This document specifies principles for determination of the thickness of metallic and non-metallic materials using the contact technique or immersion technique, based on measurement of the time of flight of ultrasonic pulses only.

This document describes the introduction of radiated immunity testing for the components and vehicles equipped with V2X communications. The link communication connection and V2X scenario simulation are considered to make the V2X functions and their communications operate normally during the immunity testing. Examples of monitoring are also discussed to show the electromagnetic interference reactions of the device with V2X under test. In addition, test hints are described to provide information on radiated immunity for V2X. Technical specifications are not within the scope of this document.

This document specifies the requirements for secured and unsecured diagnostic communication between a client DoIP entity and server(s) installed in the vehicle using Internet protocol (IP) as well as the transmission control protocol (TCP) and user datagram protocol (UDP). This includes the definition of vehicle gateway requirements (e.g. for integration into an existing computer network) and test equipment (client DoIP entity) requirements (e.g. to detect and establish communication with a vehicle). This document specifies features that are used to detect a vehicle in a network and enable communication with the vehicle gateway as well as with its subcomponents during the various vehicle states. These features are separated into two types: mandatory and optional. This document specifies the following mandatory features: — vehicle network integration (IP address assignment); — vehicle announcement and vehicle discovery; — vehicle basic status information retrieval (e.g. diagnostic power mode); — connection establishment (e.g. concurrent communication attempts), connection maintenance and vehicle gateway control; — data routing to and from the vehicle's sub-components; — error handling (e.g. physical network disconnects). This document specifies the following optional features: — DoIP entity status monitoring; — transport layer security (TLS); — DoIP entity firewall capabilities.

This document gives guidance on the qualification of the performance of a computed tomography (CT) system with respect to various testing tasks. This document is applicable only to industrial imaging (i.e. non-medical applications) and provides a consistent set of definitions of CT performance parameters, including the relationship between these performance parameters and CT system specifications. This document is applicable to industrial computed tomography. This document does not apply to other techniques of tomography such as translational tomography and tomosynthesis.

This document specifies the characteristics of prevailing torque (all metal) hexagon high nuts, in steel and stainless steel, with metric fine pitch thread 8 mm to 39 mm, and with product grades A and B. NOTE These nuts are designed with an overall height hmin = mmin (as specified in ISO 898-2 and ISO 8674 for style 2) plus the prevailing torque feature. hmax has been established in function of hmin; therefore, the tolerance (hmax – hmin) does not follow the ISO code system for tolerances (IT system). The wrenching height mw,min corresponds to the values specified for style 1. If in certain cases other specifications are requested, property classes and stainless steel grades can be selected from ISO 898-2 or ISO 3506-2.

This document specifies a method for testing the immunity of passenger cars and commercial vehicles to electrical disturbances from off-vehicle radiation sources, regardless of the vehicle propulsion system (e.g. spark ignition engine, diesel engine, electric motor). The electromagnetic disturbances considered are limited to continuous narrowband electromagnetic fields. While this document refers specifically to passenger cars and commercial vehicles, generalized as “vehicle(s)”, it can readily be applied to other types of vehicles. ISO 11451-1 specifies general test conditions, definitions, practical use, and basic principles of the test procedure. Function performance status classification guidelines for immunity to electromagnetic radiation from an off-vehicle radiation source are given in Annex A.

This document specifies the characteristics of prevailing torque hexagon regular nuts (with non‑metallic insert), in steel and stainless steel, with metric fine pitch thread 8 mm to 39 mm, and with product grades A and B. NOTE These nuts are designed with an overall height equal to mmin (as specified in ISO 898-2 and ISO 8673 for style 1) plus the prevailing torque feature. The height of the prevailing torque feature (hmax – mmin) for the non-metallic insert is identical for regular, high and thin nuts for a given diameter. If in certain cases other specifications are requested, property classes and stainless steel grades can be selected from ISO 898-2 or ISO 3506-2.

This document specifies a method for laboratory measurement of the pH value of polymer dispersions and coating materials using pH sensors with a glass membrane.

This document specifies the characteristics of prevailing torque hexagon thin nuts (with non‑metallic insert), in steel and stainless steel, with metric coarse pitch thread M3 to M39, and with product grades A and B. NOTE These nuts are designed with an overall height equal to mmin (as specified in ISO 898-2 and ISO 4035 for style 0) plus the prevailing torque feature. The height of the prevailing torque feature (hmax – mmin) for the non-metallic insert is identical for regular, high and thin nuts for a given diameter. Nuts with sizes D WARNING — Thin nuts (style 0) have a reduced loadability compared to regular or high nuts, they are not designed to provide resistance to thread stripping (see ISO 898-2). If in certain cases other specifications are requested, stainless steel grades and property classes can be selected from ISO 3506-2.

IEC 61987-100:2025 provides the semantics of the data needed for the area of process automation, the Industrial Internet of Things (IIoT), and smart manufacturing. Classification and description of products with classes and properties for future objects within the scope of TC 65 (Industrial-process measurement, control and automation) will be developed as IEC 61987 DB standard and published via IEC CDD data dictionary IEC 61987.

This document specifies principles for the design and selection (independent of the nature of the energy source) of interlocking devices associated with guards and provides guidance on measures to minimize the possibility of defeat of interlocking devices in a reasonably foreseeable manner.
This document covers principles for the design, selection and application of the following:
—     parts of the guards which actuate interlocking devices;
—     trapped key interlocking devices and systems for machinery applications.
NOTE            ISO 14120 specifies general requirements for the design and construction of guards provided primarily to protect persons from mechanical hazards. The processing of the signal from the interlocking device to stop the machine and prevent unexpected start up is covered in ISO 14118, ISO 13849-1 and IEC 62061.

This International Standard applies to Source Switching Equipment, hereafter referred to as SSE(s), for household and similar uses, primarily intended to be used for Energy Efficiency purposes with local production and/or storage of energy.
This standard has been drafted following principles of:
- IEC guides 118 and 119 for Energy Efficiency;
- IEC guide 110 for safety.
SSEs are intended to be installed in low voltage prosumer electrical installations (PEI) to deliver the electrical energy:
- either to current-using equipment (direct feeding mode or island mode);
- or to the grid (reverse feeding mode).
SSEs are intended to select and/or combine two power sources (e.g. selected among grid, local power source, storage units) within an Electrical Energy Management system (EEMS). SSEs may also be used for backup supply.
NOTE SSEs capable to select more than two sources are under consideration.
SSEs are part of the fixed electrical installation.
This standard applies to SSEs for operation in:
- AC single or multiphase circuits with rated voltages not exceeding 440 V AC, frequencies of 50 Hz, 60 Hz or 50/60 Hz and rated currents not exceeding 125 A. They are intended to be used in installations with prospective short circuit current not exceeding 25 000 A, or
- DC circuits. SSE for DC circuits are under consideration (next edition).
SSEs may be operated:
- manually (M-SSE), or
- remotely (R-SSE), or
- automatically (A-SSE), or
- a combination of the above methods of operation, e.g. manual and remote.
SSEs are constructed either as Combined-SSEs (C-SSEs, based on dedicated products suc as circuit breakers, switches or contactors) or Non-Combined SSEs (NC-SSEs).
SSEs are intended for use in circuits where protection against electrical shock and over-current according to IEC 60364 is provided, unless the SSE already contains such protective function.
SSEs are normally installed by instructed persons (IEC 60050-195:1998, 195-04-02) or skilled persons (IEC 60050-195:1998, 195-04-01). SSEs are normally used by ordinary persons (IEC 60005-195:1998, 195-04-03) and do not require maintenance.
The requirements of this standard apply for standard environmental 420 conditions as given in clause 7. They are applicable to SSEs intended for use in an environment with pollution degree 2 and overvoltage categories III according to IEC 60664-1:2020. SSEs have at least a degree of protection IP 20 according to IEC 60529. Additional requirements may be necessary for devices used in locations having more severe environmental conditions.
SSEs do not, by their nature, provide an isolation function nor the overcurrent protection. However, isolation and overcurrent protection functions as covered by relevant product standards may be provided by Combined SSEs.
In some countries, it is not permitted to have synchronization of local sources with the grid for particular grid conditions, e.g. when fluctuations of the grid voltage or frequency are outside the tolerance limits.
This document does not apply to transfer switching equipment (TSE) intended to be used by skilled persons, as covered by IEC 60947-6-1:2021.

This document specifies two sets of procedures for conditioning of bituminous mixtures in terms of oxidative ageing. Procedures A.1 and A.2 can be applied on loose bituminous mixture before compaction of specimens, procedures B.1 and B.2 on compacted specimens.
Material conditioned by this document can be used for further testing to assess the effect of oxidative ageing on characteristics of bituminous mixtures and thus on their durability and recyclability. Alternatively, binder can be extracted from conditioned mixture to assess the effect of oxidative ageing on binder characteristics taking into account potential effects of mineral aggregates on ageing.
This document is applicable to bituminous mixtures manufactured in the laboratory or in a mixing plant. Procedures B.1 and B.2 are applicable to specimens from laboratory production or samples taken from the field.

This document specifies requirements for the maximum amount, and in some cases, the maximum concentration of certain substances and mixtures used in experimental sets for chemistry and related activities.
These substances and mixtures are:
-   those classified as hazardous by the EC-legislation applying to hazardous substances and hazardous mixtures [1];
-   substances and mixtures which in excessive amounts could harm the health of the children using them and which are not classified as hazardous by the above-mentioned legislation; and
-   any other chemical substance(s) and mixture(s) delivered with the experimental set.
This document applies to experimental sets for chemistry and related activities including crystal growing sets, carbon dioxide generating experimental sets and supplementary sets. It also covers sets for chemical experiments within the fields of mineralogy, biology, physics, microscopy and environmental science whenever they contain one or more chemical substances and/or mixtures which are classified as hazardous according to Regulation (EC) No. 1272/2008 [1].
This document also specifies requirements for marking, a contents list, instructions for use, eye protection and for the equipment intended for carrying out the experiments.
This document does not apply to combined sets, e.g. a combination of a chemistry set and a crystal growing set. It also does not apply to toys that are covered by EN 71-13 (e.g. cosmetic kits). Requirements for certain other chemical toys are given in EN 71-5.
NOTE   The terms "substance" and "preparation", are used in the "REACH Regulation", Regulation (EC) No. 1907/2006 [2]. According to the Globally Harmonized System (GHS) of classification and labelling of chemicals, which in the European Union has been enacted by Regulation (EC) No. 1272/2008 (classification, labelling and packaging of substances and mixtures) [1], the timetable for the introduction of GHS is followed. The words "preparation" and "mixture" are considered synonymous; both are a mixture or solution of substances that do not react with each other. The old term "preparation" will be replaced by the new term "mixture" in due course. In this document, only the term "mixture" is used.

IEC 61800-9-2:2023 specifies energy efficiency indicators of power electronics (complete drive modules (CDM), input or output sub drive modules (SDM), power drive systems (PDS) and motor starters, all used for motor driven equipment.
This document is a group energy efficiency publication according to IEC Guide 119 and specifies the methodology for the determination of losses of the complete drive module (CDM), the sub drive module (SDM), the power drive system (PDS) and the motor system.
It defines IE and IES classes, their limit values and provides test procedures for the classification of the overall losses of the motor system.
Furthermore, this document proposes a methodology for the implementation of the best energy efficiency solution of drive systems. This depends on the architecture of the motor driven system, on the speed/torque profile and on the operating points over time of the driven load equipment. It provides a link for the energy efficiency evaluation and classification of the extended product.
