Building valves - Pressure safety valves - Tests and requirements

This document specifies dimensions, materials and performance requirements, including methods of test, for pressure safety valves, of nominal sizes from DN 15 to DN 40, having working pressures from 0,1 MPa (1 bar) to 1,0 MPa (10 bar). Pressure safety valves are intended for fitting to the potable water supply of storage water heaters, having a maximum storage temperature of 95 °C. Pressure safety valves limit the pressure in hot water heaters. Pressure safety valves do not control the temperature and alone do not constitute the protection required for storage water heaters. They are not intended to act as expansion valves under normal conditions. NOTE The use of the device specified in this document does not override the need to use controls (e.g. thermostats and cut-outs) which act directly on the power sources of water heaters (for more information see Annex A).

Plastics - Determination of tensile properties - Part 6: Measurement of strain distribution for randomly oriented chopped strand- or fibre- reinforced plastic composites (ISO/DIS 527-6:2026)

This document outlines methods for measuring the strain distribution for randomly oriented chopped strand- or fibre-reinforced plastic composites, based upon the general principles given in ISO 527-4. The methods are used to statistically evaluate the inherent variation of strain-based properties. The main purpose of this document compared to existing standards is to evaluate the strain distribution due to the random orientation of chopped fibres, while ISO 527-4 is sufficient for evaluating only the bulk elastic modulus. This standard provides two methods for evaluating an inherent strain distribution of the material, Method A as using DIC analysis system and Method B as using several strain gauges with a short gauge length. The methods are suitable for use with fibre-reinforced thermosetting and thermoplastic composites incorporating discontinuous or chopped reinforcements such as mats, chopped strands or tapes, long-fibre injection or combination of such reinforcements. The methods are not normally suitable for continuous fibre-reinforced materials which generate homogeneous strain distribution on the surface of the test specimen.

Portable equipment for projecting extinguishing agents and firefighting support operations — Hand-held branchpipes for fire service use — Part 3: Smooth bore and/or one fixed spray jet angle branchpipes PN 16

In addition to the common requirements given in EN 15182-1, this document specifies the specific safety and performance requirements and the corresponding test methods, applicale to hand-held branchpipes with smooth bore and/or one fixed spray jet angle with a nominal pressure of 16 bar (1,6 MPa) PN 16, with a maximum flow rate up to 1 000 l/min at a reference pressure of 6 bar (0,6 MPa). NOTE 1 These branchpipes offer no or inadequate protection for firefighters when the spray jet angle is less than 30 ° and therefore are not adapted in high risk firefighting situations such as internal attack. NOTE 2 These branchpipes are not adapted when fighting fires in or near electrical installations when the spray jet angle is less than 30° without written authorization in the manual (safety distances included).

Fire resistance tests for service installations - Part 1: Ventilation ducts

This document specifies a method for determining the fire resistance of vertical and horizontal ventilation ducts including ancillary items such as access panels, attenuators, compensators and control dampers, which are integral part of the tested ducts. The test examines the behaviour of ducts exposed to fire from the outside (duct A) and fire inside the duct (duct B). This document is used in conjunction with EN 1363-1. Annex A provides general guidance and gives background information. This document is not applicable to: a) ducts whose fire resistance depends on the fire resistance performance of a ceiling or wall (where ducts are located in cavities enclosed by fire-resistant shafts or ceilings); b) ducts containing fire dampers at points where they pass through fire separations; c) one, two or three sided ducts; d) fixing of suspension devices (e.g. anchors) to floors or walls.

Health informatics - Electronic health record communication - Part 5: Interface specification (ISO/DIS 13606-5:2026)

This document specifies the information architecture required for interoperable communications between systems and services that need or provide EHR data. This document is not intended to specify the internal architecture or database design of such systems. The subject of the record or record extract to be communicated is an individual person, and the scope of the communication is predominantly with respect to that person's care. Uses of healthcare records for other purposes such as administration, management, research and epidemiology, which require aggregations of individual people's records, are not the focus of this document but such secondary uses could also find the document useful. This document defines a set of interfaces to request and provide: — an EHR_EXTRACT for a given subject of care as defined in ISO 13606-1; — one or more ARCHETYPE(s) as defined in ISO 13606-2; — an EHR_AUDIT_LOG_EXTRACT for a given subject of care as defined in ISO 13606-4. This document defines the set of interactions to request each of these artefacts, and to provide the data to the requesting party or to decline the request. An interface to query an EHR or populations of EHRs, for example for clinical audit or research, are beyond its scope, although provision is made for certain selection criteria to be specified when requesting an EHR_EXTRACT which might also serve for population queries. This document defines the Computational Viewpoint for each interface, without specifying or restricting particular engineering approaches to implementing these as messages or as service interfaces. This document effectively defines the payload to be communicated at each interface. It does not specify the particular information that different transport protocols will additionally require, nor the security or authentication procedures that might be agreed between the communicating parties or required by different jurisdictions.
