IEC 62282-8-201:2024 is available as IEC 62282-8-201:2024 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 62282-8-201:2024 defines the evaluation methods of typical performances for electric energy storage systems using hydrogen. It is applicable to the systems that use electrochemical reaction devices for both power charge and discharge. This document applies to systems that are designed and used for service and operation in stationary locations (indoor and outdoor). It specifies performance evaluation methods for electric energy storage systems using hydrogen that employ electrochemical reactions both for water and steam electrolysis and electric power generation. This document is intended for power-to-power systems which typically employ a set of electrolyser and fuel cell, or a reversible cell for devices of electric charge and discharge. This second edition cancels and replaces the first edition published in 2020.
This edition includes the following significant technical changes with respect to the previous edition:
a) consideration of systems connected to hydrogen supply infrastructure (hydrogen grids, vessels, caverns or pipelines);
b) hydrogen input and output rate is added in the system parameters (5.10);
c) electric energy storage capacity test is revised (6.2);
d) roundtrip electrical efficiency test is revised (6.5);

IEC 61674:2024 specifies the performance and some related constructional requirements of DIAGNOSTIC DOSIMETERS intended for the measurement of AIR KERMA, AIR KERMA LENGTH PRODUCT or AIR KERMA RATE, in photon radiation fields used in medical X-ray imaging, such as RADIOGRAPHY, RADIOSCOPY and COMPUTED TOMOGRAPHY (CT), for X-RADIATION with generating potentials in the range of 20 kV to 150 kV. This document is applicable to the performance of DOSIMETERS with VENTED IONIZATION CHAMBERS and/or SEMICONDUCTOR DETECTORS as used in X-ray diagnostic imaging.
IEC 61674:2024 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:
a) for mammography, the manufacturer specifies the REFERENCE VALUE for the RADIATION QUALITY;
b) for mammography, the manufacturer provides the MINIMUM RATED RANGE of RADIATION QUALITIES for the compliance test on energy dependence of response;
c) the compliance test for analogue displays was removed;
d) the compliance tests for range reset, the effect of leakage and recombination losses were removed. These tests are already covered by the test on linearity and cannot be conducted for modern devices. The estimation of COMBINED STANDARD UNCERTAINTY was changed accordingly;
e) the compliance test for mains rechargeable and battery-operated dosimeters were updated for modern devices

CISPR 15:2024 Amendment 1
- Standard71 pagesEnglish and French languagesale 15% off
CISPR 15:2018 applies to the emission (radiated and conducted) of radiofrequency disturbances from:
- lighting equipment (3.3.16);
- the lighting part of multi-function equipment where this lighting part is a primary function;
- UV and IR radiation equipment for residential and non-industrial applications;
- advertising signs;
- decorative lighting;
- emergency signs.
Excluded from the scope of this document are:
- components or modules intended to be built into lighting equipment and which are not user-replaceable;
- lighting equipment operating in the ISM frequency bands (as defined in Resolution 63 (1979) of the ITU Radio Regulation);
- lighting equipment for aircraft and airfield facilities (runways, service facilities, platforms);
- video signs;
- installations;
- equipment for which the electromagnetic compatibility requirements in the radio-frequency range are explicitly formulated in other CISPR standards, even if they incorporate a built-in lighting function.
The frequency range covered is 9 kHz to 400 GHz. No measurements need to be performed at frequencies where no limits are specified in this document.
Multi-function equipment which is subjected simultaneously to different clauses of this document and/or other standards need to meet the provisions of each clause/standard with the relevant functions in operation.
For equipment outside the scope of this document and which includes lighting as a secondary function, there is no need to separately assess the lighting function against this document, provided that the lighting function was operative during the assessment in accordance with the applicable standard. The radiated emission requirements in this document are not intended to be applicable to the intentional transmissions from a radio transmitter as defined by the ITU, nor to any spurious emissions related to these intentional transmissions.
Within the remainder of this document, wherever the term "lighting equipment" or "EUT" is used, it is meant to be the electrical lighting and similar equipment falling in the scope of this document as specified in this clause. This ninth edition cancels and replaces the eighth edition published in 2013 and its Amendment 1:2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) full editorial revision and restructuring;
b) the restriction to mains and battery operation is deleted in the scope;
c) radiated disturbance limits in the frequency range 300 MHz to 1 GHz have been introduced;
d) the load terminals limits and the CDNE (alternative to radiated emissions) limits have changed;
e) deletion of the insertion-loss requirements and the associated Annex A;
f) introduction of three basic ports: wired network ports, local wired ports and the enclosure port;
g) introduction of a more technology-independent approach;
h) replacement of Annex B (CDNE) by appropriate references to CISPR 16-series of standards;
i) modified requirements for the metal holes of the conical housing;
j) new conducted disturbance measurement method for GU10 self-ballasted lamp;
k) addition of current probe measurement method and limits for various types of ports (in addition to voltage limits and measurement methods);
l) introduction of the term ‘module’ (instead of independent auxiliary) and requirements for measurement of modules using a host (reference) system;
m) modified specifications for stabilization times of EUTs;
n) for large EUT (> 1,6 m), addition of the magnetic field measurement method using a 60 cm loop antenna at 3 m distance (method from CISPR 14-1) as an alternative to the 3 m and 4 m LAS.
Keywords: emission (radiated and conducted) of radiofrequency disturbance

- Planning an experimental programme, including a design statement, technical drawings, facility selection, site data and other inputs as specified in Clause 5.
- Device characterisation, including the physical device model, PTO components and mooring arrangements where appropriate.
- Environment characterisation, concerning either the tank testing facility or the sea deployment site, depending on the stage of development.
- Specification of specific test goals, including power conversion performance, device motions, device loads and device survival.
This document prescribes the minimum test programmes that form the basis of a structured technology development schedule. For each testing campaign, the prerequisites, goals and minimum test plans are specified. This document serves a wide audience of wave energy stakeholders, including device developers and their technical advisors; government agencies and funding councils; test centres and certification bodies; private investors; and environmental regulators and NGOs.
