Gas cylinders - Cylinder valves with integrated pressure regulators - Specification and type testing (ISO 22435:2024)
kSIST FprEN ISO 22435:2024

This document specifies design, type test methods, marking and instruction requirements for cylinder valves with integrated pressure regulators (VIPRs) intended to be fitted to gas cylinders, pressure drums or tubes or used as a main valve for bundles of cylinders that convey compressed, liquefied or dissolved gases.
These are requirements for VIPRs that are in addition to those given in the relevant closure standard, for example, in ISO 10297 for cylinder valves, in ISO 17871 for quick-release cylinder valves, in ISO 17879 for self-closing cylinder valves or in ISO 23826 for ball valves. For ISO 17871, these requirements are only applicable to quick-release cylinder valves types B, C, D and E.
NOTE 1        If the pressure regulating system of a VIPR is acting as the primary valve operating mechanism, it is covered by the relevant closure standard, e.g. ISO 10297, ISO 17871, ISO 17879 and ISO 23826. This also includes designs where closure of the primary valve operating mechanism of a VIPR is obtained by closing the seat of the pressure regulating system.
NOTE 2        If the primary valve operating mechanism of a VIPR is located at the low-pressure side of the pressure regulating system, it is covered by the relevant closure standard, e.g. ISO 10297, ISO 17871, ISO 17879 and ISO 23826.
NOTE 3        The term “pressure receptacle” is used within this document to cover instances where no differentiation is necessary between gas cylinders, bundles of cylinders, pressure drums and tubes.
This document does not apply to VIPRs for
a)       medical applications (see ISO 10524-3);
b)       liquefied petroleum gas (LPG);
c)        cryogenic applications.
NOTE 4        Additional requirements for a VIPR with a residual pressure device (RPD) are specified in ISO 15996.
NOTE 5        Additional requirements for pressure relief valves can exist in international/regional regulations/ standards.

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 document represents an open international standard for information used in Building Information Modeling (BIM) that is exchanged and shared among software applications used by the various participants in the construction or facility management industry sector. This document includes definitions that cover information required for buildings and infrastructure works over their life cycle. 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.
The following are within the scope of this edition of this document:
BIM exchange format definitions that are required during the life cycle phases of buildings and infrastructure:
demonstrating the need;
conception of need;
outline feasibility;
substantive feasibility study and outline financial authority;
outline conceptual design;
full conceptual design;
coordinated design;
procurement and full financial authority;
production information;
construction;
operation and maintenance.
BIM exchange format definitions that are required by the various disciplines involved within the life cycle phases:
architecture and civil engineering design;
service and utilities engineering;
structural engineering;
procurement;
construction planning;
facility and utility management;
project management;
client requirement management;
industry authorities for permits and approval.

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.
