IEC 63489:2025 specifies the definition of cross-domain product data concepts (classes and properties) in the context of smart manufacturing.
This document will be published as a set of concepts within cross-domain data dictionary "General Items (IEC 61360-7)” in the IEC CDD.

IEC 63297:2025 provides a classification of NILM sensing devices for use in NILM systems, according to the state of the art of NILM technologies.

IEC 62453-1:2025 is available as IEC 62453-1:2025 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 62453-1:2025 presents an overview and guidance for the IEC 62453 series. It
• explains the structure and content of the IEC 62453 series (see Clause 5);
• provides explanations of some aspects of the IEC 62453 series that are common to many of the parts of the series;
• describes the relationship to some other standards;
• provides definitions of terms used in other parts of the IEC 62453 series.
This third edition cancels and replaces the first edition published in 2016. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) introduction of a new implementation technology (defined in IEC TS 62453-43);
b) introduction of an OPC UA information model for FDT (defined in IEC 62453-71).

IEC 61496-3:2025 specifies additional requirements for the design, construction and testing of non‑contact electro-sensitive protective equipment (ESPE) designed specifically to detect persons or parts of persons as part of a safety-related system, employing active opto-electronic protective devices responsive to diffuse reflection (AOPDDRs) for the sensing function. Special attention is directed to requirements which ensure that an appropriate safety-related performance is achieved. An ESPE can include optional safety-related functions, the requirements for which are given both in Annex A of this document and in Annex A of IEC 61496‑1:2020.
NOTE "Non-contact" means that physical contact is not required for sensing.
This document does not specify the dimensions or configurations of the detection zone and its disposition in relation to hazardous parts for any particular application, nor what constitutes a hazardous state of any machine. It is restricted to the functioning of the ESPE and how it interfaces with the machine.
AOPDDRs are devices that have either
- one or more detection zone(s) specified in two dimensions (AOPDDR-2D), or
- one or more detection zone(s) specified in three dimensions (AOPDDR-3D)
wherein radiation in the near infrared range is emitted by an emitting element(s). When the emitted radiation impinges on an object (for example, a person or part of a person), a portion of the emitted radiation is reflected to a receiving element(s) by diffuse reflection. This reflection is used to determine the position of the object.
Opto-electronic devices that perform only a single one-dimensional spot-like distance measure­ment, for example, optical proximity switches, are not covered by this document.
This document is limited to ESPE that do not require human intervention for detection. It is limited to ESPE that detect objects entering into or being present in a detection zone(s).
This document does not address those aspects required for complex classification or differentiation of the object detected.
This document does not address requirements and tests for outdoor application.
Excluded from this document are AOPDDRs employing radiation with the peak of wavelength outside the range 820 nm to 1 100 nm, and those employing radiation other than that generated by the AOPDDR itself. For sensing devices that employ radiation of wavelengths outside this range, this document can be used as a guide. This document is relevant for AOPDDRs having a minimum detectable object size in the range from 30 mm to 200 mm.
This document can be relevant to applications other than those for the protection of persons, for example, for the protection of machinery or products from mechanical damage. In those applications, different requirements can be appropriate, for example when the materials that are recognized by the sensing function have different properties from those of persons and their clothing.
This document does not deal with electromagnetic compatibility (EMC) emission requirements.

- control equipment which have as their intended use the command and control of machines, automated manufacturing and industrial processes, e.g. discrete and continuous control.
Components of the above named equipment and in the scope of this standard are e.g.:
- (auxiliary) stand-alone power supplies;
- peripherals such as digital and analogue I/O,
- remote-I/O;
- industrial network equipment, embedded or standalone (e.g. switches, routers, wireless base station).
Control equipment and their associated peripherals are intended to be used in an industrial environment and may be provided as OPEN or ENCLOSED EQUIPMENT.
NOTE 1 Control equipment intended also for use in other environments or for other purposes (example: for use in building installations to control light or other electrical installations, or for use on cars, trains or ships) can have additional conformity requirements defined by the safety standard(s) for these applications. These requirements can involve as example: insulation, spacings and power restrictions.
NOTE 2 Computing devices and similar equipment within the scope of IEC 60950 (planned to be replaced by IEC 62368) and conforming to its requirements are considered to be suitable for use with control equipment within the scope of this standard. However, some of the requirements of IEC 60950 for resistance to moisture and liquids are less stringent than those in IEC 61010-1:2010, 5.4.4 second paragraph.
Control equipment covered in this standard is typically intended 237 for use in OVERVOLTAGE CATEGORY II (IEC 60664-1) in low-voltage installations, where the RATED equipment supply voltage does not exceed AC. 1 000 V r.m.s. (50/60 Hz), or DC 1 000 V.

IEC 61784-3-19:2024 specifies a safety communication layer (services and protocol) based on IEC 61784‑1-19, IEC 61784-2-19 and the IEC 61158 series (Type 24 and Type 27). 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 It 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 distributed network using fieldbus technology in accordance with the requirements of the IEC 61508 series 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 2 The resulting SIL claim of a system depends on the implementation of the selected functional safety communication profile within this system – implementation of a functional safety communication profile according to this document in a standard device is not sufficient to qualify it as a safety device.

IEC 61557-14:2023 defines special requirements for test and measurement equipment used to determine the electrical safety of electrical equipment of machinery in accordance with IEC 60204-1.

IEC 62443-2-1:2024 specifies asset owner security program (SP) policy and procedure requirements for an industrial automation and control system (IACS) in operation. This document uses the broad definition and scope of what constitutes an IACS as described in IEC TS 62443‑1‑1. In the context of this document, asset owner also includes the operator of the IACS.
This document recognizes that the lifespan of an IACS can exceed twenty years, and that many legacy systems contain hardware and software that are no longer supported. Therefore, the SP for most legacy systems addresses only a subset of the requirements defined in this document. For example, if IACS or component software is no longer supported, security patching requirements cannot be met. Similarly, backup software for many older systems is not available for all components of the IACS. This document does not specify that an IACS has these technical requirements. This document states that the asset owner needs to have policies and procedures around these types of requirements. In the case where an asset owner has legacy systems that do not have the native technical capabilities, compensating security measures can be part of the policies and procedures specified in this document.
This edition includes the following significant technical changes with respect to the previous edition:
a) revised requirement structure into SP elements (SPEs),
b) revised requirements to eliminate duplication of an information security management system (ISMS), and
c) defined a maturity model for evaluating requirements.

IEC 63082-2:2024 specifies requirements and recommendations for establishing and maintaining intelligent device management (IDM) as outlined in IEC TR 63082-1 in an enterprise having one or more facilities.
The following topics are included in the scope of this document:
- optimizing functionality and performance of intelligent devices for their use;
- managing information related to IDM;
- integrating intelligent devices into industrial automation and control systems (IACS) in facilities;
- exchanging information between stakeholders that achieve and sustain IDM;
- coordinating multiple asynchronous IDM life cycles.

IEC 61987-32:2024 This part of IEC 61987 provides an operating list of properties (OLOP) for the description of the operating parameters and the collection of requirements for I/O modules and a device list of properties (DLOP) for the description of a range of I/O module types.
The structures of the OLOP and the DLOPs correspond to the general structures defined in IEC 61987-11 and agree with the fundamentals for the construction of LOPs defined in IEC 61987-10.
Aspects other than the OLOP, needed in different electronic data exchange processes and described in IEC 61987-10 and IEC 61987-11, are published in IEC 61987-92.
The locations of the libraries of properties and of blocks used in the LOPs concerned are listed in Annex C and Annex D.

This part of IEC 62443 specifies a scheme for defining (selecting, writing, drafting, creating) IEC 62443 security profiles.
This scheme and its specified requirements apply to IEC 62443 security profiles which are planned to be published as part of the upcoming IEC 62443 dedicated security profiles subseries.
IEC 62443 security profiles can support interested parties (e.g. during conformity assessment activities) to achieve comparability of assessed IEC 62443 requirements.

IEC 61406-2:2024 complements IEC 61406-1 by providing additional requirements for those cases where data elements are encoded within the Structured Identification Link string with standardized syntax and semantics.
In addition, this document covers cases where the uniqueness relates to product types/models or lots/batches. The default assumption is that the Identification Link identifies unique objects such as unique serialized products, assets, persons or packages, unless otherwise identified.

This document defines the structure of a standardized digital representation of an asset, called Asset Administration Shell. The Asset Administration Shell gives uniform access to information and services.
The purpose of the Asset Administration Shell is to enable two or more software applications to exchange information and to mutually use the information that has been exchanged in a trusted and secure way.
This document focusses on Asset Administration Shells representing assets of manufacturing enterprises including products produced by those enterprises and the full hierarchy of industrial equipment. It defines the related structures, information, and services.
The Asset Administration Shell applies to:
- any type of industrial process (discrete manufacturing, continuous process, batch process, hybrid production);
- any industrial sector applying industrial-process measurement, control and automation;
- the entire life cycle of assets from idea to end of life treatment;
- assets which are physical, digital, or intangible entities.

IEC 61784-5-8:2024 is available as IEC 61784-5-8:2024 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

This information is given for the convenience of users of this document and does not constitute an endorsement by IEC of the trademark holder or any of its products. Compliance to this profile does not require use of the trade name. Use of the trade name requires permission of the trade name holder.

IEC 62443-2:2023 specifies a comprehensive set of requirements for security-related processes that IACS service providers can offer to the asset owner during integration and maintenance activities of an Automation Solution. Because not all requirements apply to all industry groups and organizations, Subclause 4.1.4 provides for the development of "profiles" that allow for the subsetting of these requirements. Profiles are used to adapt this document to specific environments, including environments not based on an IACS.
NOTE 1 The term "Automation Solution" is used as a proper noun (and therefore capitalized) in this document to prevent confusion with other uses of this term. Collectively, the security processes offered by an IACS service provider are referred to as its Security Program (SP) for IACS asset owners. In a related specification, IEC 62443-2-1 describes requirements for the Security Management System of the asset owner.
NOTE 2 In general, these security capabilities are policy, procedure, practice and personnel related. Figure 1 illustrates the integration and maintenance security processes of the asset owner, service provider(s), and product supplier(s) of an IACS and their relationships to each other and to the Automation Solution. Some of the requirements of this document relating to the safety program are associated with security requirements described in IEC 62443-3-3 and IEC 62443-4-2.
NOTE 3 The IACS is a combination of the Automation Solution and the organizational measures necessary for its design, deployment, operation, and maintenance.
NOTE 4 Maintenance of legacy system with insufficient security technical capabilities, implementation of policies, processes and procedures can be addressed through risk mitigation.
