La presente Norma definisce le prestazioni richieste per un apparecchio di misura della dose assorbita e del rateo di dose assorbita in aria, in situazioni d’emergenza. Nel caso di misure di radiazioni beta, deve essere utilizzata la dose assorbita in tessuto ad una profondità di 7 mg/cm2. Non specifica quali strumenti sono necessari e non prende in considerazione né il numero né la posizione precisa di questi strumenti. Se le norme nazionali richiedono l’utilizzo di grandezze radiometriche diverse (per es. l’equivalente di dose ambiente o direzionale), la presente Norma definisce le prestazioni richieste per l’apparecchiatura che misura queste diverse grandezze. Si applica soltanto ai complessi di misura portatili (qui indicati come strumenti). Il suo scopo è di stabilire le prestazioni fondamentali e i requisiti di progetto per gli strumenti di misura di dose e rateo di dose da campi elevati di radiazioni gamma e beta, utilizzati per un’immediata valutazione d’emergenza radiologica. In particolare specifica le caratteristiche generali, di funzionamento, elettriche, meccaniche, di sicurezza, ambientali, le modalità di prova e la documentazione richiesta.
La presente Norma costituisce la ristampa senza modifiche, secondo il nuovo progetto di veste editoriale, della Norma pari numero ed edizione (Fascicolo 2535).
La presente Norma é annullata e sostituita dalla Nuova Norma, CEI EN IEC 60846-2:2019-04 (CEI 45-104), tuttavia rimane applicabile fino al 13-04-2021.

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.
