Le présent document spécifie les exigences de fonctionnement pour les récipients cryogéniques fixes, isolés sous vide, conçus pour une pression maximale admissible supérieure à 0,5 bar. Il peut également être utilisé comme guide pour les récipients conçus pour une pression maximale admissible inférieure à 0,5 bar.
<p>ISO 21009-2:2015 specifies operational requirements for static vacuum insulated vessels designed for a maximum allowable pressure of more than 50 kPa (0,5 bar). It may also be used as a guideline for vessels designed for a maximum allowable pressure of less than 50 kPa (0,5 bar).</p> <p>ISO 21009-2:2015 applies to vessels designed for cryogenic fluids specified in ISO 21009‑1.</p> <p>Static cryogenic vessels are often partly equipped by the manufacturer, but may be installed or re-installed by another party, such as the operator, user or owner.</p> <p>NOTE 1 For the installation of these vessels, additional requirements can apply; these are defined in specific regulations.</p> <p>NOTE 2 Some requirements of this standard can be covered by local regulations, e.g. safety distances, occupational safety and health. Where there is a conflict between the requirements of this International Standard and any applicable local regulation, the local regulation always takes precedence.</p>
