IEC 62554:2011 specifies sample preparation methods for determining mercury levels in new tubular fluorescent lamps (including single capped, double capped, self-ballasted and CCFL for backlighting) containing 0,1 mg mercury or more. The intended resolution of the methods described in this standard is of the order of 5 %. Mercury level measurement of spent lamps is excluded, as during lamp operation, mercury gradually diffuses into the glass wall and reacts with the glass materials. The test method of this standard does not recover mercury that is diffused into or reacted with or otherwise incorporated irreversibly with the glass wall of discharge tubes. This standard does not contain information on measurement. Measurement is specified in IEC 62321.

IEC 63563-11:2025 describes Magnetic power profile (MPP) which is a protocol extension that provides additional messages, new power states/modes, new power transfer contract elements, and aims to provide the following functionalities:
• Operating Frequency Negotiation
• Cloaking (Power Pause)
• Generic Information Exchange
• Simultaneous Data Stream Transactions
• Fast PTx to PRx communication
• Maximum Power and Power Control Profiles Determination
• Extended Power Negotiation
• Extended PTx/PRx Identification and Capabilities
• Extended Control Error Packets and Received Power Packets
• Power Transmitter Battery Level Reporting
• Ecosystem Scalability

It covers aspects of communication and relationships between the EXTERNAL BEAM EQUIPMENT and X-ray imaging devices, attached or not directly attached to, but in the same RADIATION shielded area as, and dedicated for use only with, the EXTERNAL BEAM EQUIPMENT. This document deals with equipment for OFFLINE X-IGRT, ONLINE X-IGRT and REAL-TIME X-IGRT. It covers procedures to reduce the risk of over-reliance on the X-IGRT EBE SYSTEM. For example, in the case of ONLINE X-IGRT, the MANUFACTURER will provide an interactive interface for user interaction with the correction suggested by the system. This document does not apply to CT SCANNERS, X-RAY EQUIPMENT for RADIOGRAPHY, and X-RAY EQUIPMENT for RADIOSCOPY, which are not intended for use for IGRT. Requirements that are being tested according to another standard can be identified by the manufacturer and if equivalent do not require retesting, instead evidence can refer to the CT SCANNER, X-RAY EQUIPMENT for RADIOGRAPHY, or X-RAY EQUIPMENT for RADIOSCOPY EQUIPMENT manufacturer's providing compliance statements or test reports. If the X-IGRT EQUIPMENT is combined with an MEE, any requirement that is the same for the X-IGRT EQUIPMENT and the MEE, such as a PATIENT POSITIONER, is not required to be tested twice, but can be accepted as tested by the MEE. This document applies for X-ray equipment for radiography, radioscopy, and COMPUTER tomography used for IGRT. If a clause or subclause is specifically intended to be applicable to X-IGRT EBE SYSTEMS, the content of that clause or subclause will say so. Where that is not the case, the clause or subclause applies only to X-IGRT EQUIPMENT.
This document, with the inclusion of TYPE TESTS and SITE TESTS, applies respectively to the MANUFACTURER and some installation aspects of X-IGRT EBE SYSTEMS intended to be:
• for NORMAL USE, operated under the authority of the RESPONSIBLE ORGANIZATION by QUALIFIED PERSONS having the required skills for a particular medical application, for particular specified clinical purposes, e.g., STATIONARY RADIOTHERAPY or MOVING BEAM RADIOTHERAPY,
• maintained in accordance with the recommendations given in the INSTRUCTIONS FOR USE, and

IEC 60335-2-119:2021 deals with the safety of commercial electric packaging appliances using vacuum conditions for food preservation, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances.
These appliances are not intended for household and similar purposes. They are used for commercial preservation of food in areas not open to the public, for example in kitchens of restaurants, canteens, hospitals and in commercial enterprises such as bakeries and butcheries.
Examples of appliances that are within the scope of this standard are:
– chamber vacuum packaging appliances;
– vacuum packaging appliances.
These appliances may be provided with a film-sealing function.
This standard also deals with the hygiene aspects of appliances.
As far as is practicable, this standard deals with the common hazards presented by appliances that are encountered by users. However, in general, it does not consider young children playing with the appliance.
Attention is drawn to the fact that:
– for appliances intended to be used in vehicles or onboard ships or aircraft, additional requirements may be necessary;
– in many countries, additional requirements for appliances incorporating pressure vessels are specified;
– in many countries, additional requirements are specified by the national health authorities, the national authorities responsible for the protection of labour, the national water supply authorities and similar authorities.

IEC SRD 63460:2025 The scope of this document is the assessment of how Electric Vehicles (EVs) may (or must) act as Distributed Energy Resources (DER) when they are interconnected to the electric power system through a charging station. Although clearly the main purpose for EV interconnection to the grid is to charge their batteries, EVs are capable of providing grid support functions while interconnected, and in some situations, may be mandated or incentivized to do so. This document provides Use Cases as examples of how EVs might provide such DER functionality, based on the grid support functions defined in IEC 61850-7-420, IEEE 1547:2018, and EN 50549.

IEC 61846:2025 is applicable to:
– therapy equipment using extracorporeally induced focused pressure pulse waves;
– therapy equipment producing focused mechanical energy excluding thermal energy.
This document does not apply to percutaneous and laser lithotripsy equipment.
This document does not apply to:
– histotripsy or other therapeutic ultrasound bursts of longer time duration than that of the pressure pulse;
– non-focused pressure pulse equipment.
This document specifies:
– measurable parameters which could be used in the declaration of the acoustic output of extracorporeal focused pressure pulse equipment;
– methods of measurement and characterization of the pressure field generated by focused pressure pulse equipment.
While this document has been developed for equipment intended for use in lithotripsy, it has been developed such that, as long as no other specific standards are available to be used for other medical applications of therapeutic extracorporeal focused pressure pulse equipment, this document can be used as a guideline.
IEC 61846:2025 cancels and replaces the first edition published in 1998. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) Change of title: "pressure pulse lithotripters" in the previous edition is changed to "therapeutic focused short pressure pulse sources" in order to take into account the development in the relevant technical and biomedical applications of such sources, which were originally used only for (kidney) lithotripsy, while recent applications include a wide range for the treatment of, for example, stone diseases, orthopaedic pain, tissue, cardiac and brain diseases.
The term "focused" was added to differentiate IEC 61846 from IEC 63045.
The term "short" was added to align the nomenclature to IEC 63045 and to differentiate IEC 61846 from standards in the HIFU and HITU fields.
b) Clause 1 and elsewhere in the document: The term "lithotripsy" is changed to "therapy" in order to account for the wide range of applications beyond stone diseases.
c) Clause 3: The "−6 dB" parameter definitions are replaced by "−n dB" to avoid misconceptions in the significance and use of these parameters and to account for newer findings in literature.
Additional "n MPa" parameters are introduced for the same reasons.
The definitions of "derived" parameters are aligned to those in recently published standards, for example IEC 62127-1.
New definitions were added which describe parameters appearing in newer relevant literature, for example "momentum", "average positive acoustic pressure", "cavitation induction index", "pulse to pulse variability", "total pressure pulse energy dose".
d) Clause 6: The terms "focus hydrophone" and "field hydrophone" were removed to account for newer technical developments. New terms distinguish between "hydrophones for pressure pulse measurements" and "hydrophones for quality assurance".
e) Annexes: Descriptions, tables and figures were edited to account for newer literature and standards as well as technical developments.

IEC 63453: 2025 specifies functional requirements for the validation of simulation techniques and tools used to assess the dynamic interaction between overhead contact lines and pantographs, as part of the prediction of current collection quality, to ensure confidence in, and mutual acceptance of the results of the simulations.
This document deals with:
- input and output parameters of the simulation;
- comparison with line test measurements, and the characteristics of those line tests;
- validation of pantograph models;
- comparison between different simulation tools;
- limits of application of validated methods to assessments of pantographs and overhead contact lines.
This document applies to the current collection from an overhead contact line by pantographs mounted on railway vehicles. It does not apply to trolley bus systems.
