Earthing of power installations exceeding 1 kV a.c.
EN 50522:2022

This document is applicable to specify the requirements for the design and erection of earthing systems of
electrical installations, in systems with nominal voltage above 1 kV AC and nominal frequency up to and
including 60 Hz, so as to provide safety and proper functioning for the use intended.
NOTE 1 The technical and procedural principles of this document can be applied when third parties’ installations and

Oil-filled electrical equipment - Sampling of free gases and analysis of free and dissolved gases - Guidance
EN IEC 60567:2024

IEC 60567:2023 deals with the techniques for sampling free gases from gas-collecting relays from power transformers. Three methods of sampling free gases are described. The techniques for sampling oil from oil-filled equipment such as power and instrument transformers, reactors, bushings, oil-filled cables and oil-filled tank-type capacitors are no longer covered by this document, but are instead described in IEC 60475:2022, 4.2. Before analysing the gases dissolved in oil, they are first extracted from the oil. Three basic methods are described, one using extraction by vacuum (Toepler and partial degassing), another by displacement of the dissolved gases by bubbling the carrier gas through the oil sample (stripping) and the last one by partition of gases between the oil sample and a small volume of the carrier gas (headspace). The gases are analysed quantitatively after extraction by gas chromatography; a method of analysis is described. Free gases from gas-collecting relays are analysed without preliminary treatment.

Railway Applications - Requirements for software development
EN 50716:2023

1.1 This European Standard specifies the process and technical requirements for the development of software for programmable electronic systems for use in control, command for signaling applications and any on-board of rolling stock.
This European Standard is not intended to be applied in the area of electric traction power supply (fixed installation) or for power supply and control of conventional applications, e.g. station power supply for offices, shops etc. These applications are covered typically by standards for energy distribution and/or non-railway sectors and/or local legal frameworks.
For railway related fixed installations (electric traction power control and supply) the EN 50562 is applicable.
1.2 This European Standard is applicable exclusively to software and the interaction between software and the system of which it is part.
1.3 Intentionally left blank
1.4 This European Standard applies to all software used in railway systems, including
- application programming,
- operating systems,
- support tools,
- firmware.
Application programming comprises high level programming, low level programming and special purpose programming (for example: Programmable logic controller ladder logic).
1.5 This European Standard also addresses the use of pre-existing software and tools. Such software may be used, if the specific requirements in 7.3.4.7 and 6.5.4.16 on pre-existing software and for tools in 6.7 are fulfilled.
1.6 Software developed according to any version of EN 50128 or EN 50657 will be considered as compliant and not subject to the requirements on pre-existing software.
1.7 This European Standard considers that modern application design often makes use of software that is suitable as a basis for various applications. Such software is then configured by application data for producing the executable software for the application.
1.8 Entry intentionally left empty.
1.9 This European Standard is not intended to be retrospective. It therefore applies primarily to new developments and only applies in its entirety to existing systems if these are subjected to major modifications. For minor changes, only 9.2 applies.
The assessor has to analyse the evidences provided in the software documentation to confirm whether the determination of the nature and scope of software changes is adequate. However, application of this European Standard during upgrades and maintenance of existing software is highly recommended.
1.10 For the development of User Programmable Integrated Circuits (e.g. FPGA & CPLD) guidance is provided in EN 50129:2018 Annex F for safety related functions and in EN 50155:2017 for non-safety related functions. Software running on soft-cores of User Programmable Integrated Circuits is within the scope of this European Standard.

This document refers to manual blowpipes and stationary machine blowpipes with free burning flames for heat treatment of work pieces. These blowpipes are, due to their type of construction, designed for special applications and do not fall under the scope of EN ISO 5172:2006  and EN ISO 9012:2011.
This document does not apply to manual and machine cutting blowpipes according to EN ISO 5172:20061.
This document contains technical regulations, specifications and tests.
Blowpipes are intended for gaseous fuels in connection with oxygen, compressed air or aspirated air.
Flow rates are not expressly limited and depend on the thermal process to be performed.

Additive manufacturing for automotive - Qualification principles - Generic machine evaluation and specification of key performance indicators for PBF-LB/M processes (ISO/ASTM 52945:2023)
EN ISO/ASTM 52945:2024

This document defines the methodology for generic AM-machine evaluation in automotive
environment using objective test criteria and provides the framework for an objective AMmachine
evaluation and comparison. This document finds application in benchmarks,
preparation of purchase decisions, but also AM-machine evaluation within the machine
procurement, acceptance, and qualification process. The methodology and performance
characteristics are introduced to enable evaluation on an objective and quantitative basis. The
documentation resulting from the AM-machine evaluation is used to obtain a reliable orientation
selection and evaluation of PBF-LB/M AM-machines.
Furthermore, this document specifies machine KPIs in the context of machine procurement,
production planning and production of PBF-LB/M components. It aims to reach a detailed
understanding between machine supplier and machine customer with respect to the acceptance
criteria during the procurement process and evaluation of machine performance during running
production.
This document is applicable to the additive manufacturing technology LPBF-M defined in
ISO/ASTM 52900.
