Verformung der Beschichtung. Das Prüfergebnis wird als Funktion des Kehrwertes der Eindrucklänge angegeben.

FOREWORD
IS0 (the International Organization for Standardization) is a worldwide federation
of national standards institutes (IS0 Member Bodies). The work of developing
International Standards is carried out through IS0 Technical Committees. Every
Member Body interested in a subject for which a Technical Committee has been set
up 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.
Draft International Standards adopted by the Technical Committees are circulated
to the Member Bodies for approval before their acceptance as International
Standards by the IS0 Council.
International Standard IS0 2815 was drawn up by Technical Committee
lSO/TC 35,.Paints and varnishes, and circulated to the Member Bodies in May 1972.
It has been approved by the Member Bodies of the following countries :
Austria India South Africa, Rep. of
Canada Iran Sweden
Chile Israel Switzerland
Czechoslovakia Netherlands Turkey
Egypt, Arab Rep. of Poland United Kingdom
France Portugal U.S.S.R.
Germany Romania
No Member Body expressed disapproval of the document.
