ISO 21009-2:2015规定了设计用于最大允许压力超过50kPa（0.5bar）的静态真空隔热容器的操作要求。它也可以用作设计用于最大允许压力小于50kPa（0.5bar）的容器的指南。 ISO 21009-2:2015适用于ISO 21009-1中规定的用于低温流体的容器。 静态低温容器通常由制造商部分配备，但也可能由另一方（如运营商、用户或所有者）安装或重新安装。 注1:对于这些容器的安装，可以适用其他要求；这些在具体规定中有定义。 注2:本标准的一些要求可以由当地法规涵盖，例如安全距离、职业安全和健康。如果本国际标准的要求与任何适用的当地法规之间存在冲突，则始终以当地法规为准。

This document specifies operational requirements for static vacuum insulated vessels designed for a maximum allowable pressure of more than 50 kPa (0,5 bar). It can also be used as a guideline for vessels designed for a maximum allowable pressure of less than 50 kPa (0,5 bar). This document applies to vessels designed for cryogenic fluids specified in ISO 21009-1. Static cryogenic vessels are often partly equipped by the manufacturer, but can be installed or re- installed by another party, such as the operator, user or owner. NOTE 1        For the installation of these vessels, additional requirements can apply. NOTE 2        Some requirements of this document can be covered by local regulations, e.g. safety distances, occupational safety and health. NOTE 3        Additional requirements can apply to the operation of large scale and field-fabricated vessels.
