Published By Publication Date Number of Pages
ISO 2021-05 14
]]> This document specifies spectroscopic ellipsometry for the determination of optical properties (refractive index n and extinction coefficient k) and the optical classification of different types of amorphous carbon films within the n–k plane.

It is applicable to amorphous carbon films deposited by ionized evaporation, sputtering, arc deposition, plasma-assisted chemical vapour deposition, hot filament techniques and others.

It does not apply to carbon films modified with metals or silicon, amorphous carbon films that have a gradient of composition/property in the thickness, paints and varnishes.

Published By Publication Date Number of Pages
ISO 2017-09 18
]]> ISO 20523:2017 specifies classification, designations and short names for carbon based films. These are films in which carbon is the predominant constituent part and which are deposited by physical vapour deposition (PVD) or chemical vapour deposition (CVD) process. This includes amorphous carbon-based films, also called diamond-like carbon films (DLC), as well as CVD diamond films, graphite and polymer-like films.

ISO 20523:2017 is applicable to those films which are produced on an industrial scale. Additional carbon based films are under development.

ISO 20523:2017 refers to the material of carbon based films. It does not refer to the entire coating that can consist of a main functional layer with additional layers below or on top.

A layer can change in composition and/or material property over its thickness. Such layers are called gradient layers. The definitions in this document refer to non-gradient layers.

A carbon based film can include other elements like hydrogen, metal elements or others. Metal constituents can be included as metal carbides. Films with additional elements are only covered by this document if carbon is the predominant constituent part. Carbon incorporated as carbide, as can be present in metal-containing amorphous carbon films (a-C:Me, a-C:H:Me), does not count to this amount.

ISO 20523:2017 does not apply to the class of carbon materials such as fullerenes, carbon nanotubes and graphene.

Published By Publication Date Number of Pages
ISO 2017-05 18
]]> ISO 20267:2017 specifies a method for measuring the interfacial toughness of thermal spray ceramic coatings at room temperature based on an indentation method. The interfacial toughness is calculated from the mean length of cracks emanating from the corners of the impression induced by a Vickers hardness tester, and it is intended for use with ceramic coatings with a single layer or multilayers. The test procedures proposed in this document are intended for use in an ambient environment.

ISO 20267:2017 is recommended for thermal spray ceramic coatings such as thermal barrier coatings, wear resistant coatings and electrical insulating coatings.

Published By Publication Date Number of Pages
ISO 1999-12 16
]]> This International Standard specifies requirements for epoxy powders for use in preparing fusion-bonded epoxycoated

steel reinforcing bar, wire and welded fabric. This International Standard also includes requirements for

sealing material used to repair damaged areas and cut ends on reinforcing steel.

This International Standard defines a flexible (type A) coating and a nonflexible (type B) coating. The adhesion and

moisture resistance of fusion-bonded epoxy powder coatings can be enhanced by certain formulation designs.

These coating enhancements typically result in a reduction of the coating's flexibility.

Ziel dieser Praxis ist es, viele der bekannten Variablen so zu definieren und zu steuern, dass gültige Vergleiche der Kontakteigenschaften von Materialien möglich sind. Diese Prüfung kann je nach dem geprüften Prozess lokal zerstörend sein.*Inhaltsverzeichnis
