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.

This document contains the general safety philosophy and a guideline on safety assessment that experts are recommended to use when drafting standards.
It also contains an Annex A with a collection of available anthropometric data and details of the abilities of children from birth to 48 months of age.
The general safety philosophy given in this part is based on the principle that child care articles should be designed to be safe.
Children with special needs have not been taken into account while drafting these guidelines. ISO/IEC Guide 71 can be consulted to ascertain any further requirements to address the hazards and risks associated with children with special needs.
These guidelines do not cover all types of hazards and risks, such as inappropriate use of products, inadequate supervision of children and products used in a non-domestic situation.
Attention is drawn to the importance of ensuring that all other potential hazards relevant to the product are fully addressed, e.g. hygiene, the effects of electrical power etc., where other safety standards can apply.

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 methods for:
—    determining the composition of a calibration gas mixture by comparison with appropriate reference gas mixtures;
—    calculating the uncertainty of the composition of a calibration gas mixture in relation to the known uncertainty of the composition of the reference gas mixtures with which it was compared;
—    checking the composition attributed to a calibration gas mixture by comparison with appropriate reference gas mixtures;
—    consistency testing and outlier search in suites of calibration gas mixtures of closely related composition.
NOTE 1    In principle, the method described in this document is also applicable to the analysis of (largely) unknown samples instead of prospective calibration gas mixtures (i.e. gas mixtures which are intended for use as calibration gas mixtures). Such applications, however, need appropriate care and consideration of additional uncertainty components, for example, concerning the effect of matrix differences between the reference gases used for calibration and the analysed sample.
NOTE 2    Comparison methods based on one- and two-point calibration are described in ISO 12963.

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.
