SIST EN 13235:2007(Main)
Advanced technical ceramics - Mechanical properties of ceramic composites at high temperature under inert atmosphere - Determination of creep behaviour
EN 13235:2006

This European Standard specifies the conditions for the determination of the tensile creep deformation and failure behaviour of ceramic matrix composite materials with continuous fibre reinforcement for temperatures up to 2 000 °C under vacuum or in a gas atmosphere which is inert to the material under test. The purpose of these test conditions is to prevent changes to the material as a result of chemical reaction with the test environment.
This European Standard applies to all ceramic matrix composites with a continuous fibre reinforcement, unidirectional (1 D), bidirectional (2 D), and tridirectional (x D, where 2 ? x ? 3), loaded along one principal axis of reinforcement.

EN 623-1:2006

This part of EN 623 specifies qualitative methods for determination of the presence of defects in advanced technical ceramics by dye penetration tests. The results are reported as visual observations of dye penetration.
Three methods are described:
Method A:  A fuchsine dye test which is suitable for white or pale-coloured ceramic products, performed using an evacuation test.
Method B:  A fluorescent dye test which is suitable particularly for those products where the purple fuchsine has insufficient visual contrast with the ceramic material, performed using a proprietary test kit.
Method C:  A fuchsine dye test which is performed by simple immersion in or spraying with a dye solution, suitable for routine testing for major defects.

EN ISO 15732:2005

ISO 15732:2003 describes a test method for the determination of fracture toughness of monolithic ceramic materials at room temperature by the Single-Edge-Precracked-Beam (SEPB) method.
This International Standard is intended for use with monolithic ceramics and whisker- or particulate-reinforced ceramics which are regarded as macroscopically homogeneous. It does not include continuous-fiber-reinforced ceramic composites.
ISO 15732:2003 is for material development, material comparison, quality assurance, characterization, reliability and design data generation.
Fracture toughness values determined with other test methods cannot be interchanged with KIpb as defined in this International Standard, and may not be interchangeable with each other.

SIST EN 821-3:2005(Main)
Advanced technical ceramics - Monolithic ceramics. Thermo-physical properties - Part 3: Determination of specific heat capacity
EN 821-3:2005

This document specifies two methods for the determination of specific heat capacity of advanced monolithic technical ceramic materials based on drop calorimetry (Method A) and differential scanning calorimetry (DSC, Method B) over a temperature range from room temperature upwards, depending on the design of the equipment.
NOTE 1   The methods described apply in the case of test materials free from phase transformations, annealing effects or partial melting. If any such effect occurs in a material over the temperature range of the test, spurious results will be obtained unless the data are carefully analysed. In such cases it is usually necessary to conduct repeat tests at a number of temperatures close to the discontinuity, in order to estimate correctly its contribution to the apparent heat capacity.
NOTE 2   Care should be exercised in both methods over the selection of the cell or crucible material and in the selection of the test atmosphere, especially at high temperatures. Test pieces can react with the crucible or the atmosphere, leading to spurious results. In general, an awareness of such problems should be maintained at all times. Especially with regard to Method B, awareness should also be maintained of radiation effects at temperatures above 1000 °C, and of the reproducibility of the output signal.

Advanced technical ceramics - Monolithic ceramics - General and textural properties - Part 4: Determination of surface roughness
EN 623-4:2004

This part of EN 623 concerns the use of conventional stylus type instruments for the measurement of surface texture of advanced monolithic technical ceramics, sets the test machine measuring parameters, and recommends the adoption of certain precautions and conditions of measurement.
NOTE   Non-contact optical methods of surface texture measurement employ a different concept using a narrow laser beam. The interaction of the beam with the surface is influenced by the angle of the surface to the beam and the reflectivity/translucence of the surface. The reflected beam is detected in a number of ways based on spot focus or beam deflection and converted into a height profile. Results from such a test are not directly equivalent to those obtained by the stylus method.
