La Norma EN/IEC 60071-1: 2019 si applica ai sistemi in corrente alternata trifase con una tensione massima per le apparecchiature superiore a 1 kV. Questa Norma, che specifica la procedura per la scelta delle tensioni nominali di tenuta per l'isolamento fase-terra, fase-fase e longitudinale dell'apparecchiatura e delle installazioni di questi sistemi, fornisce gli elenchi delle tensioni normalizzate di tenuta da cui vengono scelte le tensioni di tenuta nominali. Questa scelta deve essere associata, al solo scopo del coordinamento dell’isolamento, alla tensione più alta per l'apparecchiatura. I requisiti riguardanti la sicurezza delle persone non sono coperti da questo documento.
La Norma in oggetto sostituisce completamente la Norma CEI EN 60071-1:2008-06, che rimane applicabile fino al 12-09-2022.
La presente Norma riporta la traduzione completa della EN IEC 60071-1; la versione inglese è riportata nel fascicolo 17301E di febbraio 2020.

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.
