Issue Num.:  25627
Commitee: CEI-CT29/87
La presente Norma si applica alle apparecchiature terapeutiche che generano onde di pressione focalizzate extracorporee e a quelle che generano energia meccanica focalizzata non termica, escludendo dispositivi per litotrissia percutanea/laser, impulsi ultrasonori a lunga durata (come l’istotripsia) e sistemi non focalizzati. Definisce i parametri misurabili per dichiarare l’output acustico di tali dispositivi e specifica metodi per caratterizzare il campo di pressione generato. Rispetto alla prima edizione del 1998, intitolata "Pressure pulse lithotripters" e focalizzata esclusivamente sulla litotrissia renale, la revisione del 2025 amplia l’ambito a terapie per patologie ortopediche, cardiache, cerebrali e altre condizioni, modificando il titolo in "Therapeutic focused short pressure pulse sources" per riflettere questa estensione. Tra le principali innovazioni tecniche figurano l’introduzione di parametri basati su "−n dB" e "n MPa" per una maggiore precisione, l’aggiunta di indicatori come l’indice di induzione della cavitazione e la dose energetica totale degli impulsi, e la ridefinizione della classificazione degli idrofoni, distinguendo tra quelli per misurazioni di pressione e quelli per controllo qualità. La norma si allinea agli standard recenti, come ad esempio la Norma CEI EN IEC 62127-1:2022, e incorpora i risultati dalla letteratura scientifica più aggiornata. La presente Norma sostituisce totalmente la CEI EN 61846:1999 - Fascicolo 5424 che rimane applicabile fino al 31/03/2028. La presente Norma recepisce il testo originale inglese della Pubblicazione IEC. Questa pubblicazione è il recepimento in lingua inglese della Norma europea EN IEC 61846:2025 come Norma nazionale italiana.

ICS

International Classification for Standards (ICS) is an international classification system for technical standards.

The ICS is a hierarchical classification organized on three levels.

Level 1 covers the main fields of activity in standardization, e.g. road vehicle engineering, agriculture, metallurgy.

Each field has a two-digit notation, e.g.

  43    Road Vehicle Engineering

The main fields are subdivided into groups (level 2). The notation of a group consists of the field notation and a three-digit group number, separated by a point, e.g.

  43.040    Road vehicle systems

Some groups are further divided into sub-groups (level 3). The notation of a sub-group consists of the group notation and a two-digit number, separated by a point, e.g.

  43.040.20 Lighting, signaling and warning devices

You can identify the ICS code of your interest by typing the code or a keywordword in the dropdown ICS field, and by selecting one of the filtered results.

Search also in the summary/description of the standard

By flagging this control, the search for keywords will not be limited to the Standard Number and Title fields, but will also be performed in the Abstract of the standard.

This way, you will get more results.

You should use this option when you can not find the desired result with the standard approach and it is necessary to extend the scope of the search: by increasing the number of results, you will increase the number of non-relevant elements, as well.
