IEC 62541-100:2025 defines the information model associated with Devices. This document describes three models which build upon each other as follows:
• The (base) Device Model is intended to provide a unified view of devices and their hardware and software parts irrespective of the underlying device protocols.
• The Device Communication Model adds Network and Connection information elements so that communication topologies can be created.
• The Device Integration Host Model finally adds additional elements and rules required for host systems to manage integration for a complete system. It enables reflecting the topology of the automation system with the devices as well as the connecting communication networks.
This document also defines AddIns that can be used for the models in this document but also for models in other information models. They are:
• Locking model – a generic AddIn to control concurrent access,
• Software update model – an AddIn to manage software in a Device.

IEC 62541-4:2025 is available as IEC 62541-4:2025 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 62541-4:2025 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. This fourth edition cancels and replaces the third edition published in 2020. This edition constitutes a technical revision.

IEC 62541-17:2025 provides a definition of AliasNames functionality. AliasNames provide a manner of configuring and exposing an alternate well-defined name for any Node in the system. This is analogous to the way domain names are used as an alias to IP addresses in IP networks. Like a DNS Server, an OPC UA Server that supports AliasNames provides a lookup Method that will translate an AliasName to a NodeId of the related Node on a Server. An aggregating Server can collect these AliasNames from multiple Servers and provide a lookup Method to allow Client applications to discover NodeIds on a system wide basis. An aggregating Server could also define AliasNames for Nodes in other Servers that do not support AliasNames. A GDS can be constructed that would automatically aggregate all AliasNames that are defined on any Server that has registered with the GDS. In this case, the GDS also provides the lookup mechanism for Clients at a well-known endpoint and address.

This document describes a shared conceptual framework for the nuclear digital ecosystem (NDE). In addition, this framework also serves as a systematic basis for a series of additional standards for management methods and technical guidelines for information integration and exchange, specifically in the nuclear industry. The framework focuses on the nuclear industry-specifics with management requirements as well as information specifications to facilitate practical benefits from implementing ISO standards. It is viable because the industry scope is narrowed down to the nuclear sector, while the management concerns are expanded to cover the various disciplines throughout the entire life cycle. The following are within the scope of this document: — definition of the conceptual structure of the nuclear ecosystem with components and relationships in terms of facility type, life cycle (lifetime), and technical management methodology; the scope of this document exclusively addresses ‘all reactor-related facilities’; — definition of the industry sectors involved within NDE, encompassing civil, architectural, mechanical, electrical, I&C, process engineering and ICT; — list of high-level constituents for each component; — instructions to guide the collective use of this document and existing standards to specify information requirements within the NDE for different functional purposes. The following are outside the scope of this document: — definition of detailed management methodologies or processes related to the standard data exchange; — list of detailed properties and structures of the required information exchange (IE).

IEC TR 61508-3-3:2025 makes a proposal as to which topics to consider and which methods and techniques to use when designing object-oriented software to ensure suitable quality for use in functional safety applications.
Object-oriented languages are perceived as "state-of-the-art" nowadays. Such languages seem to be excluded from use by several statements in IEC 61508-3. However there are additions in some tables such as in IEC 61508-3:2010, Table B.1, where notes are added under which their use might be justified. Such exceptions that would allow, for example, dynamic objects, name the main concerns such as memory allocation and predictable timing issues and guide the user to safe use of object-oriented languages. These considerations are taken up in this document to specify methods and techniques that allow the reduction of systematic faults to the levels required by the respective systematic capabilities.
This document is not intended to replace any part of IEC 61508-3. Rules that exist in IEC 61508‑3 are valid here as well and are not repeated, including rules that concern:
• the software life cycle,
• involvement of the assessor,
• modularization,
• principle of information hiding,
• proving and conventional testing,
• basic aspects of documentation,
• low coupling and high cohesion,
• responsibilities and training of people,
• operational experience as described in IEC 61508-4 and IEC 61508-7
This TR is a supplement to the IEC 61508 standard series. It has to be read in conjunction with IEC 61508-3 and proposes a way how the use of object-oriented software in safety relevant applications can be justified.

The ISO 10303 series are the ISO standards adopted for the engineering data exchange, sharing and long-term archiving of product definition information throughout the product lifecycle. In this document 3D visualization is defined as the visual presentation on a screen or another media of graphical and textual 3 dimensional representations of a set of data representing an object, information or results of a computational process in order to enable decision process by a human looking at the data visualized in a medium. The file format supports the following information: — facet information (triangles), stored with geometry compression techniques; — visual attributes such as lights, textures and materials; — product manufacturing information, such as dimensions, tolerances and other attributes; — boundary representation (b-rep) solid model shape representations. Several alternatives are available, including a representation based on the geometry standard defined in ISO 10303; — configuration representations; — delivery methods such as asynchronous streaming of content. The document does not specify the implementation of, or definition of a run-time architecture for viewing or processing of the file format.

IEC 61967-7:2025 defines SystemC® with Transaction Level Modeling (TLM) as an ISO standard C++ class library for system and hardware design. SystemC®1 as an ANSI standard C++ class library for system and hardware design.
The general purpose of this standard is to provide a C++-based standard for designers and architects who need to address complex systems that are a hybrid between hardware and software. The specific purpose of this standard is to provide a precise and complete definition of the SystemC class library including a TLM library so that a SystemC implementation can be developed with reference to this standard alone. This standard is not intended to serve as a user’s guide or to provide an introduction to SystemC, but it does contain useful information for end users.
The changes with respect to the previous edition are provided in Annex D.
This standard is published as a double logo IEC-IEEE standard.

IEC 62014-4:2025 describes an eXtensible Markup Language (XML) schema for meta-data documenting intellectual property (IP) used in the development, implementation, and verification of electronic systems. This schema provides both a standard method to document IP that is compatible with automated integration techniques and a standard method (generators) for linking tools into a system development framework, enabling a more flexible, optimized development environment. Tools compliant with this standard will be able to interpret, configure, integrate, and manipulate IP blocks that comply with the IP meta-data description. The standard is independent of any specific design processes. It does not cover behavioral characteristics of the IP that are not relevant to integration. This standard enables the creation and exchange of IP in a highly automated design environment.

This document uses a meta-modelling approach to identify commonalities among ten smart manufacturing reference models. Each reference model is placed into the context of the meta-model to facilitate analysis of both common and distinct features. Major smart manufacturing reference model topics are identified, and the reference models compared within each topic. As part of the meta-modelling approach development, a collection of models differing in extent of abstraction characterizes the evolution of a particular smart manufacturing system from the meta-model through a unifying smart manufacturing reference model and successively less abstract domain models to a model for system implementation. This document presents a range of issues and challenges for further work to specify a high-level smart manufacturing reference model that unifies the concepts and practices identified using the meta-model approach analysis of the smart manufacturing reference models.

IEC 62541-15:2025 describes a safety communication layer (services and a protocol) for the exchange of SafetyData using IEC 62541 mechanisms. It identifies the principles for functional safety communications defined in IEC 61784‑3 that are relevant for this safety communication layer. This safety communication layer is intended for implementation in safety devices only.
NOTE 1 This document targets controller-to-controller communication. However, easy expandability to other use-cases (e.g. OPC UA field level communication) has already been considered in the design of this document.
NOTE 2 This document does not cover electrical safety and intrinsic safety aspects. Electrical safety relates to hazards such as electrical shock. Intrinsic safety relates to hazards associated with potentially explosive atmospheres.
This document defines mechanisms for the transmission of safety-relevant messages among participants within a network using OPC UA technology in accordance with the requirements of the IEC 61508 series and IEC 61784-3 for functional safety. These mechanisms can be used in various industrial applications such as process control, manufacturing, automation, and machinery.
This document provides guidelines for both developers and assessors of compliant devices and systems.
NOTE 3 The resulting SIL claim of a system depends on the implementation of this document within the system – implementation of this document in a standard device is not sufficient to qualify it as a safety device.
