This document specifies the requirements for testing items of equipment intended for use on railway vehicles which are subsequently subjected to vibrations and shock owing to the nature of railway operational environment. To gain assurance that the quality of the equipment is acceptable, it is exposed to tests of reasonable duration that simulate the service conditions seen throughout its expected life.
Simulated long-life testing can be achieved in a number of ways each having their associated advantages and disadvantages, the following being the most common:
a) amplification: where the amplitudes are increased and the time base decreased;
b) time compression: where the amplitude history is retained and the time base is decreased (increase of the frequency);
c) decimation: where time slices of the historical data are removed when the amplitudes are below a specified threshold value.
The amplification method as stated in item a) above, is used in this document and together with the publications referred to in Clause 2; it defines the default test procedure to be followed when vibration testing items for use on railway vehicles.
Whilst this document is primarily concerned with railway vehicles on fixed rail systems, its wider use is not precluded. For systems operating on pneumatic tyres, or other transportation systems such as trolleybuses, where the level of shock and vibration clearly differ from those obtained on fixed rail systems, specific test levels can be considered. In that case, the frequency spectra and the shock duration and amplitude are computed in compliance with the guidelines in Annex A.
Annex F provides the functional random vibration load that can be considered by the user for urban vehicles operating on pneumatic tyres.
This document applies to single axis testing. However, multi-axis testing is possible.
The anchoring bolts at the fixing point(s) of the equipment are not evaluated in this document.
This document is intended to evaluate equipment which is attached to the main structure of the vehicle (and components mounted thereon). It is not intended to test equipment which forms part of the main structure. Main structure in the sense of this document means car body, bogie and axle.
The following items are out of scope of this document:
– the traction motors for railway vehicles;
– any mechanical substructure not equipped with electrical, electronic or pneumatic component.
Additional or special vibration tests for some specific equipment are not specified in this document, for example:
a) equipment mounted on, or linked to, items which are known to produce defined frequency excitation;
b) equipment such as pantographs, shoegear, or suspension components which are known to be exposed to specific shock and vibration excitation;
c) equipment intended for use in special operational environments as specified by the customer;
d) transportation and handling tests.

This document applies to hearing aid fitting management (HAFM) services offered by hearing aid professionals (HAP) when providing benefit for their clients. The provision of hearing aids relies on the knowledge and practices of a hearing aid professional, to ensure the proper fitting and adequate service in the interest of the client with hearing loss. This document specifies general processes of HAFM from the client profile to the follow-up through administering, organising and controlling hearing aid fitting through all stages. It also specifies important preconditions such as education, facilities and systems that are required to ensure proper services. The focus of this document is the services offered to the majority of adult clients with hearing impairment. It is recognized that certain populations with hearing loss such as children, persons with other disabilities or persons with implantable devices can require services outside the scope of this document. This document generally applies to air conduction hearing aids and for the most part also to bone conduction devices. Hearing loss can be a consequence of serious medical conditions. Hearing aid professionals are not in a position to diagnose or treat such conditions. When assisting clients seeking hearing rehabilitation without prior medical examination, hearing aid professionals are expected to be observant of symptoms of such conditions and refer to proper medical care. Further to the main body of the document, which specifies the HAFM requirements and processes, several informative annexes are provided. Appropriate education of hearing aid professionals is vital for exercising HAFM. Annex A defines the competencies required for the HAFM processes. Annex B offers a recommended curriculum for the education of hearing aid professionals. Annex C is an example of an appropriate fitting room. Annex D gives guidance on the referral of clients for medical or other specialist examination and treatment. Annex E is a recommendation for important information to be exchanged with the client during the process of HAFM. Annex F is a comprehensive terminology list offering definitions of the most current terms related to HAFM. It is the intention that these annexes be helpful to those who wish to deliver HAFM of the highest quality.

This document applies to the testing of surfaces that may become contaminated by radioactive materials.
The ease of decontamination is a property of a surface and an important criterion for selecting surface
materials used in the nuclear industry, interim storage or disposal facilities from which contamination can
be removed easily and rapidly without damaging the surface. The test described in this document is a rapid
laboratory-based method to compare the ease of decontamination of different surface materials.
The results from the test can be one parameter to take into account when selecting surface coatings such
as varnish or impervious layers such as ceramics and other surfaces. The radionuclides used in this test
are those commonly found in the nuclear industry (137Cs, 134Cs and 60Co) in aqueous form. The test can also be adopted for use with other radionuclides and other chemical forms, depending on the customer requirements, if the solutions are chemically stable and do not corrode the test specimen.
The test does not measure the ease of decontamination of the surface materials in practical use, as this
depends on the radionuclide(s) present, their chemical form, the duration of exposure to the contaminant
and the environmental conditions amongst other factors.
The test method is not intended to describe general decontamination procedures or to assess the efficiency of decontamination procedures (see ISO 7503-1 to ISO 7503-3).
The test method is not suitable for use of radiochemicals if the radionuclide emits low energy gamma rays or beta particles that are readily attenuated in the surface.

IEC TR 62669:2026 presents a series of case studies in which electromagnetic field (EMF) exposure is evaluated in accordance with IEC 62232:2025 [1]. The case studies presented in this document involve intentionally radiating base stations (BSs). The BS transmits on one or more antennas using one or more frequencies in the range 110 MHz to 300 GHz. RF exposure assessments consider, as a minimum, the contribution of ambient sources in at least the 100 kHz to 300 GHz frequency range.
Case studies presented in this document illustrate typical usage of IEC 62232:2025 for the RF exposure assessments of the most common BS types, deployed in mobile and wireless networks, such as small cells, street cells, macro BSs, and parabolic dish antennas used for wireless transmission or mobile backhaul. Many case studies also illustrate the implementation of the actual maximum approach and RF exposure assessment of massive multiple-input, multiple-output (mMIMO) BSs, which are deployed in operational mobile networks, such as 5G.
The case studies are provided for guidance only and are not a substitute for a thorough understanding of the requirements of IEC 62232:2025. Based on the technical outcome and lessons learned from each case study, suggestions are made about RF assessment topics to be considered in the next edition of IEC 62232. New assessment techniques for metrics specified in ICNIRP-2020 [2], such as whole-body average SAR (wbSAR) above 10 GHz and absorbed power density (APD), are also introduced.
NOTE 1 Trade names and trademarks of measurement equipment and computation tools given in this document and in the attached test reports are examples of suitable products available commercially. This information is given for the convenience of users of this document and does not constitute an endorsement by IEC of these products.
NOTE 2 The lower frequency considered for ambient sources, 100 kHz, is derived from ICNIRP-2020 [2] and ICNIRP-1998 [3]. Some applicable exposure limit guidelines, however, require ambient fields to be evaluated as low as 3 kHz, e.g. IEEE Std C95.1-2019 [4] and Safety Code 6 [5].
This third edition cancels and replaces the second edition published in 2019. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) additional case studies and technical updates illustrating the implementation of IEC 62232:2025;
b) general implementation of the actual maximum approach for beamforming antennas;
c) validation of power or EIRP control features;
d) in-situ measurement and implementation of extrapolation methods;
e) introduction of emerging laboratory measurement methods for product compliance assessments.

1.1 General
This document specifies methods for determining the sound power level of a noise source from sound pressure levels measured on a surface enveloping the noise source (machinery or equipment) in an environment that approximates to an acoustic free field near one or more reflecting planes. The sound power level produced by the noise source, in frequency bands or with A-weighting applied, is calculated using those measurements.
NOTE Differently shaped measurement surfaces can yield differing estimates of the sound power level of a given noise source which are accounted for in the uncertainty associated with this test method. An appropriately drafted noise test code (see ISO 12001) gives detailed information on the selection of the surface.
1.2 Types of noise and noise sources
The methods specified in this document are suitable for all types of noise (steady, non-steady, and fluctuating) as defined in ISO 12001, except for short duration, impulsive events.
This document is applicable to all types and sizes of noise source (e.g. stationary or slowly moving component or sub-assembly), provided that the conditions for the measurements can be met.
NOTE It is possible that the conditions for measurements given in this document are impracticable for very tall or very long sources such as chimneys, ducts, conveyors and multi-source industrial plants. A noise test code for the determination of noise emission of specific sources can provide alternative methods in such cases.
1.3 Test environment
The test environments that are applicable for measurements made in accordance with this document can be located indoors or outdoors, with one or more sound-reflecting planes present on or near which the noise source under test is mounted. The ideal environment is a completely open space with no bounding or reflecting surfaces other than the reflecting plane(s), such as that provided by a qualified hemi-anechoic chamber, but procedures are given for applying corrections (within limits that are specified) in the case of environments that are less than ideal. Annex A or ISO 26101-2 specifies methods for determining the adequacy of the test environment and for determination of corrections to be applied to account for the effect of the test environment.
1.4 Measurement uncertainty
Information is given on the uncertainty of the sound power levels determined in accordance with this document, for measurements made in limited bands of frequency and with frequency A-weighting applied. Annex I specifies procedures for testing laboratories that can be used to reduce measurement uncertainty. The uncertainty conforms to ISO 12001, accuracy grade 2 (engineering grade). General information on measurement uncertainty is provided in this document and additional information can be found in ISO 5114-1[8].

IEC 62828-1:2026 establishes a general framework for defining reference conditions and test procedures applicable for assessing the measurement performances of all types of industrial and process measurement transmitters (PMTs) used in measuring and control systems for industrial process and machinery. For the purpose of this document, an analogue PMT is a process measurement transmitter with only analogue current and/or voltage output(s), irrespective the technology adopted and the complexity of the circuitry. All the other process measurement transmitters, with digital output(s) only or with hybrid analogue and digital output(s), are considered to be digital PMTs. This document constitutes a common reference for the other parts of the IEC 62828 series. Specific test procedures and additional requirements for given types of PMTs (pressure, temperature, level, flow, etc.) are covered by other parts of this series. Sensing devices according to the IEC 60947 series are excluded from the scope of this document.
NOTE 1 In industrial and process applications, to indicate the process measurement transmitters, it is common also to use the terms "industrial transmitters", or "process transmitters".
NOTE 2 For better clarity, when the complete definition "industrial and process measurement transmitter" makes the sentence too long in this document, the short term "transmitter", or PMT, is used instead.
This second edition cancels and replaces the first edition published in 2017. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) informative Annexes E, F, G and H have been removed;
b) a new informative Annex G “Example of signal current for a 4 mA to 20 mA PMT” has been introduced (it has been moved from IEC 62828-2:2017 to this document);
