IEC 62217:2025 is applicable to polymeric insulators for AC systems with a nominal voltage greater than 1 000 V (frequency less than 100 Hz) and DC systems with a nominal voltage greater than 1 500 V whose insulating body consists of one or various organic materials. Polymeric insulators covered by this document are intended for use both on HV overhead lines and in substations, in both indoor and outdoor applications. They include composite insulators with solid and hollow core and resin insulators. Hybrid insulators with ceramic core and polymeric housing are also included, while coated insulators (e.g. with RTV silicone rubber coatings) are not included in this standard. Electrical tests described in this document are done under AC voltage and are in general applicable to insulators to be used in DC systems too. Tests under DC voltage are intended to reflect up-to-date knowledge and experience. Only polymeric housing materials of hybrid insulators are specified in this document. Tests for core materials and the interfaces between housing and core of hybrid insulators are not included.
The object of this document is
- to define the common terms used for polymeric insulators;
- to prescribe common test methods for design tests on polymeric insulators;
- to prescribe acceptance or failure criteria, if applicable;
These tests, criteria and recommendations are intended to ensure a satisfactory lifetime under normal operating and environmental conditions. This document includes design tests intended to reject materials or designs which are inadequate under normal operating and environmental conditions. This document defines test methods and acceptance criteria. The applicable tests are given in the relevant product standard. This third edition cancels and replaces the second edition published in 2012. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:

This document describes the key actors in the eCall chain of service provision in hybrid circuit switched/packet switched network environments as:
1) In-Vehicle System (IVS)/vehicle,
2) Mobile Network Operator (MNO),
3) Public Safety Answering Point (PSAP),
and to provide conformance tests for actor groups 1) – 3).
NOTE 1 Conformance tests are not appropriate nor required for vehicle occupants, although they are the recipients of the service.
NOTE 2 Third party eCall systems (TPS-eCall) are not within the scope of this document. This is because the core TPS-eCall standard (EN 16102) does not specify the communications link between the vehicle and the TPS service provider.
NOTE 3 These conformance tests are partly based on the appropriate conformance tests from EN 16454 and EN 17240. This deliverable therefore adapts and revises Conformance Test Procedures (CTPs) from EN 16454 and EN 17240 for hybrid circuit switched/packet switched network environments.

This document specifies the continuous drop test apparatus and associated test method for the reproducible production of dust from a bulk material under standard conditions, and the measurement of the inhalable and respirable dustiness mass fractions, with reference to existing documents, where relevant (see Clause 6).
The continuous drop method intends to simulate dust generation processes where there are continuous falling operations (conveying, discharging, filling, refilling, weighing, sacking, metering, loading, unloading etc.) and where dust is liberated by winnowing during falling. It can be modified to measure the thoracic fraction as well, but this modification is not specified in this document. It differs from the rotating drum method presented in EN 15051-2 [4] in that in this document, the bulk material is dropped only once, but continuously, while in EN 15051-2, the same bulk material is repeatedly dropped.
Furthermore, this document specifies the environmental conditions, the sample handling and analytical procedures and the method of calculating and presenting the results. A categorization scheme for dustiness is specified, to provide a standardized way to express and communicate the results to users of the bulk materials.
This document is applicable to powdered, granular or pelletised bulk materials.
This document does not apply to test the dust released when solid bulk materials are mechanically treated (e.g. cut, crushed).

This document defines universal and specialized characteristics of health terminological resources that make them fit for the purposes required of various applications. It covers only terminological resources that are primarily designed to be used for clinical concept representation or to those parts of other terminological resources designed to be used for clinical concept representation.
This document helps users to assess whether a terminology has the characteristics or provides the functions that will support their specified requirements. In order to do that, this document focuses on defining characteristics and functions of terminological resources in healthcare that can be used to identify different types of terminological resources for categorization purposes.
NOTE 1        Categorization of healthcare terminological systems according to the name of the system might not be helpful and has caused confusion in the past.
The following aspects are not covered in this document:
—     evaluations of terminological resources;
—     health service requirements for terminological resources and evaluation criteria based on the characteristics and functions;
—     the nature and quality of mappings between different terminologies;
NOTE 2        It is unlikely that a single terminology will meet all the terminology requirements of a healthcare organization: some terminology providers produce mappings to administrative or classification systems such as the International Classification of Diseases (ICD). The presence of such maps would be a consideration in the evaluation of the terminology.
—     the nature and quality of mappings between different versions of the same terminology;
NOTE 3        To support data migration and historical retrieval, terminology providers can provide maps between versions of their terminology. The presence of such maps would be a consideration in the evaluation of the terminology.
—     terminology server requirements and techniques and tools for terminology developers;
—     characteristics for computational biology terminology.

This document specifies test methods for the determination of the chemical compatibility of packaging/ IBC made from polyethylene (PE), fluorinated polyethylene and co-extruded plastics. It covers the determination of adequate plastics compatibility against the following processes of deterioration:
—     softening due to absorption (swelling);
—     stress cracking;
—     combinations thereof.
This document is applicable to:
—     drums and jerricans made from plastics;
—     composite packaging (plastics) with inner receptacle made from plastics;
—     rigid plastics IBCs (types 31H1 and 31H2);
—     composite IBCs with rigid plastics inner receptacles (type 31HZ1);
used for the transport of liquid dangerous goods.
Proof of adequate plastics compatibility obtained using the test procedures specified in this document is only applicable to the above packaging and IBC types of the following materials and material specifications:
—     packaging and IBCs made from PE;
—     packaging and IBCs made from PE, whose internal surfaces are fluorinated; and
—     packaging and IBCs which are coextrusion blow moulded and have walls with the following multilayer structure (from inside to outside):
—    polyamide (PA), bonding agents, PE, or
—    ethylene vinyl alcohol (EVOH), bonding agents, PE.
Note              Packaging and IBCs made from PE and packaging and IBCs made from PE with fluorinated internal surfaces, deteriorate additionally due to molecular degradation reactions with the corresponding packaged substances. For this, the chemical compatibility can also be verified by the type tests described in ISO 13274:2013, Annex B, B.2.3, using the standard liquid nitric acid (55 %) or appropriate original packaged substances. Packaging made from Coex PE/PA and Coex PE/EVOH is not resistant to polar acid molecularly degrading substances such as nitric acid, with the result that a corresponding method is not considered for this process of deterioration in this document.

NOTE 1   For detailed information about the electrical/electronic requirements for driverless trucks see EN ISO 3691-4:2023, 4.1.3.
NOTE 2   Reference is made to this document in other standards which cover the non-electrical requirements of the various industrial truck types.
This document deals with safety requirements for all electrical and electronic components of industrial trucks, including electrically actuated hydraulic/pneumatic valves. It specifies minimum performance levels required for safety functions realized by safety related parts of control systems. It is intended to be used to avoid or minimize hazards or hazardous situations listed in Annex I. These situations can arise during the operation in the area of use for which it is designed and during maintenance of trucks in accordance with the specifications and instruction given by the manufacturer.
This document does not deal with hazards which could occur:
-   during construction;
-   when operating in potentially explosive atmospheres;
-   because of malfunction of non-electric safety-related parts of control systems, e.g. hydraulic and pneumatic elements like pistons, non-electric valves, pumps, etc.;
-   when operating outside the range of 30 % to 95 % (not condensing) of relative humidity.
NOTE 3   The level of the defined required performance for electrical safety related control systems can be used as a guideline to determine the performance of non-electric systems.
NOTE 4   Hazards due to penetration of water and dust are covered by the definition of PLr of safety functions, according to EN ISO 13849-1:2023.
NOTE 5   Safety measures outside the scope of the electrical/electronic system are covered by other safety standards e.g. EN ISO 3691 series and EN 16307 series.

This document specifies the environmental conditions, the sample handling and analytical procedures and the method of calculating and presenting the results. Reasons are given for the need for more than one method and advice is given on the choice of method to be used.
This document establishes a categorization scheme for dustiness to provide a standardized way to express and communicate the results to users of the bulk materials. Details of the scheme for each method are given in EN 15051-2:2025 and EN 15051-3:2025.
This document is applicable to powdered, granular or pelletized bulk materials.
This document does not apply to test the dust released during mechanical reduction of solid bulk materials (e.g. cut, crushed) or to test application procedures for the bulk materials.

This document specifies the requirements and general principles governing the biological evaluation of medical devices within a risk management process according to ISO 14971.
This document applies to the biological evaluation of medical devices that have direct contact or indirect contact with either:
—     a patient's body during intended use or reasonably foreseeable misuse; or
—     the body of other users who are not patients, if the medical device is intended for personal protection (e.g. medical gloves, surgical masks).
Biological evaluation assesses the biological safety of the medical device by considering the biological risks associated with:
—     constituents of a medical device; and
—     tissue-device interactions (including physical effects).
The biological evaluation specified in this document can address the biological safety of the medical device, considering the life cycle from design and development through initial use of the finished medical device to final decommissioning or withdrawal from use. The biological evaluation considers both the biological safety of the finished device in first use, and the significance of any changes to the medical device which can occur throughout the life cycle. However, the evaluation of risks related to environmental impacts of decommissioning of medical devices are not within the scope of this document. This document does not mandate re-testing of medical devices that are already on the market and have established and acceptable safety profiles (see 6.6.2).
This document can be useful to support clinical or usability evaluations of medical devices. For example, a biological evaluation is a pre-requisite for conducting a clinical trial. This means that principles outlined in this document can be applied to the evaluation of prototype or development stage devices, as well as to finished medical devices.
Other parts of the ISO 10993 series cover specific aspects of biological evaluation, such as chemical characterization, biological testing, sample preparation, animal welfare and toxicological risk assessment.
For some types of medical devices, specific requirements from other standards (outside the ISO 10993 series) can be considered with a justification for the approach taken if there are differences between the requirements of the ISO 10993 series and those provided in other standards. For example, the ISO 18562 series provides specific requirements for biological evaluation of breathing gas pathway medical devices and ISO 7405 provides specific requirements for biological evaluation of dental devices.
The evaluation of risks related to infectious agents [e.g. bacteria, moulds, yeasts, viruses, transmissible spongiform encephalopathy (TSE) agents] is not within the scope of this document.
NOTE 1        The evaluation of bacterial endotoxins is addressed by ISO 11737-3.
NOTE 2        The evaluation of risks related to viruses, TSE agents and other pathogens originating from materials of animal origin is addressed by the ISO 22442 series.

This document is applicable to the following groups of machines, auxiliary equipment and their combinations:
-   palletizers;
-   depalletizers;
-   auxiliary equipment incorporated in or linked to the operations of palletizers and depalletizers;
-   conveying systems which are part of palletizers or depalletizers;
-   palletizers combined with functions of machines which are covered by other parts of EN 415, but detailed requirements are only provided for palletizing functions.
The individual machines are described in 3.2. Auxiliary equipment is described in 3.3.
This document deals with safety requirements for machine design, transport, installation, commissioning, operation, adjustment, maintenance and cleaning of palletizers, depalletizers, auxiliary equipment and conveying systems which are part of palletizer or depalletizer. The extent to which hazards, hazardous situations and events are covered is indicated in Annex A.
Exclusions:
This document is not applicable to the following machines:
-   machines that were manufactured before the date of publication of this document by CEN;
-   conveyors that connect palletizers and depalletizers with machines that are not in the scope of this document.
Conveyors in the scope of this document also fall in the scope of EN 619:2022, however, this document describes the additional or specific hazards for conveyors fitted into palletizers and depalletizers and so the requirements of this document take precedence over the requirements of EN 619:2022.
This document does not consider the following hazards:
—   the use of palletizers and depalletizers in a potentially explosive atmosphere;
—   the health, safety or hygiene hazards associated with the products that are contained in the unit load handled by palletizers and depalletizers except for the spillage of hazardous substances caused by the malfunction of a machine.

IEC 60072-2: 2025 covers the majority of rotating electrical machines for industrial purposes within the dimension range and output powers:
- Foot-mounted: shaft heights: 355 mm to 1 000 mm.
- Flange-mounted: pitch circle diameter of flange: 1 180 mm to 2 360 mm.
It gives tables of fixing dimensions, shaft extension dimensions and their tolerances. However, the variety of construction and the wide range of applications for the large machines with shaft heights above 315 mm have led to the establishment of a relatively large number of values for the dimension in order to cover all possible constructions. Owing to this, the present part covers a wider range than IEC 60072-1 within which range values suitable for all designs or for a more detailed standardization can be chosen. NOTE The mounting dimensions given in this document for shaft heights 355 mm and 400 mm have been chosen from values given in IEC 60072-1.
This second edition cancels and replaces the first edition published in 1990. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) complete revision on the basis of IEC 60072-1;
b) additional tolerances and measurements for shafts and flanges (DIN SPEC 42955).

This document specifies the rotating drum test apparatus and associated test method for the
reproducible production of dust from a bulk material under standard conditions, and the measurement
of the inhalable, thoracic and respirable dustiness mass fractions, with reference to existing European
standards, where relevant (see Clause 6).
This method is suitable for general bulk material handling processes, including all those processes where
the bulk material is dropped, or can be dropped. It differs from the continuous drop method presented in EN 15051-3:2025 [4]. In EN 15051-2:2025 the same bulk material is repeatedly dropped, whilst in EN 15051-3:2025, the bulk material is dropped only once, but continuously.
Furthermore, this document specifies the environmental conditions, the sample handling and analytical procedures, and the method of calculating and presenting the results. A categorization scheme for dustiness is specified, to provide a standardized way to express and communicate the results to users of the bulk materials.
This document is applicable to powdered, granular or pelletized bulk materials. A standard sample volume is used.
This document does not apply to test the dust released when solid bulk materials are mechanically reduced (e.g. cut, crushed).

This document specifies the measurement of strain by means of strain gauges and strainmeters carried out for geotechnical monitoring. General rules of performance monitoring of the ground, of structures interacting with the ground, of geotechnical fills and of geotechnical works are presented in ISO 18674-1.
This document is applicable to:
—     performance monitoring of
—    1-D structural members such as piles, struts, props and anchor tendons;
—    2-D structural members such as foundation plates, sheet piles, diaphragm walls, retaining walls and shotcrete/concrete tunnel linings;
—    3-D structural members such as gravity dams, earth- and rock-fill dams, embankments and reinforced soil structures;
—     checking geotechnical designs and adjustment of construction in connection with the observational design procedure;
—     evaluating stability during or after construction.
With the aid of a stress-strain relationship of the material, strain data can be converted into stress and/or forces (for 1-D members; see ISO 18674-8) or stresses (for 2-D and 3-D members, see ISO 18674-5).
NOTE            This document fulfils the requirements for the performance monitoring of the ground, of structures interacting with the ground and of geotechnical works by the means of strain measuring instruments as part of the geotechnical investigation and testing in accordance with References [1] and [2].

This document specifies the minimum characteristics of instruments for measuring physical quantities characterizing an environment, as well as the methods for measuring the physical quantities of this environment.

This document prescribes:
—     how to document a use case with an associated business context and exchange requirements;
—     a methodology to identify and specify the information exchanges required at identified times during the life cycle of assets.
This document presents the information delivery manual (IDM) in natural language terms to facilitate interoperability between software applications used during all phases of the life cycle of assets (both buildings and infrastructure). It promotes digital collaboration between actors within the identified business context and provides a basis for accurate, reliable, repeatable and high-quality information exchange.
The information delivery manual (IDM) methodology specified in this document can be applied to any information management trigger event to identify the details of the information required to be exchanged.

This document specifies a static test method for measuring the strength of a conveyor belt mechanical fastening; the mechanical joints can be either of the type employing a connecting rod or of a type which does not employ a connecting rod.
This document does not cover vulcanized joints.
This document is neither applicable to nor valid for light conveyor belts, as described in ISO 21183-1.
NOTE            The purpose of the test specified in this document is to eliminate mechanical fastenings of insufficient static strength. It is intended to establish a dynamic test at a later date.

This document supplements or modifies the corresponding clauses in IEC 62841-1, so as to convert it into the IEC Standard: Particular requirements for hand-held jointers. IEC 62841-1:2014, Clause 1 is applicable, except as follows: This document applies to hand-held jointers for cutting into wood or materials with similar physical characteristics such as, for example, chipboard, fibreboard and plywood.

This document specifies the identification of radionuclides and the measurement of their activity in soil using in situ gamma spectrometry with portable systems equipped with germanium or scintillation detectors.
This document is suitable to rapidly assess the activity of artificial and natural radionuclides deposited on or present in soil layers of large areas of a site under investigation.
This document can be used in connection with radionuclide measurements of soil samples in the laboratory (see ISO 18589-3) in the following cases:
—     routine surveillance of the impact of radioactivity released from nuclear installations or of the evolution of radioactivity in the region;
—     investigations of accident and incident situations;
—     planning and surveillance of remedial action;
—     decommissioning of installations or the clearance of materials.
It can also be used for the identification of airborne artificial radionuclides, when assessing the exposure levels inside buildings or during waste disposal operations.
Following a nuclear accident, in situ gamma spectrometry is a powerful method for rapid evaluation of the gamma activity deposited onto the soil surface as well as the surficial contamination of flat objects.
NOTE            The method described in this document is not suitable when the spatial distribution of the radionuclides in the environment is not precisely known (influence quantities, unknown distribution in soil) or in situations with very high photon flux. However, the use of small volume detectors with suitable electronics allows measurements to be performed under high photon flux.

The ISO 11929 series specifies a procedure, in the field of ionizing radiation metrology, for the calculation of the “decision threshold”, the “detection limit” and the “limits of the coverage interval” for a non-negative ionizing radiation measurand when counting measurements with preselection of time or counts are carried out. The measurand results from a gross count rate and a background count rate as well as from further quantities on the basis of a model of the evaluation. In particular, the measurand can be the net count rate as the difference of the gross count rate and the background count rate, or the net activity of a sample. It can also be influenced by calibration of the measuring system, by sample treatment and by other factors.
ISO 11929 has been divided into four parts covering elementary applications in this document, advanced applications on the basis of the ISO/IEC Guide 3-1 in ISO 11929-2, applications to unfolding methods in ISO 11929-3, and guidance to the application in ISO 11929-4.
This document covers basic applications of counting measurements frequently used in the field of ionizing radiation metrology. It is restricted to applications for which the uncertainties can be evaluated on the basis of the ISO/IEC Guide 98-3 (JCGM 2008). In Annex A, the special case of repeated counting measurements with random influences is covered, while measurements with linear analogous ratemeters are covered in Annex B.
ISO 11929-2 extends the former ISO 11929:2010 to the evaluation of measurement uncertainties according to the ISO/IEC Guide 98-3:2008/Suppl 1:2008. ISO 11929-2 also presents some explanatory notes regarding general aspects of counting measurements and on Bayesian statistics in measurements.
ISO 11929-3 deals with the evaluation of measurements using unfolding methods and counting spectrometric multi-channel measurements if evaluated by unfolding methods, in particular, for alpha- and gamma‑spectrometric measurements. Further, it provides some advice on how to deal with correlations and covariances.
ISO 11929-4 gives guidance to the application of the ISO 11929 series, summarizes shortly the general procedure and then presents a wide range of numerical examples. Information on the statistical roots of ISO 11929 and on its current development may be found elsewhere[33][34].
The ISO 11929 series also applies analogously to other measurements of any kind especially if a similar model of the evaluation is involved. Further practical examples can be found, for example, in ISO 18589[1], ISO 9696[2], ISO 9697[3], ISO 9698[4], ISO 10703[5], ISO 7503[6], ISO 28218[7] and ISO 11665[8].
