IEC 60079-28:2025 specifies additional requirements for Ex Equipment, Ex associated equipment or Ex Components containing optical systems emitting optical radiation, which is exposed to explosive atmospheres. These additional requirements are applicable for all equipment groups and all Equipment Protection Levels (EPL).
This document contains requirements for optical radiation in the wavelength range from 380 nm to 10 µm. It covers the following ignition mechanisms:
• Optical radiation is absorbed by surfaces or particles, causing them to heat up, and under certain circumstances this might allow them to attain a temperature which will ignite a surrounding explosive atmosphere.
• In rare special cases, direct laser induced breakdown of the gas at the focus of a strong beam, producing plasma and a shock wave both eventually acting as ignition source. These processes can be supported by a solid material close to the breakdown point.
• Annex A provides guidance when considering ignition mechanisms that influence the hazard of optics in explosive atmospheres.
This document applies to
a) laser equipment; and
b) optical fibre equipment; and
c) any optical system that converts light into convergent beams with focal points within the hazardous area only.
This document does not apply to:
d) laser equipment for EPL Mb, Gb, Gc, Db or Dc applications which complies with Class 1 limits in accordance with IEC 60825-1; or
e) Single or multiple optical fibre cables not part of optical fibre equipment if the cables:
1) comply with the relevant industrial standards for optical fibre cables, along with additional protective means, for example robust cabling, conduit or raceway (for EPL Gb, Db, Mb, Gc or Dc); or
2) comply with the relevant industrial standards for optical fibre cables (for EPL Gc or Dc); or
f) Optical radiation sources as defined in i) to iii) above where the optical radiation is fully contained in an enclosure complying with one of the following Types of Protection suitable for the EPL, or the minimum ingress protection rating specified:
1) flameproof "d" enclosures (IEC 60079-1); or
2) pressurized "p" enclosures (IEC 60079-2); or
3) restricted breathing "nR" enclosure (IEC 60079-15); or
4) dust protection "t" enclosures" (IEC 60079-31); or
5) an enclosure that provides a minimum ingress protection of IP 6X and where no internal absorbers are to be expected and complying with "Tests of enclosures" in IEC 60079-0.
This document does not cover ignition by ultraviolet radiation and by absorption of the radiation in the explosive mixture itself. Explosive absorbers or absorbers that contain their own oxidizer as well as catalytic absorbers are also outside the scope of this document.
This document supplements and modifies the general requirements of IEC 60079-0. Where a requirement of this document conflicts with a requirement of IEC 60079-0, the requirement of this document takes precedence.

IEC TS 63529:2026, which is a Technical Specification, is intended to inform and guide the harmonic design of the DC side of HVDC projects. It considers all aspects of AC current and voltage occurring on the DC circuit and also the interaction with adjacent systems.
The switching action in HVDC converters results in a wide spectrum of harmonics. These range from the fundamental frequency to the radio frequency range. Traditionally the specification of DC side harmonic performance has been limited to the frequency range of interest for induced audible noise on nearby telephone systems. Often a limit of 50th harmonic has been applied, corresponding to 2 500 Hz or 3 000 Hz on 50 Hz and 60 Hz systems respectively. Occasionally the range has been extended to 5 000 Hz. This frequency range has corresponded to the spectrum of characteristic harmonic generation from thyristor line commutated converters (LCC).
The introduction of HVDC voltage sourced converters (VSC) has meant that although the magnitude of DC side harmonic generation from these converters is generally lower, the generated spectrum of interest extends to higher frequencies.
The scope of this document therefore covers the frequency range up to approximately 5 000 Hz. Higher frequencies are mentioned only when relevant. The scope excludes the much higher frequency ranges appropriate to PLC communication and the radio interference spectra.

This document specifies the functional requirements relevant for design, materials, construction, testing, operation and maintenance of gas pressure control stations to ensure their reliability in terms of safety of the station itself and the downstream system and continuity of service.
This document is applicable for gas pressure control stations which are part of gas transmission or distribution systems for hydrogen, and hydrogen rich, and methane rich gases. Additional requirements in the case of gases heavier than air and/or toxic or corrosive gases are not covered by this document.
This document does not apply to gas pressure control stations in operation prior to the publication of this document. However, Annex D of this document can be used as guidance for the evaluation of stations in operation prior to the publication of this document, regarding the change of the type of gas, e.g. repurposing for the use with hydrogen.
The stations covered by this document have a maximum upstream operating pressure, which does not exceed 100 bar. For higher maximum upstream operating pressures, this document can be used as a guideline.
If the inlet pipework of the station is a service line and the maximum upstream operating pressure does not exceed 16 bar and the design flow rate is equal to 2000 kW based on the gross calorific value or less, EN 12279 applies.
This document contains the basic system requirements for gas pressure control stations. Requirements for individual components (valves, regulators, safety devices, pipes, etc.) or installation of the components are contained in the appropriate European Standards.
NOTE For combined control and measuring stations, the additional requirements of EN 1776 can apply.
The requirements in this document do not apply to the design and construction of auxiliary facilities such as sampling, calorimetering, odorization systems and density measuring. These facilities are covered by the appropriate European Standards, where existing, or applicable national standards.
The requirements of this document are based on good gas engineering practice under conditions normally encountered in the gas industry. Requirements for unusual conditions cannot be specifically provided for, nor are all engineering and construction details prescribed.
The objective of this document is to ensure the safe operation of such stations. This does not, however, relieve all concerned of the responsibility for taking the necessary care and applying effective quality and safety management during the design, construction, operation and maintenance.

The motors within this document:
- have a rated power PN from 0,12 kW to 1 000 kW;
- have a rated voltage UN from 50 V up to and including 1 000 V;
- have 2, 4, 6 or 8 poles;
- are capable of continuous operation at their rated power with a temperature rise within the specified insulation temperature class;
NOTE 1 Most motors covered by this document are rated for duty type S1 (continuous duty). However, some motors that are rated for other duty cycles are still capable of continuous operation at their rated power, and these motors are also covered by this document.
- are marked with any ambient temperature within the range of –30 °C to +60 °C;
NOTE 2 The rated efficiency and efficiency classes are based on 25 °C ambient temperature in accordance with IEC 60034‑2‑1.
NOTE 3 Motors exclusively rated for temperatures outside the range – 30 °C and +60 °C are considered to be of special construction and are consequently excluded from this document.
NOTE 4 Smoke extraction motors with a temperature class of up to and including 400 °C are covered by this document.
- are marked with an altitude up to 4 000 m above sea level.
NOTE 5 The rated efficiency and efficiency class are based on a rating for altitudes up to 1 000 m above sea level.
This document establishes a set of nominal efficiency values based on supply frequency, number of poles and motor output power. No distinction is made between motor technologies, supply voltage or motors with increased insulation designed specifically for converter operation even though not all motor technologies are capable of reaching the higher efficiency classes (see Table 1). This makes different motor technologies fully comparable with respect to their energy efficiency potential.
The efficiency of power-drive systems is not covered by this document. Motor losses due to harmonic content of the supply voltage, losses in cables, filters and frequency-converters, are not covered.
Motors with flanges, feet or shafts with mechanical dimensions different from IEC 60072‑1 are covered by this document.
Geared motors are covered by this document including those incorporating non-standard shafts and flanges.
This document does not apply to the following:
- Single-speed motors with 10 or more poles or multi-speed motors.
- Motors with mechanical commutators (such as DC motors).
- Motors completely integrated into a machine (for example pump, fan and compressor) that cannot be practically tested separately from the machine even with provision of a temporary end-shield and drive-end bearing. This means the motor: a) shares common components (apart from connectors such as bolts) with the driven unit (for example, a shaft or housing) and b) is not designed in such a way as to enable the motor to be separated from the driven unit as an entire motor that can operate independently of the driven unit. That is, for a motor to be excluded from this document, the process of separation shall render the motor inoperative.

16614 (NeTEx) is composed of a series of standards:
- Part 1: Description of the public transport network topology exchange format.
- Part 2: Description of the scheduled timetables exchange format.
- Part 3: Description of the fare information exchange format.
- Part 4: Description of the passenger information European profile (EPIP).
- Part 5: Description of the alternative modes exchange format.
- Part 6: Description of the accessibility European profile (EPIAP).
The present update concerns Part 3.
All the parts will be updated together, except Part 6 currently under formal vote (a NWI is produced for each Part). This update is done in a similar timeframe as the Transmodel (EN12896) revision, to achieve the best possible consistency.
The updated version of TS 16614 is going to be published as NeTEx v2.
The global updates consist in the following main extensions/enhancements:
- Deck plan allowing for a digitalised representation of spaces and equipment on board vehicles (with considerations of accessibility features),
- Physical layout of compound vehicles (e.g. train composition),
- Multiple minor enhancements, adjustments, and fixes to consider all the feedback from the previous versions of NeTEx, especially in the context of the European Delegated Regulation EU 2017/1926
Consistency and coherences with Transmodel and SIRI and OJP have also been challenged and minor updates are to be integrated in this revision.

This part of IEC 62541 defines the OPC Unified Architecture (OPC UA) Services. The Services defined are the collection of abstract Remote Procedure Calls (RPC) that are implemented by OPC UA Servers and called by OPC UA Clients. All interactions between OPC UA Clients and Servers occur via these Services. The defined Services are considered abstract because no particular RPC mechanism for implementation is defined in this document. IEC 62541-6 specifies one or more concrete mappings supported for implementation. For example, one mapping in IEC 62541-6 is to UA-TCP UA-SC UA-Binary. In that case the Services described in this document appear as OPC UA Binary encoded payload, secured with OPC UA Secure Conversation and transported via OPC UA TCP.
Not all OPC UA Servers implement all of the defined Services. IEC 62541-7 defines the Profiles that dictate which Services must be implemented in order to be compliant with a particular Profile.
A BNF (Backus-Naur form) for browse path names is described in Annex A.
