ISO 21009-2:2006规定了最大允许压力超过0.5 bar（50 kPa）的静态真空绝缘容器的操作要求。它也可用作最大允许压力小于0.5 bar（50 kPa）的容器的指南。 ISO 21009-2:2006适用于为EN 13458-1和EN 13458-2中规定的低温流体设计的容器。 静态低温容器通常部分由制造商装配，但可能由另一方（如操作员、用户或所有者）安装或重新安装。因此，ISO 21009-2:2006的部分范围（包括安装、投入使用、检查、填充、维护和应急程序）与EN 13458-1、EN 13458-2和EN 13458-3重叠。

ISO 21009-2:2006 specifies operational requirements for static vacuum insulated vessels designed for a maximum allowable pressure of more than 0,5 bar (50 kPa). It may also be used as a guideline for vessels designed for a maximum allowable pressure of less than 0,5 bar (50 kPa). ISO 21009-2:2006 applies to vessels designed for cryogenic fluids specified in EN 13458-1 and EN 13458-2. 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. For this reason, some of the scope of ISO 21009-2:2006, which includes installation, putting into service, inspection, filling, maintenance and emergency procedure, overlaps with EN 13458-1, EN 13458-2 and EN 13458-3.
