ISO (Organisasi Internasional untuk Standardisasi) adalah federasi global badan standar nasional (badan anggota ISO). Pengembangan standar internasional biasanya dilakukan melalui komite teknis ISO. Each member group interested in a subject for which a technical committee has been established has the right to be represented on the Committee. Organisasi internasional, governments and non-governmental organizations in contact with ISO are also involved in this work. ISO bekerja sama dengan Komisi Elektroteknik Internasional (IEC) tentang segala hal standardisasi kelistrikan.

memperkenalkan
Fine ceramic films are used in a variety of applications, such as sensors, actuators or other micromechanical components; Display element; Memory element; Recording media; Optical components; Packaging film; As well as films and glass for buildings and vehicles. In the industrial application of fine ceramic films, wear resistance is an important index for evaluation. The wear resistance of fine ceramic films is greatly affected by the ambient humidity and the humidity history of the films. Fine ceramic films are also used in different humidity environments, requiring criteria for evaluating wear resistance and coefficient of friction over a wide humidity range. The standards published to date for wear resistance testing only assume a temperature environment of 23 °C dan kelembaban relatif 50%; The thickness of the film to be measured is also relatively large, several to 10μm. These test procedures are not suitable for evaluating the wear resistance of fine ceramic films with thickness up to approximately 1 µm and applied to electronic and optical devices because the wear resistance of small indentation loads is affected by relative humidity in the test environment, i.e. the mechanism used in the wear testing of fine ceramic films with small indentation loads is strongly affected by the relative humidity of the test environment. Karena itu, the wear test of fine ceramic films should be carried out under the specified relative humidity conditions. This document provides measurement methods that help to accurately evaluate the wear resistance of fine ceramic films in dry and high humidity environments, such films can be up to about 1 µm thick and deposited on thin substrates or organic polymer films. The purpose of this document is to promote industrial development through the rapid dissemination of these measurement methods.
