This document describes methods for the determination of mineralogical phases often present as additives or reaction products in carbon containing or graphitic refractory products by X-ray Diffraction (XRD) using a Bragg-Brentano diffractometer. It includes details of sample preparation and general principles for qualitative and quantitative analysis of mineralogical phase composition. Quantitative determination of α-Si3N4, β-Si3N4, AlN, aluminium metal, Al4C3, silicon metal, boron carbide and BN are described. The problems encountered with some determinations are highlighted. Additional reduced species present in some refractories could include Al2O3⋅AlN solid solutions (so called Alons), Si3N4⋅SiO2 solid solutions and Si3N4⋅Al2O3 solid solutions (Sialons). The presence of some of these solid solution components will cause problems with both identification and quantification as they are not well-defined structures. NOTE     For rationalisation of nitrogen containing phases, the total nitrogen content, analysed in accordance with EN 12698-1 is used.

This document specifies a test method for determining the polytypes and their ratios in silicon carbide (SiC) wafers or bulk crystals using ultraviolet photoluminescence (UVPL) imaging. The range of SiC is limited to semiconductor SiC doped with nitrogen and boron to have a deep acceptor level and a shallow donor level, respectively. The SiC wafers or bulk crystals discussed in this document typically show electrical resistivities ranging from 10−3 ohm · cm to 10−2 ohm · cm, applicable to power electronic devices. This method is applicable to the SiC-crystal 4H, 6H and 15R polytypes that contain boron and nitrogen as acceptor and donor, respectively, at concentrations that produce donor-acceptor pairs (DAPs) to generate UVPL. In 4H-SiC the boron and nitrogen concentrations typically range from 1016 cm−3 to 1018 cm−3. Semi-insulating SiC is not of concern because it usually contains minimal boron and nitrogen; therefore deep level cannot be achieved.

This European Standard gives a method of determining the design value of the bending strength of glass. It gives:
- the general method of calculation, and
- guidance for lateral load resistance of linearly supported glazed elements used as infill panels;
NOTE   Examples of lateral loads are wind loads and snow loads and self weight of sloping glass and climatic loads on insulating glass units.
This standard gives recommended values for the following factors for glass as a material:
-  material partial factors, γM;A and γM;v ;
-  factors for the load duration, kmod ;
- partial factor for actions, γG , γQ , and ψ ;
- factor for stressed edges, ke.
Most glass in buildings is used as infill panels.  Infill panels are in a class of consequence lower than those covered in EN 1990, so proposed values for the partial load factors, γQ and γG, are given for infill panels.
The action of climatic loads on insulating glass units is not covered by Eurocodes, so this document also gives proposed values of partial factors, ψ0, ψ1 and ψ2, for this action.
This European Standard does not determine suitability for purpose. Resistance to lateral loads is only one part of the design process, which may also need to take into account, for example:
- in-plane loading, buckling, lateral torsional buckling, and shear forces
- environmental factors (e.g. sound insulation, thermal properties),
- safety characteristics which cannot be calculated (e.g. fire performance, breakage characteristics in relation to human safety, security, containment).
This European Standard does not apply to channel shaped glass.

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.

This document gives a method of determining the design value of the bending strength of glass. It gives:the general method of calculation, and guidance for lateral load resistance of linearly supported glazed elements used as infill panels
NOTE   Examples of lateral loads are wind loads, snow loads, self weight of sloping glass, and cavity pressure variations on insulating glass units.
This document gives recommended values for the following factors for glass as a material:
- material partial factors, M;A and M;v ;
- factors for the load duration, kmod ;
- factor for stressed edges, ke.
Most glass in buildings is used as infill panels.  This document covers those infill panels that are in a class of consequence lower than those covered in EN 1990, so proposed values for the partial load factors, yQ and yG, are given for these infill panels.
The action of cavity pressure variations on insulating glass units is not covered by Eurocodes, so this document also gives proposed values of partial factors, 0, 1 and 2, for this action.
This document does not determine suitability for purpose. Resistance to lateral loads is only one part of the design process, which could also need to take into account:
-   in-plane loading, buckling, lateral torsional buckling, and shear forces,
-   environmental factors (e.g. sound insulation, thermal properties),
-   safety characteristics (e.g. fire performance, mode of breakage in relation to human safety, security).
This document does not apply to channel shaped glass, glass blocks and pavers, or vacuum insulated glass units.

This document specifies a test method for determining the mechanical viscoelastic properties of interlayer materials. The interlayers under examination are those used in the production of laminated glass and/or laminated safety glass. The interlayer viscoelastic properties are needed in order to determine the load resistance of laminated glass.
From the tensile modulus in particular conditions of temperature and load duration, an interlayer can be placed into a family that relates to a specific interlayer shear transfer coefficient.  This value can be used in the simplified calculation method described in EN 16612.
Informative Annex D explains the background to the determination of families relating to a specific interlayer shear transfer coefficient.

This document specifies a test method for the determination of the air-purification performance of materials that contain a photocatalyst or have photocatalytic films on the surface, usually made from semiconducting metal oxides, such as titanium dioxide or other ceramic materials, by continuous exposure of a test piece to the model air pollutant under irradiation with ultraviolet light (UV-A). This document is intended for use with different kinds of materials, such as construction materials in flat sheet, board or plate shape, that are the basic forms of materials for various applications. This document also applies to structured filter materials including honeycomb-form, woven and non-woven fabrics, and to plastic or paper materials if they contain ceramic microcrystals and composites. This document does not apply to powder or granular photocatalytic materials. This test method is usually applicable to photocatalytic materials produced for air purification. This method is not suitable for the determination of other performance attributes of photocatalytic materials, i.e. decomposition of water contaminants, self-cleaning, antifogging and antibacterial actions. It concerns the removal of toluene.

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), bidirectional (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.

This European Standard specifies tolerances, flatness, edgework, fragmentation and physical and mechanical characteristics of monolithic flat thermally toughened soda lime silicate safety glass for use in buildings.
Information on curved thermally toughened soda lime silicate safety glass is given in Annex A, but this product does not form part of this European Standard.
Other requirements, not specified in this European Standard, can apply to thermally toughened soda lime silicate safety glass which is incorporated into assemblies, e.g. laminated glass or insulating glass units, or undergo an additional treatment, e.g. coating. The additional requirements are specified in the appropriate glass product standard. Thermally toughened soda lime silicate safety glass, in this case, does not lose its bending strength characteristics and its resistance to temperature differentials.
Surface finished glasses (e.g. sandblasted, acid etched) after toughening are not covered by this European Standard.

This European Standard assigns sound insulation values to all transparent, translucent and opaque glass products, described in the European Standards for basic, special basic or processed glass products, when intended to be used in glazed assemblies in buildings, and which exhibit properties of acoustic protection, either as a prime intention or as a supplementary characteristic.
This document outlines the procedure, by which glass products may be rated, according to their acoustic performance which enables assessment of compliance with the acoustic requirements of buildings.
Rigorous technical analysis of measurement data remains an option, but this standard is intended to enable the derivation of simpler indices of performance, which can be adopted with confidence by non-specialists.
By adopting the principles of this standard the formulation of acoustic requirements in Building Codes and for product specification to satisfy particular needs for glazing is simplified.
It is recognised that the acoustic test procedures contained within EN ISO 140-1 and EN ISO 140-3 relate only to glass panes and their combinations. Although the same principles should be followed as closely as possible, it is inevitable that some compromises are necessary, because of the bulkier construction of other glazing types, e.g. glass blocks, paver units, channel-shaped glass, structural glazing and structural sealant glazing. Guidelines on how to adapt the test procedures for these glazing types are offered in Clause 4.
All the considerations of this standard relate to panes of glass/glazing alone. Incorporation of them into windows may cause changes in acoustic performance as a result of other influences, e.g. frame design, frame material, glazing material/method, mounting method, air tightness, etc. Measurements of the sound insulation of complete windows (glass and frame) may be undertaken to resolve such issues.
