This document describes how product catalogue data for building services products is exchanged by means of ISO 16739-1 (Industry Foundation Classes, IFC) and EN 17549-2 from manufacturers to designers of building services systems.
This document specifies how the product catalogue structures and content are set up using the definitions stored in a data dictionary.
In scope of this document are:
— processes for the provision and exchange of product catalogues;
— rules for the geometrical representation of products;
— representation of products, product classes, ports, in/outlets, components and accessories by using IFC;
— representation of properties in IFC and the use of IFC constraints for the representation of product variants;
— representation of parametric geometry and the generation of IFC geometries for selected variants;
— calculation of article number.
The resulting product catalogue can be used by designers to select the desired products and integrate them into their model of the building services system.
The expected audience of this document are software providers for the built environment sector and professionals working in the sector who create product catalogues or use product catalogues by means of software tools.
Not in scope of this document is the representation of properties in data dictionaries. The use of data dictionaries is described in ISO 16757-4.

This document specifies requirements for data dictionaries that are used by product catalogues for building services to provide the semantics of their definitions and data modelling. For this purpose, it defines an overall model that contains:
— subject kinds that allow to distinguish:
— product subjects representing products in product catalogues;
— catalogue subjects comprising meta data of product catalogues;
— various kinds of blocks that collect properties of complex product features, including ports and in/outlets;
— relationship types that allow to distinguish between different kinds of relationships like isSubtypeOf, hasPart, or hasBlock;
— property kinds to distinguish between:
— static properties describing products by providing property values in product catalogues;
— dynamic properties that describe the behaviour of products;
— external properties that represent external conditions that influence the behaviour of the product by influencing the values of dynamic properties.
This document also describes a mapping of the overall model to the data dictionary model of ISO 12006-3 by introducing a dictionary meta level.
Finally, to overcome deficiencies of the standards underlying ISO 16757-5 in capturing all aspects of product catalogues, this document provides some rules and recommendations for required data dictionary elements.
This document does not describe how product catalogues have to be organized, and it does not describe any formats for the exchange of product catalogues. Product catalogues are described in ISO 16757-5.

This document specifies the methods for the chemical analysis of cement.
This document describes the reference methods and, in certain cases, an alternative method which can be considered to be equivalent. In the case of a dispute, only the reference methods are used.
An alternative performance-based method using X-ray fluorescence (XRF) is described for SiO2, Al2O3, Fe2O3, CaO, MgO, SO3, K2O, Na2O, TiO2, P2O5, Mn2O3, SrO, Cl and Br. This method is based on beads of fused sample and analytical validation using certified reference materials, together with performance criteria. A method based on pressed pellets of un-fused sample can be considered as equivalent, providing that the analytical performance satisfies the same criteria.
An alternative performance-based method using inductively coupled plasma optical emission spectroscopy (ICP-OES) is described for SO3.
When correctly calibrated according to the specified procedures and reference materials, XRF and ICP-OES provides methods equivalent to the reference methods but has not been validated for use yet as a reference procedure for conformity and dispute purposes. They can be applied to other relevant elements when adequate calibrations have been established.
Any other methods can be used provided they are calibrated, either against the reference methods or against internationally accepted reference materials, in order to demonstrate their equivalence.
This document describes methods which apply principally to cements, but which can also be applied to their constituent materials. They can also be applied to other materials, the standards for which call up these methods. Standard specifications state which methods are to be used.

When correctly calibrated according to the specified procedures and reference materials, XRF and ICP-OES provides methods equivalent to the reference methods but has not been validated for use yet as a reference procedure for conformity and dispute purposes. They can be applied to other relevant elements when adequate calibrations have been established.
Any other methods can be used provided they are calibrated, either against the reference methods or against internationally accepted reference materials, in order to demonstrate their equivalence.
This document describes methods which apply principally to cements, but which can also be applied to their constituent materials. They can also be applied to other materials, the standards for which call up these methods. Standard specifications state which methods are to be used.

This document deals with special requirements and performance criteria for the design of lining systems made of steel for free standing chimneys. It specifies the requirements for cylindrical steel liners as stated in EN 13084-1.
This document covers the design of the following three basic types of liners located in a load bearing structure:
a) base supported liner;
b) sectional liner;
c) top hung liner.
Additionally, this document applies to single wall chimneys regarding their contact with flue gases.
For simplicity, these various designs will generally be referred to herein as "liners".
The mechanical requirement is not part of this document; for information, see EN 1993-3.
NOTE Liners built from prefabricated metal chimneys in accordance with EN 1856-1:2009 and EN 1856-2:2009 are installed as base supported liners with additional supports and guides as defined in this document.
