ICS 25 is a classification code in the International Classification for Standards (ICS) system. It covers "MANUFACTURING ENGINEERING". The ICS is a hierarchical classification system used to organize international, regional, and national standards, facilitating the search and identification of standards across different fields.
There are 13011 standards classified under ICS 25 (MANUFACTURING ENGINEERING). These standards are published by international and regional standardization bodies including ISO, IEC, CEN, CENELEC, and ETSI.
The International Classification for Standards (ICS) is a hierarchical classification system maintained by ISO to organize standards and related documents. It uses a three-level structure with field (2 digits), group (3 digits), and sub-group (2 digits) codes. The ICS helps users find standards by subject area and enables statistical analysis of standards development activities.

IEC 62541-24:2026 specifies an OPC UA information model to expose information, at what dates and times specific actions are executed by the OPC UA Server. Those schedules can optionally also be manipulated via the information model.
The schedule defines on which dates they are active, and can also reference global calendars representing specific dates, for example public holidays. In addition, the schedule defines times and actions that will be executed at that time. The model defines writing Variables and calling Methods but can be extended to other actions as well.
The NamespaceUri for all NodeIds defined in this document is defined in Annex A.

IEC TS 63283-2: 2025 has the goal of analyzing the impact of smart manufacturing on the daily operation of an industrial facility. It focusses on the perspective of automation and control of the production system, but also on the supporting processes of ordering, supply chain management, design, engineering and commissioning, operational technology, life cycle management, maintenance management, and resource management.
These recommendations are accomplished on the basis of several carefully selected use cases that are familiar to manufacturing industry. Therefore, each use case is described, followed by an analysis of the possible influence of smart manufacturing and the assessment of the impact on existing and future standardization.
This first edition cancels and replaces the first edition of IEC TR 63283-2 published in 2022. This edition constitutes a technical revision.

IEC PAS 62443-1-6:2025 introduces new communication channels, a new organization of functions, and new cybersecurity concerns. Asset owners are looking for more guidance in how to deal with all these changes. The IEC 62443 series, Security for industrial automation and control systems, can be applied to this new technology, but many asset owners look at the scope of the series and wonder where to start.
This part of IEC 62443 seeks to give guidance to asset owners and their service providers on how the IEC 62443 series can be used to address IIoT. The document points to requirements in the different parts of the IEC 62443 series that might be helpful to the asset owner as they both consider implementing IIoT in their automation solutions as well as dealing with existing IIoT. Product suppliers and service providers can find this document useful as well.
NOTE The drafting committee for IEC 62443 is currently engaged in revision of parts of the standard to recognize emerging technologies, such as IIoT, and this document is part of that on-going effort.
NOTE In accordance with ISO/IEC Directives, Part 1, IEC PASs are automatically withdrawn after 4 years.

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.
This second edition cancels and replaces the first edition published in 2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect 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 specifies requirements for electroplated coatings of zinc with supplementary treatments using hexavalent chromium compounds on iron or steel. It includes information to be supplied by the purchaser to the electroplater, and the requirements for heat treatment before and after electroplating.
This document is not applicable to zinc coatings applied:
— to sheet, strip or wire in the non-fabricated form;
— to close-coiled springs;
— for purposes other than protective and decorative.
This document does not specify requirements for the surface condition of the basis metal prior to electroplating with zinc. However, defects in the surface of the basis metal can adversely affect the appearance and performance of the coating.
The coating thickness that can be applied to threaded components can be limited by dimensional requirements, including class or fit.

IEC 61326-2-7:2025 specifies the EMC test requirements for process automation equipment using at least one Ethernet APL (Ethernet ADVANCED PHYSICAL LAYER) compliant port according IEC TS 63444. The type of equipment covered by this document includes INFRASTRUCTURE DEVICES such as switches as well as measurement and control devices. This document provides requirements for the EMC test setups of the APL interface for devices intended for use in process control and process measurement.
The other functions of the equipment remain covered by other parts of the IEC 61326 series.
NOTE Ethernet-APL uses IEEE Std. 802.3 2022 Ethernet Physical Layer 10BASE-T1L, suitable to be used for full-duplex communication over a single balanced pair of conductors.
The test levels are based on the intended environment as stated in the product’s specification or user documentation and selected appropriately from IEC 61326-1.
