Telecommunications bonding networks for buildings and other structures
Käsitlusala: This document specifies requirements and provides recommendations for the design and installation of connections (bonds) between various electrically conductive elements in buildings and other structures, during their construction or refurbishment, in which information or telecommunications technology equipment is intended to be installed in order to:
a) minimise the d.c. and a.c. potential differences in order to reduce the risk of malfunction of that equipment and interconnecting cabling due to electromagnetic disturbance;
b) provide the telecommunications installation with a reliable signal reference – which may improve immunity from electromagnetic interference (EMI).
The requirements of this European Standard are applicable to the buildings and other structures within premises addressed by EN 50174 2 (e.g. residential, office, industrial and data centres) but information given in this European Standard may be of assistance for other types of buildings and structures.

Käsitlusala: This document describes the analytical procedures used to determine the content of tricalcium silicate (C3S), dicalcium silicate (C2S), tricalcium aluminate (C3A) and tetracalcium aluminoferrite (C4AF) of cement starting from a chemical analysis on cement. The method can be applied on all common cements as defined on EN 197-1.
This document also describes the calculation procedures for determining of tricalcium silicate (C3S), dicalcium silicate (C2S), aluminate (C3A) and tetracalcium aluminoferrite (C4AF) in the Portland cement clinker as defined in the EN 197-1.
In both cases, for cement and clinker, the calculation method is based on the Bogue method assuming each phase has a pure composition. This is a conventional method, whereby the actual mineralogical composition can differ from the results obtained using this method.
For the determination of the various chemical species of clinker, cement and basic-complexing residue (BCR) described in this document, the method is indicated in the relevant clause.

Method of testing cement - Part 17: Determination glass content of granulated blast furnace slag as constituent for common cement
Käsitlusala: This document describes two equivalent test methods for determining the glass content in Granulated blast furnace Slag (GBS) as constituent for common cement as defined on EN 197-1.
Method A - Method of determining the glass content of GBS by X-ray diffraction.
Method B - Method of determining the glass content of GBS by polarized optical microscopy.
The glass content (or glassy/amorphous phase) in GBS is the fraction of the material that lacks a crystalline structure, having solidified rapidly from the melt in the form of amorphous glass.
It is usually expressed as a percentage (wt%) of the total slag.
In the absence of a product standard or a specification in the product standard, the constituent is tested at the fineness of the intended use.
Furthermore, these test methods are used in manufacturing control of cement constituents for assessing their conformity to the limit indicated in EN 197-1.

Methods of testing cement - Part 15 - Sulfate resistance - Flat prism method
Käsitlusala: This document describes test methods (reference and alternative) applicable to cast test specimens for evaluating the Sulftate Resistance (SR characteristic) of cements. Sulfate resistance means that these binders can be used in concrete bodies submitted to sulfate attacks.

Käsitlusala: This document describes the method for determining the contribution of cement’s alkali to the alkali-silica reaction process that can occur in concrete or mortar containing aggregates potentially susceptible to alkali attack.
The principle is to consider the alkalis from the insoluble part of the cement (generally associated with fly ash, for example, or pozzolans) and the alkali from the diluted part of the cement (generally associated with clinker, gypsum, granulated blast furnace slag, or limestone) [1].
This test method can be used in the framework of preventing the risk of alkali silica reaction [2].
