Fine ceramics (advanced ceramics, advanced technical ceramics) - Rockwell indentation test for evaluation of adhesion of ceramic coatings (ISO 26443:2023)

Fine ceramics (advanced ceramics, advanced technical ceramics) - Rockwell indentation test for evaluation of adhesion of ceramic coatings (ISO 26443:2023)

This document specifies a method for the qualitative evaluation of the adhesion of ceramic coatings up to 20 μm thick by indentation with a Rockwell diamond indenter. The formation of cracks after indentation can also reveal cohesive failure. The indentations are made with a Rockwell hardness test instrument.
The method described in this document can also be suitable for evaluating the adhesion of metallic coatings.
The test is not suitable for elastic coatings on hard substrates.

Hochleistungskeramik - Rockwell-Eindringprüfung zur Bewertung der Haftung von keramischen Schichten (ISO 26443:2023)

Dieses Dokument legt ein Verfahren zur qualitativen Bewertung der Haftung keramischer Schichten mit einer Dicke von bis zu 20 µm durch Erzeugung von Eindrücken mit einem Rockwell Diamant Eindringkörper fest. Die Bildung von Rissen am Eindruck kann auch ein Kohäsionsversagen erkennen lassen. Die Eindrücke werden mit einem Rockwell Härteprüfgerät erzeugt.
Das in diesem Dokument beschriebene Verfahren kann auch zur Bewertung der Haftung metallischer Schichten geeignet sein.
Diese Prüfung ist für elastische Schichten auf harten Grundwerkstoffen nicht geeignet.

Céramiques techniques - Évaluation de l'adhérence des revêtements céramiques par l'essai de pénétration Rockwell (ISO 26443:2023)

Le présent document spécifie une méthode permettant l’évaluation qualitative de l’adhérence de revêtements céramiques jusqu’à 20 μm d’épaisseur par indentation à l’aide d’un pénétrateur diamanté de Rockwell. La formation de fissures après l’indentation peut également révéler une rupture cohésive. Les indentations sont réalisées à l’aide d’un instrument d’essai de dureté Rockwell.
La méthode décrite dans le présent document peut également être adaptée à l’évaluation de l’adhérence de revêtements métalliques.
L’essai n’est pas adapté aux revêtements élastiques sur des substrats durs.

Fina keramika (sodobna keramika, sodobna tehnična keramika) - Preskus z vtiskanjem po Rockwellu za ovrednotenje sprijemnosti keramičnih prevlek (ISO 26443:2023)

Standard ISO 26443:2008 določa metodo za kakovostno ovrednotenje sprijemnosti keramičnih prevlek debeline do 20 µm z vtiskanjem z Rockwellovo diamantno preskusno konico. Nastanek razpok po vtiskanju lahko razkriva tudi kohezivno napako. Vtiskanje se izvede z Rockwellovim instrumentom za preskušanje trdote.
Opisana metoda je lahko primerna tudi za ovrednotenje sprijemnosti kovinskih prevlek.
Preskus ni primeren za elastične prevleke na trdih substratih.

SIST EN ISO 24370:2023

ISO 24370:2005 specifies a test method for determining the fracture toughness of monolithic ceramic materials at room temperature by the chevron-notched beam (CNB) method.
ISO 24370:2005 is applicable to monolithic ceramics and whisker- or particulate-reinforced ceramics that are regarded as macroscopically homogeneous. It is not applicable to continuous-fibre reinforced ceramic composites.
ISO 24370:2005 is usually applicable to ceramic materials with a fracture toughness less than about 12 megapascal(square root metre).

Fine ceramics (advanced ceramics, advanced technical ceramics) - Weibull statistics for strength data (ISO 20501:2019)
SIST EN ISO 20501:2023

This document covers the reporting of uniaxial strength data and the estimation of probability distribution parameters for advanced ceramics which fail in a brittle fashion. The failure strength of advanced ceramics is treated as a continuous random variable. Typically, a number of test specimens with well-defined geometry are brought to failure under well-defined isothermal loading conditions. The load at which each specimen fails is recorded. The resulting failure stresses are used to obtain parameter estimates associated with the underlying population distribution.
This document is restricted to the assumption that the distribution underlying the failure strengths is the two-parameter Weibull distribution with size scaling. Furthermore, this document is restricted to test specimens (tensile, flexural, pressurized ring, etc.) that are primarily subjected to uniaxial stress states. Subclauses 6.4 and 6.5 outline methods of correcting for bias errors in the estimated Weibull parameters, and to calculate confidence bounds on those estimates from data sets where all failures originate from a single flaw population (i.e. a single failure mode). In samples where failures originate from multiple independent flaw populations (e.g. competing failure modes), the methods outlined in 6.4 and 6.5 for bias correction and confidence bounds are not applicable.

This document describes procedures for determination of the compressive behaviour of ceramic matrix composite materials with continuous fibre reinforcement at room temperature. This method applies to all ceramic matrix composites with a continuous fibre reinforcement, uni-directional (1D), bi-directional (2D) and tri-directional (xD, with 2 < x < 3), tested along one principal axis of reinforcement or off axis conditions. This method also applies to carbon-fibre-reinforced carbon matrix composites (also known as carbon/carbon or C/C). Two cases of testing are distinguished: compression between platens and compression using grips.

Fine ceramics (advanced ceramics, advanced technical ceramics) - Methods for chemical analysis of aluminium nitride powders (ISO 21814:2019)
SIST EN ISO 21814:2023

This document specifies methods for the chemical analysis of fine aluminium nitride powders used as the raw material for fine ceramics.
This document stipulates the determination methods of the aluminium, total nitrogen, boron, calcium, copper, iron, magnesium, manganese, molybdenum, nickel, potassium, silicon, sodium, titanium, tungsten, vanadium, zinc, zirconium, carbon, chlorine, fluorine, and oxygen contents in aluminium nitride powders. The aluminium content is determined by using either an acid pressure decomposition-CyDTA-zinc back titration method or an acid digestion-inductively coupled plasma-optical emission spectrometry (ICP-OES) method. The total nitrogen content is determined by using an acid pressure decomposition-distillation separation-acidimetric titration method, a direct decomposition-distillation separation-acidimetric titration method, or an inert gas fusion-thermal conductivity method. The boron, calcium, copper, iron, magnesium, manganese, molybdenum, nickel, potassium, silicon, sodium, titanium, tungsten, vanadium and zinc contents are determined by using an acid digestion-ICP-OES method or an acid pressure decomposition-ICP-OES method. The sodium and potassium contents are determined via an acid pressure decomposition-flame emission method or an acid pressure decomposition-atomic absorption spectrometry method. The oxygen content is determined by using an inert gas fusion-IR absorption spectrometry method, while that of carbon is determined via a combustion-IR absorption spectrometry method or a combustion-conductometry method. The chlorine and fluorine contents are determined by using a pyrohydrolysation method followed by ion chromatography or spectrophotometry.

Fine ceramics (advanced ceramics, advanced technical ceramics) - Determination of densification properties of ceramic powders on natural sintering (ISO 21821:2019)
SIST EN ISO 21821:2023

This document specifies the test method to determine the extent to which ceramic powder compacts made of granulated or ungranulated ceramic powders are densified, when they are sintered at a high temperature without the application of any external pressure or external densification force. The test method is applicable to pure oxides, mixtures of oxides and solid solutions, and is also applicable to non-oxides (e.g. carbides, nitrides) that can be sintered under vacuum or constant gas pressure (1 bar or less) to prevent oxidation or decomposition. The test method is not applicable to ceramics that can only be sintered using pressure-assisted sintering techniques such as hot pressing (HP), hot isostatic pressing (HIP), gas pressure sintering (GPS) or spark plasma sintering (SPS). Inorganic sintering additives can be used where their presence is reported.
