This document specifies a method for the measurement of focal spot sizes within the range of 5 µm to 300 µm of X-ray systems up to and including 225 kV tube voltage. This determination is based on the evaluation of an image with a dedicated focal spot that has been radiographically recorded using an edge and evaluated with a digital method.
The imaging quality and the resolution of X-ray images depend highly on the characteristics of the effective focal spot, in particular its size and the two-dimensional intensity distribution as seen from the detector plane.
For the characterization of commercial X-ray tube types (i.e. for advertising or trade), the nominal values of Annex A are preferred.
NOTE            The same procedure can be used at higher kilovoltages by agreement but the accuracy of the measurement can be poorer.

This document is applicable to environmental matters for a digital service. It establishes requirements and recommendations applicable for requirements gathering, design, implementation, operations, maintenance and the end of life of digital services in order to minimise adverse environmental impacts during all stages of its life cycle. It also establishes a common language and understanding on this subject. This document focuses on reducing the environmental impacts of a digital service. It therefore does not address all aspects of digital service design. For example, it does not address other aspects such as performance, resilience, reliability, availability or development language choice (see other standards covering these topics, e.g. ISO/IEC 25010 and ISO/IEC 27001). This document does not include matters linked to other corporate social responsibility (CSR) topics, e.g. social, cultural, diversity, inclusion or exclusion. This document is applicable to all development methodologies (waterfall, agile, etc.).

The objective of this document is to conduct a neutral salt spray test in accordance with ISO 9227. The test is a proven method for assessing the corrosion protection of coatings of components such as bolts. For this reason, two coating variants were chosen for conducting the tests on hexagon bolts with a size of M6 × 50. The bolts were examined at specified points in time and the time of occurrence of grey veil, white rust and red rust was documented. The corrosivity of the salt spray was determined by means of two methods and also documented in an evaluation form. These two methods are the assessment of the mass loss of an uncoated steel panel as specified in ISO 9227 as well as the determination of the time until appearance of red rust on hot-dip galvanized steel panels in accordance with ISO 4042 and ISO 10683. The processing steps are specified in detail in a manual that was provided to the test participants. If followed precisely, these instructions allow for a comparative analysis of the results from the individual labs and make it possible to determine the reproducibility of the salt spray test. Another objective is to compare the two methods used to determine the corrosivity of the salt spray in order to establish the suitability of these methods by comparing the corrosion assessment results obtained for the bolts. In addition, the normative operating parameters (temperature in the test cabinet, collection rate, pH and density or NaCl concentration of the solution collected) were documented for every inspection date in order to ascertain whether there is any correlation with the results of the corrosion assessment performed on the bolts.

This document provides a generic description of the methods available for measuring soil characteristics and indicators of core ecological soil functions. No distinction of context is made, i.e. no differentiation of land use and management (e.g agricultural, forest, urban, natural or contaminated lands). For each ecological soil function, the document specifically lists biotic and abiotic characteristics that can be measured. It focuses on characteristics and indicators that are either available as ISO documents or published in peer-reviewed papers. This document applies to ecological soil functions and is not applied to soil functions such as geotechnical functions (foundation support for buildings, tunnels, etc.) or geothermal functions. Indeed, ecosystem services do not address soils without a topsoil, or with a covered topsoil (buildings, infrastructure, greenhouse farming, solar panel parks). Methods and indicators for ecological soil functions can help in the assessment of soil-related ecosystem services but the overall assessment of ecosystem services is not covered in this document. Other methods based on proxy indicators (e.g. soil occupation, hydrography parameters) can also be used for land planning at large scale. These indicators are not included in this document.

The present document aims at further simplifying end-user access to ICT devices, services, and applications by providing recommended terms for basic and commonly-used ICT-related objects and activities, notably those terms that end users are commonly exposed to. Recommended terms are provided in 27 languages: Bulgarian, Croatian, Czech, Danish, Dutch, English, Estonian, Finnish, French, German, Greek, Hungarian, Icelandic , Irish, Italian, Latvian, Lithuanian, Maltese, Norwegian, Polish, Portuguese, Rhaeto Romance, Romanian, Slovak, Slovenian, Spanish, and Swedish (as spoken in their respective European countries).
The recommended terms apply to mobile ICT devices and mobile applications (whether they are standalone or provide access to related services) commonly found in mobile ICT devices. Though developed in a mobile ICT context, most of the recommended terms are applicable to both mobile and fixed-network devices, services, and applications. The recommended terms are applicable to the User Interface (UI) design for a product as well as that of any user documentation accompanying it.
User requirements and, when available, industry-originated documents as well as results of previous standardization work have been considered and integrated in the present document, providing implementation-oriented guidance. Wherever possible, a Design-for-All approach has been adopted, taking functional abilities of users, including elderly users and users with cognitive, physical, or sensory limitations into account.
The present document provides recommendations for terms that may be used by those who consider supporting the languages addressed in future products and services. It does not provide design guidance, nor does it intend to restrict the ability of market players to further improve and develop their devices and services. Neither does it intend to limit their options to trademark user interface elements or profile the user experience of brand-specific user interface implementations as a competitive edge.

This document specifies a mould (designated the type F ISO mould) for the injection moulding of plates with a preferred size of 80 mm × 120 mm, and a preferred thickness of 2 mm for single-point and multi-point data acquisition. Suitable test specimens according to ISO 20753 type A22 or B3 are then machined or stamped from the plates and used to obtain information on the anisotropy. For the design of plastic parts, this will provide upper and lower bounds for the tensile properties.
Investigation of the anisotropy of materials is a special procedure intended to provide guidance in the design of mouldings for end-use applications and is not intended as a quality control tool.
In the injection moulding of thermoplastic materials, the flow of molten polymer can influence the orientation of fillers such as fibreglass or the orientation of polymer chains, resulting in anisotropic behaviour.
For the purposes of this document, the flow direction is defined as the direction from the gate to the far end of the mould cavity and the cross direction as the direction perpendicular to the flow direction.
The type F mould is not intended to replace the type D mould used to determine the moulding shrinkage of thermoplastics.

This document specifies a method for measuring the Palmqvist toughness of hardmetals and cermets at room temperature by an indentation method. This document is applicable to a measurement of toughness, called Palmqvist toughness, calculated from the total length of cracks emanating from the corners of a Vickers hardness indentation, and it is intended for use with metal-bonded carbides and carbonitrides (normally called hardmetals, cermets or cemented carbides). The test procedures specified in this document are applicable for use at ambient temperatures, but can be extended to higher or lower temperatures by agreement. The test procedures specified in this document are also applicable for use in a normal laboratory-air environment. This document is not applicable for use in corrosive environments, such as strong acids or seawater.

This document specifies a method of measuring smoke production from the exposed surface of specimens of materials or composites. It is applicable to specimens that have an essentially flat surface and do not exceed 25 mm in thickness when placed in a horizontal orientation and subjected to specified levels of thermal irradiance in a closed cabinet with or without the application of a pilot flame. This method of test is applicable to all plastics.
It is intended that the values of optical density determined by this test be taken as specific to the specimen or assembly material in the form and thickness tested and are not to be considered inherent, fundamental properties.
The test is intended primarily for use in research and development and fire safety engineering in buildings, trains, ships, etc. and not as a basis for ratings for building codes or other purposes. No basis is provided for predicting the density of smoke that can be generated by the materials upon exposure to heat and flame under other (actual) exposure conditions. This test procedure excludes the effect of irritants on the eye.
NOTE            This test procedure addresses the loss of visibility due to smoke density, which generally is not related to irritancy potency (see Annex E).
It is emphasized that smoke production from a material varies according to the irradiance level to which the specimen is exposed. The results yielded from the method specified in this document are based on exposure to the specific irradiance levels of 25 kW/m2 and 50 kW/m2.

IEC 60335-2-105:2026 deals with the safety of electric multifunctional shower cabinets and electric separate multifunctional shower units for household and similar purposes, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances including DC supplied appliances. Appliances not intended for normal household use but which nevertheless can be a source of danger to the public, such as appliances intended to be used by laymen in hotels, fitness centres and similar locations, are within the scope of this standard.
As far as is practicable, this standard deals with the common hazards presented by appliances that are encountered by all persons in and around the home. However, in general, it does not take into account
- persons (including children) whose physical, sensory or mental capabilities; or lack of experience and knowledge prevents them from using the appliance safely without supervision or instruction;
- children playing with the appliance.
Attention is drawn to the fact that
- for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements can be necessary;
- in many countries, additional requirements are specified by the national health authorities, the national water supply authorities, the national authorities responsible for the protection of labour and similar authorities;
- in many countries, mechanical strength, impact resistance and shattering properties of shower enclosures can be covered by national regulations.
If an appliance incorporates a part that is within the scope of IEC 60598 series or IEC 62368 series, the part is tested in accordance with the relevant standard as far as reasonable.
This standard does not apply to
- instantaneous water heaters used for showering (IEC 60335-2-35);
- shower-boost pumps (IEC 60335-2-41);
- appliances intended for medical purposes;
- appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas).

This document provides guidance on characterizing the modifications of river hydromorphological features described in EN 14614:2020. Both standards focus more on morphology than on hydrology and continuity, and include a consideration of sediment and vegetation. This document will enable consistent comparisons of hydromorphological forms and processes between rivers within a country and between different countries in Europe, providing guidance for broad-based characterization across a wide spectrum of hydromorphological modification of river channels, banks, riparian zones and floodplains. Although of lesser focus, it considers the indirect effects of catchment-wide modifications to these river and floodplain environments. Its primary aim is to assess ‘departure from naturalness’ as a result of historical and modern human pressures on river hydromorphology, and it suggests suitable sources of information (see EN 14614:2020, Table A.1) which may contribute to characterizing the modification of hydromorphological properties. In doing so, it does not replace methods that have been developed for local assessment and reporting.
Decisions on river management for individual reaches or catchments require expert local knowledge and vary according to river type.

b) Option B - repeated test, with the same test parameters as the basic method with additional information
in Option A, see Annex B.
c) Option C - modified method for testing hydrophobic nonwovens specifying another degree of incline, see Annex C.
The test method is designed to measure the repellency of hydrophobic nonwovens. At the standard inclination angle, Option A isn’t able to distinguish between different levels of hydrophobicity. By decreasing the inclination of the table, one can assess the difference in repellence of hydrophobic nonwovens.
For R&D purposes, other characteristics can be measured according to Annex D.

IEC 62083:2025 cancels and replaces the second edition published in 2009. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
– modification of the title from Medical electrical system - Requirements for the safety of radiotherapy treatment planning systems, to Medical device software - Requirements for the safety of radiotherapy treatment planning systems;
– Adaptive radiotherapy is added with Clause 16;
– The title reflects different implementations of radiotherapy treatment planning systems.

1.1   General
This document establishes the minimum requirements for the qualification and certification of personnel performing nondestructive testing (NDT), nondestructive inspection (NDI), or nondestructive evaluation (NDE) in the aerospace manufacturing, service, maintenance and overhaul industries. For the purposes of this document, the term NDT will be used and will be considered equivalent to NDI and NDE.
In Europe, the term "approval" is used to denote a written statement by an employer that an individual has met specific requirements and has operating approval. The term "certification" as defined in 3.3 is used throughout this document as a substitute for the term "approval". Except when otherwise specified in the written practice, certification in accordance with this document includes operating approval.
1.2   Purpose
1.2.1   Applicability
This document applies to personnel who:
-   use NDT methods or equipment to test and/or accept materials, products, components, assemblies or sub-assemblies;
-   are directly responsible for the technical adequacy of the NDT methods and equipment used;
-   operate automatic interpretation or evaluation systems;
-   approve NDT procedures or work instructions;
-   audit NDT facilities; or
-   provide technical NDT support or training.
This document does not apply to individuals who only have administrative or supervisory authority over NDT personnel or to research personnel developing NDT technology for subsequent implementation and approval by a certified Level 3. See Clause 8 regarding applicability to personnel performing specialized inspections using certain direct readout instruments.
1.2.2   Implementation
This document addresses the use of a National Aerospace NDT Board (NANDTB). NANDTBs are only used as specified per Annex C and it is not mandatory to have such a board for compliance with this document. Personnel certified to previous revisions of NAS410/EN 4179 need not recertify to the requirements of this document until their current certification expires.
1.2.3   NDT methods
This document contains detailed requirements for the following NDT methods:
eddy current testing   (ET)
penetrant testing   (PT)
magnetic particle testing   (MT)
radiographic testing   (RT)
shearography testing   (ST)
thermographic testing   (IRT)
ultrasonic testing   (UT)
When invoked by engineering, quality, cognizant engineering organization or prime contractor requirements, this document applies to other NDT methods used to determine the acceptability or suitability for intended service of a material, part, component, sub-assembly or assembly. Such methods can include, but are not limited to, acoustic emission, neutron radiography, leak testing, and holography.

This document specifies a method for the determination of the transverse rupture strength of sintered metal materials, excluding hardmetals. The method is particularly suitable for comparing the sintered strength of a batch of metal powder with that of a reference powder or with a reference strength.
The method is applicable to sintered metal materials, excluding hardmetals, whether they have been subjected to heat treatment after sintering or not, and also to materials that have been sized or coined after sintering.
It is especially suitable for materials having a uniform hardness throughout their section and negligible ductility, i.e. a ductility corresponding to a permanent deformation of less than about 0,5 mm measured between the two supports during the transverse rupture strength determination.
NOTE            The permanent deformation can be measured with sufficient precision from the two fragments of the broken or cracked bar by indexing the lower surface. Alternatively, the deflection of a straight line drawn horizontally on the side of the test piece can be measured using an optical instrument such as a measuring microscope or optical comparator.
