kSIST FprEN 17015-1:2024

The purpose of this deliverable is to specify and describe choreographies for exchanging an electronic product catalogue (“catalogues”) as part of the business processes in the pre-award and post-award area, so that catalogues can serve as a basis for placing orders as well as evaluating tenders. The key aspects covered by this choreography specification are:
-   processes for submitting catalogues from the selling to the buying side;
-   processes for submitting catalogue-related data as part of a tendering process;
-   processes integrating sell-side procurement systems.
This document does not apply to the transactions used in the specified choreographies. These transactions are specified in EN 17015 2. The relationship between the choreographies and the transaction is described in Clause 8.
The identifier of this choreographies document is EN 17015 1:2024.
How to claim compliance to this choreography is specified in 6.2.3.

This edition of the document added coverage of information required for infrastructure facilities including bridges, roads, railways, waterways and port facilities.
This document comprises the publication of a data schema, its documentation, the property and quantity set definitions and the mechanism of an exchange file format structure.
Definitions from this document are used to support different recognized work flows in the construction and facility management industry sector, representing information deliveries. Such information deliveries can be described according to ISO 29481.
Different implementation levels of this document can be defined to better support multiple information deliveries, they are referred to as a Model View Definition (MVD). Each MVD identifies which subset of the definitions of this document imposes requirements for implementation in software applications. Conforming software applications need to identify the model view definition they conform to when applying for software certification.

Water quality - Application of inductively coupled plasma mass spectrometry (ICP-MS) - Part 1: General requirements (ISO 17294-1:2024)
kSIST FprEN ISO 17294-1:2023

This document specifies the principles of inductively coupled plasma mass spectrometry (ICP-MS) and provides general requirements for the use of this technique to determine elements in water, digests of sludges and sediments (e.g. digests of water as described in ISO 15587-1 or ISO 15587-2). Generally, the measurement is carried out in water, but gases, vapours or fine particulate matter can be introduced too. This document applies to the use of ICP-MS for aqueous solution analysis.
The ultimate determination of the elements is described in a separate International Standard for each series of elements and matrix. The individual clauses of this document refer the user to these guidelines for the basic principles of the method and the configuration of the instrument.
