Einführung
ISO (Internationale Standardisierungsorganisation) ist eine globale Allianz nationaler Normungsgremien (ISO-Mitgliedsorganisationen). Die Entwicklung internationaler Standards erfolgt in der Regel durch technische Komitees der ISO. Jede Mitgliedsinstitution, die an einem Thema interessiert ist, zu dem ein Fachausschuss eingerichtet wurde, hat das Recht, in diesem Ausschuss vertreten zu sein. Governmental and non-governmental international organizations liaising with standardization organizations are also involved in this work. ISO arbeitet eng mit der International Electrotechnical Commission zusammen (IEC) in allen Fragen der elektrischen Normung.

The procedures used to develop this document as well as those used for further maintenance are described in ISO/IEC Directive Part 1. Insbesondere, attention should be paid to the different approval criteria required for different types of ISO files. This document has been drafted in accordance with the editorial rules of ISO/IEC Directive Part 2 (siehe iso.org/directives).

The third edition cancels and replaces the second edition (ISO 15184:2012), which was a minor revision. The main changes from the previous version are as follows:

— In 5.1, the force of the instrument on the painted surface has been corrected to (7,35 ± 0,15) N;

– In 8.6, according to the protocol, the minimum pencil hardness that can also be tested to determine that cohesion does not break (so-called “overcut” Härte) has been removed so as not to confuse with those standards that describe the test method;

-The text has been edited and revised and the normative references updated.

ISO 15184-2020 “Farb- und Lackstiftmethode zur Bestimmung der Lackfilmhärte”

1 Reichweite
This document specifies a method for determining the hardness of a film by pushing a pencil of known hardness onto it.

The test can be performed on a single coating of paint, varnish or related products, or on the upper layer of a multi-coating system.

It has not been found that this rapid test can be used to compare the pencil hardness of different coatings. It is more suitable for providing relative ratings for a range of coated panels that exhibit significant differences in pencil hardness.

This method is only applicable to smooth surfaces.
