This document specifies a method for the determination of nominal compressive strength of advanced monolithic technical ceramic materials at room temperature.

This document specifies methods for the chemical analysis of impurities present in aluminium oxide powders used as a raw material for fine ceramics. Aluminium oxide powders are decomposed by acid pressure decomposition, acid decomposition or alkali fusion. The calcium, chromium, copper, iron, magnesium, manganese, potassium, silicon, sodium, titanium, zinc and zirconium contents in the test solution are determined by an inductively coupled plasma-optical emission spectrometer (ICP-OES).

ISO 8894-2:2007 describes a hot-wire (parallel) method for the determination of the thermal conductivity of refractory products and materials.

This document specifies a method for determination of the cold compressive strength of dense shaped refractory products. Shaped refractories are those which have fixed geometry and dimensions when delivered to the user. This document is accordingly applicable to standard shape refractory bricks, but also special shapes refractory products and pre-cast products.

This document specifies a method for the determination of the modulus of rupture of dense and insulating shaped refractory products at ambient temperature, under conditions of a constant rate of increase of stress. Shaped refractories are those which have fixed geometry and dimensions when delivered to the user. This document is accordingly applicable to standard shape refractory bricks, but also special shapes refractory products and pre-cast products. This document is also applicable to unshaped refractories (see ISO 1927-6) after preparation of test specimens according to ISO 1927-5.

This International Standard describes a test method that covers the determination of fracture resistance of silicon nitride bearing balls at room temperature by the indentation fracture (IF) method, as specified in ISO 26602. This International Standard is intended for use with monolithic silicon nitride ceramics for bearing balls. It does not include other ceramic materials. This International Standard is for material comparison and quality assurance. Indentation fracture resistance, KI, IFR as defined in this International Standard is not to be equated to fracture toughness determined using other test methods such as KIsc and KIpb.

ISO 14705:2016 specifies a test method for determining the Vickers and Knoop hardness of monolithic fine ceramics at room temperature.
