Cisterne per il trasporto di merci pericolose - Cisterne metalliche a pressione - Progettazione e costruzione

La norma, aggiornata nel suo contenuto tecnico in modo sostanziale, specifica i requisiti minimi per la progettazione e la costruzione delle cisterne metalliche a pressione per il trasporto di merci pericolose su strada, ferrovia e mare, aventi una pressione massimo esercizio o di prova maggiore di 50 kPa (0,5 bar).

La norma comprende i requisiti per dispositivi di aperture, chiusure e di struttura, ma non comprende i requisiti delle attrezzature di servizio. Per le cisterne per il trasporto di liquidi criogenici, si applicano le UNI EN 13530-1 e UNI EN 13530-2.

This document includes requirements for openings, closures and structural equipment; it does not cover requirements of service equipment.

For tanks for the transport of cryogenic liquids, EN 13530 1 and EN 13530 2 apply. Design and construction of pressure tanks according to the Scope of this document are primarily subject to the requirements of RID/ADR, Subsections 6.8.2.1, 6.8.3.1 and 6.8.5, as relevant. In addition, the relevant requirements of RID/ADR, Table A, columns 12 and 13, to Chapters 3.2, 4.3 and Subsection 6.8.2.4 apply.

The paragraph numbers above relate to the 2017 issue of RID/ADR which are subject to regular revisions. This can lead to temporary non-compliances with EN 14025. This document is applicable to liquefied gases including LPG; however for a dedicated LPG standard see EN 12493. If not otherwise specified, provisions which take up the whole width of the page apply to all kind of tanks.
