Primary batteries - Part 4: Safety of lithium batteries (IEC 60086-4:2025)
EN IEC 60086-4:2025

IEC 60086-4:2025 specifies tests and requirements for primary lithium batteries to ensure their safe operation under intended use and reasonably foreseeable misuse.
This sixth edition cancels and replaces the fifth edition published in 2019. This edition includes the following significant technical changes with respect to the previous edition:
- Added definitions for leakage and venting, in addition to the test criteria;
- Revised overdischarge test;
- Revised marking requirements;
- Revised criteria for the child resistant packaging test;
- Changed the purpose of Annex F from "informative" to "normative";
- Added a new Annex G with additional measures against misuse of batteries not intended for consumer replacement;
- Integrated the contents of Interpretation Sheet 1 (IEC 60086-4:2019/ISH1:2020);
- In Clause 3, terms were reordered according their functions: basic terms, electrochemical systems, battery shapes, battery sizes, electrical characteristics, specifications, safety aspects, failure modes;
- In 6.4.4, the exemption for the shock acceleration for lithium primary batteries was reduced from 12 kg to 4,482 kg in order to reflect the fact that this is the threshold in IEC 62281, Test T-4, where the peak acceleration decreases below 150 gn.

Ultrasonics - Therapeutic focused short pressure pulse sources - Characteristics of fields (IEC 61846:2025)
EN IEC 61846:2025

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.

Washer-disinfectors - Part 1: General requirements, terms and definitions and tests (ISO 15883-1:2024)
EN ISO 15883-1:2025

This document specifies general performance requirements for washer-disinfectors (WD) and washer-disinfector accessories that are intended to be used for cleaning and disinfection of reusable medical devices. It specifies performance requirements for cleaning and disinfection as well as for the accessories that can be required to achieve the necessary performance. The methods and instrumentation required for validation, routine control and monitoring and requalification, periodically and after essential repairs, are also specified.
NOTE 1        The requirements can be applied to WD intended for use with other articles used in the context of medical, dental, pharmaceutical and veterinary practice.
The requirements for WD intended to process specific loads are specified in ISO 15883-2, ISO 15883-3, ISO 15883-4, ISO 15883-6 and ISO 15883-7. For WD intended to process loads of two or more different types, the requirements of the applicable parts of ISO 15883-2, ISO 15883-3, ISO 15883-4, ISO 15883-6 and ISO 15883-7 apply.
This document does not specify requirements intended for machines for use for laundry or general catering purposes.
This document does not include requirements for machines which are intended to sterilize the load, or which are designated as “sterilizers” and addressed in other standards.
The specified performance requirements of this document do not ensure the inactivation or removal of the causative agent(s) (prion protein) of transmissible spongiform encephalopathies.
NOTE 2        Chemicals in some cleaning agents and disinfectants can react with prion protein in a manner that can inhibit its removal or inactivation.  If the presence of prion protein is considered a possibility, then this can influence the choice of cleaning agent and disinfectant.
NOTE 3        This document can be used by prospective purchasers and manufacturers as the basis of agreement on the specification of a WD. The test methods for demonstration of conformity with the requirements of this document can also be employed by users to demonstrate continued conformity of the installed WD throughout its service life. Guidance on a routine test programme is given in Annex A.
