This document is applicable to material testing and specifies the requirements for the tensile testing of metallic materials at ambient temperature for aerospace applications.
It is applied when referred to in the EN technical specification or material standard unless otherwise specified on the drawing, order or inspection schedule.

This document specifies the classification of imperfections possibly generated during an additive manufacturing process by PBF-LB (laser beam powder bed fusion) or PBF-EB (electron beam powder bed fusion) for metallic parts.
This document also indicates the most probable causes of the formation of imperfections and includes illustrations.
This can be extended to other additive manufacturing process categories, nevertheless, the indication of probable causes is process specific.
Acceptance criteria and dimensional description or scale for imperfections are not included in this document.

This document specifies equipment and procedures for determining the pull-through resistance of plate and spiral anchors through thermal insulation.

This document specifies terms and definitions applicable to the EN 18000 series and requirements concerning information to be provided by applicants submitting animal health in vitro diagnostic reagents to control.
This document is applicable to diagnostic reagents, as a priority for infectious (bacterial, viral, fungal or parasitic) or prion diseases and associated animal species for which harmonization of practices in this area is necessary, i.e. those for which the national, regional or international regulatory framework provides for the control of trade in animals and/or animal products and/or the definition of a health status (absence of infection) of areas, establishments or individuals. While all reagents designated by the competent authorities fall under the scope of this document, the authorities or any other animal health stakeholder can choose to derogate in specific and exceptional situations such as emerging, exotic or rare diseases.
This document is not applicable to all existing diagnostic reagents, in particular those for which certain parameters described in this document cannot be validly evaluated in accordance with international requirements due, e.g. to the absence of a specific reference method and/or accessible and duly validated reference materials (RMs).
This document does not cover the step in which the user verifies a reagent (analysis method adoption).

This document establishes a normative definition of communication between personal telehealth peak flow monitoring devices (agents) and managers (e.g., cell phones, personal computers, personal health appliances, and set top boxes) in a manner that enables plug-and-play interoperability. It leverages work done in other ISO/IEEE 11073 standards including existing terminology, information profiles, application profile standards. It specifies the use of specific term codes, formats, and behaviors in telehealth environments restricting optionality in base frameworks in favor of interoperability.
This document defines a common core of functionality of a peak-flow monitoring device. The use case is restricted to personal respiratory monitoring and therefore does not include hospital-based spirometry. Continuous and high-acuity monitoring (e.g., for emergency response) are outside the scope of the use case. In the context of personal health devices, a peak flow meter is a device is used to measure the respiratory function of those managing respiratory conditions such as asthma and chronic obstructive pulmonary disease. The ability to identify declining respiratory status prior to the need for acute intervention improves the quality of life for the individual while reducing the overall costs of care. Respiratory status data are collected by a personal respiratory monitoring device and forwarded to a central data repository for review and action by a health care provider. The data are episodic in nature and are forwarded at designated intervals or when the person is symptomatic.

This standard defines an object-oriented abstract information model to represent a PHD and the observations generated by a PHD. It specifies what information needs to be present and the relationships between the informational elements in the model. It models observations in a generic way by focusing on the information content contained in the presentation of health measurements. The modeling follows the practice of ISO/IEEE 11073-20601 [B12] where Unified Modeling Language (UML) is used to describe a set of objects and the relationship between the objects.7 Tables provide descriptions of the attributes in the objects. IEEE 11073-10101™ nomenclature terms are used to express clinical content. This standard provides guidance as to what an exchange protocols needs to communicate to properly represent health observations, but is not, in itself, sufficient to be an exchange protocol. However, the content model defined herein does have sufficient detail to help organizations validate that there is no loss of the semantic content induced by data exchanges in a protocol adhering to this standard. This standard does not define a security framework.

This document provides information security controls, including implementation guidance, for health organizations. It is based on ISO/IEC 27002:2022
In addition to generic ICT equipment and software used in many other environments, the scope of this document includes software and systems specifically for healthcare, such as electronic health record systems and medical devices incorporating health software. Such medical devices can be programmed or programmable and can contain software, firmware or both.
Other digital equipment (such as that for environmental and infection control, building management, and physical security), which can be used in premises where healthcare is provided, is also in scope.
This document applies to information in all its aspects, whatever form the information takes (including text and numbers, sound recordings, drawings, images and video), by whatever means it has been acquired or captured, whatever means are used to store it (such as printing or writing on paper or storage electronically), and whatever means are used to transfer or exchange it (orally, by hand, by post, movement of storage media, direct links or networking).
This document is for organizations of all types and sizes that provide healthcare or are custodians of personal health information for other reasons. The information that they are responsible for can be stored and processed in many possible ways and locations, including on premises or in the cloud, but remains in scope.
This document applies to all physical settings where healthcare is intended to be delivered, such as hospitals, clinics and other locations or facilities designated for healthcare purposes such as ambulances and mobile imaging or diagnostic units. It also applies to care provided elsewhere, such as in residential premises. In addition to the range of settings, this document applies to all methods of service provision including remote or virtual healthcare.

It covers the assessment of the intrinsic performance of barriers that can reasonably be assembled inside the testing facility described in EN ISO 10140-2 and EN ISO 10140-4.
This method is not intended for the determination of the intrinsic characteristics of airborne sound insulation of noise reducing devices to be installed on roads in non-reverberant conditions.

This document specifies a method of testing the fire resistance of "fire-proof" electrical cables.

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 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;

The scope of the present document is to provide the elements needed for elaborating the programme execution logic and drafting the execution plan for the realization of a product.
NOTE 1   In this document, the term “logic” alone is sometimes used for “execution logic”.
NOTE 2   In this document, the term “product” is used to designate the object of the program concerned, and the term “system” is used to designate the product for anything related to system engineering.
NOTE 3   The product is also considered a “system-of-interest” and its enabling systems are also taken into account.
The execution logic and plan enable customers/suppliers to reach an agreement on how their respective processes and activities can be organized.
The aim is to enable each actor in the programme to manage their activities with sufficient visibility of the sequencing of the other stakeholdersʼ activities.
This document belongs to the documents supporting EN 9200 relating to the programme management specification.
The present document describes the principles of programme execution logic and defines the corresponding management requirements. This description is supplemented:
—   on the one hand, in terms of execution logic principles, by:
—   the challenges of a basic logic common to all actors (synchronization);
—   the applicable criteria to set up this basic logic;
—   the translation of this logic into the programme processes;
—   on the other hand, in terms of implementing the execution logic, by:
—   the procedures for practical implementation of the management requirements defined in EN 9200;
—   adaptations of the logic according to the various constraints and specificities of the programme, and justification of these adaptations;
—   the consistency between the basic logic at system level and the logics at subsystem and constituent levels.
The breakdown of clauses as used in this document gives a gradual understanding of the approach to be adopted to construct an execution logic. For instance:
—   Clause 5 presents the end-purpose of a programme execution logic as well as the associated basic concepts and the constituents of this logic;
—   Clause 6 describes and characterizes the process for building the logic;
—   Clause 7 concerns change control to the execution logic;
—   Clause 8 concentrates on the importance of capitalization and lessons learned.
This document applies to aeronautical, space and defence programmes. The principles can be extended to other areas of activity.
It applies to realization of a single product, of several samples or of a series. It applies to any customer/supplier level, while ensuring consistency between successive levels.
The principles described concern all programme actors, from initial expression of need through to closure of the programme.

This document specifies a methodology for describing and managing interactions and a format for digital communication between actors in any use case associated with the management of an asset during all life cycle stages.

—     an appropriate way to map responsibilities and interactions that provides a process context for information flow;
—     a format in which the interaction framework is specified and executed.
This document is intended to promote secure, verifiable, traceable and high-quality digital IDM communication between actors during all phases of the life cycle of assets, facilitate interoperability between software applications used, and to provide a basis for data- and process-driven information exchange and traceability of communication.

This document specifies the laboratory method for measuring the sound absorption performance of road traffic noise reducing devices in reverberant conditions. It covers the assessment of the intrinsic sound absorption performance of devices that can reasonably be assembled inside the testing facility described in EN ISO 354.
This method is not intended for the determination of the intrinsic characteristics of sound absorption of noise reducing devices to be installed on roads in non-reverberant conditions.
The test method in EN ISO 354 referred to in this document excludes devices that act as weakly damped resonators. Some devices will depart significantly from these requirements and in these cases, care is needed in interpreting the results.

This document specifies the general requirements for the measurement and evaluation of human exposure to hand-transmitted shock vibrations. For the purposes of this document, hand-transmitted shock vibration is any impactive or impulsive vibration that the machine or tool produces as a sequence of single events (isolated shock vibrations) linked by periods of no, or lower vibration.
This document specifies parameters for the evaluation of machinery emissions of hand-transmitted shocks in the frequency range covered by ISO 5349-1 (nominally the frequency range covered by the octave bands from 8 Hz to 1 000 Hz).
NOTE            It is recognised that shock vibration often includes substantial high-frequency vibration energy. Therefore, reporting of information on hand-transmitted shock at higher frequencies that those specified in this document can be valuable.

—   the determination of sound diffraction index difference of added devices in actual use;
—   the comparison of design specifications with actual performance data after the completion of the construction work;
—   the verification of the long-term performance of added devices (with a repeated application of the method);
—   the interactive design process of new products, including the formulation of installation manuals.
The test method can be applied both in situ and on samples purposely built to be tested using the method described here.
Results are expressed as a function of frequency, in one-third octave bands between 100 Hz and 5 kHz. If it is not possible to get valid measurements results over the whole frequency range indicated, the results are given in the restricted frequency range and the reasons of the restriction(s) are clearly reported. A single-number rating is calculated from frequency data.
For indoor measurements, see Annex D.

This document specifies a method for the determination of nitrate as NO3-N in water of various origin such as natural water (including groundwater, surface water and bathing water), drinking water and wastewater, in a measuring range of concentration between 0,20 mg/l and 30 mg/l of NO3-N using the small-scale sealed tube method. Different measuring ranges of small-scale sealed tube methods can be required.
The measuring ranges can vary depending on the type of the small-scale sealed tube method of different manufacturers.
It is up to the user to choose the small-scale sealed tube test with the appropriate application range or to adapt samples with concentrations exceeding the measuring range of a test by preliminary dilution.
NOTE 1   The results of a small-scale sealed tube test are most precise in the middle of the application range of the test.
Manufacturers' small-scale sealed tube methods are based on chromotropic colour reaction, depending on the typical operating procedure of the small-scale sealed tube used, see Clause 9.
NOTE 2      Laws, regulations or standards can require that the data is expressed as NO3 after conversion with the stoichiometric conversion factor 4,426 81 in Clause 11.
NOTE 3   In the habitual language, use of sewage treatment and on the displays of automated sealed-tube test devices, NO3 without indication of the negative charge has become the common notation for the parameter nitrate and especially for the parameter nitrate-N. This notation is adopted in this document even though not being quite correct chemical nomenclature.

This document considers liquid atmospheric precipitation (rain) and defines the procedures and equipment to perform laboratory tests, in steady-state conditions, for the calibration, check and metrological confirmation of non-catching rainfall measurement instruments. This document is not applicable to field performance.
It provides a classification of non-catching measurement instruments based on their laboratory performance. The classification does not relate to the physical principle used for the measurement, nor does it refer to the technical characteristics of the instrument assembly but is solely based on the instrument calibration.
Attribution of a given class to an instrument is not intended as a high/low ranking of its quality but rather as a quantitative standardized method to declare the achievable measurement accuracy to provide guidance on the suitability for a particular purpose, while meeting the user’s requirements.

NOTE 6   The PAS is regarded as a safety relevant system whereas the CFA system and communication device system are non-safety relevant aids to passengers.

The European Commission will in its project "VAT in the digital age" (ViDA) mandate that VAT reporting on intra-EU transactions is performed in near real-time and based on EN 16931-1. This Technical Report defines the impact of this legislation on the various deliverables of CEN/TC 434, with a focus on the subset to be sent to tax authorities and how EN 16931-1 needs to be changed. The ViDA package applies to all EU member states and specific territories where the VAT legislation applies (e.g. Northern Ireland in respect to goods).
This document does not define the content of the common electronic message based on the electronic invoice to be sent to the authorities. The definition of that common electronic message (DRR message) is a task of the European Commission, possibly with help of CEN. As the DRR message is not an invoice, but a VAT report, it is not to be regarded as a Core Invoice Usage Specification (CIUS). The DRR message therefore needs not to obey the rules for developing a CIUS. For example, not all mandatory elements in the invoice need to be part of the DRR message.
