This document, SN EN 13445-1:2021, provides the foundational framework for understanding unfired pressure vessels and is critical for professionals in the Fluid Systems industry. It addresses terminology, definitions, design, and manufacturing guidelines for vessels operating at pressures above 0.5 bar gauge, while also being applicable for lower pressures and vacuum conditions. The standard serves as an essential resource for ensuring safety and compliance in the creation of unfired pressure vessels.

=== SECTION 1 ===

What SN EN 13445-1:2021 covers

SN EN 13445-1:2021 outlines the general principles and definitions necessary for the design and construction of unfired pressure vessels. The standard applies to vessels with a maximum allowable pressure greater than 0.5 bar gauge but can also be relevant for those operating at lower pressures, including vacuum. It explicitly excludes riveted vessels, those made from lamellar cast iron, multilayered, autofrettaged, or pre-stressed vessels. Additionally, it provides guidance for specific applications, such as transportable vessels and those intended for nuclear use, ensuring that appropriate safety measures are taken based on risk assessments.
