Perkenalan
ISO (Organisasi Internasional untuk Standardisasi) adalah aliansi global badan standar nasional (badan anggota ISO). Pengembangan standar internasional biasanya dilakukan melalui komite teknis ISO. Setiap lembaga anggota yang tertarik pada suatu mata pelajaran yang telah dibentuk komite teknisnya berhak untuk diwakili dalam komite tersebut. Governmental and non-governmental international organizations liaising with standardization organizations are also involved in this work. ISO bekerja sama dengan Komisi Elektroteknik Internasional (IEC) tentang segala hal standardisasi kelistrikan.

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” kekerasan) 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.

1 Jangkauan
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.
