标准范围
ISO 21013-3:20 06提供了单独的计算方法，用于确定以下每个指定条件下所需的缓解质量流量。在正常真空下具有完整保温系统（外夹套+保温材料）的真空保温容器；环境温度下的外套；内容物温度在泄压下。具有隔热系统（外套+隔热材料）的真空隔热容器在正常真空下完好无损；环境温度下的外套；内容物温度在泄压压力下的内容物；压力建立系统的压力调节器以全电位运行。隔热系统仍在原位但失去真空的真空隔热容器，或隔热系统完好无损的非真空隔热容器；环境温度下的外套；内容物温度在泄压压力下的内容物；真空或非真空隔热容器，其隔热系统完全或部分保持在适当位置，但在真空隔热容器的情况下失去真空，并被火吞没；内容物在泄压温度下的内容器。带有绝缘系统的容器完全失去并被火吞没。在没有为适用条件提供适当计算方法的情况下，需要采用基于完善的理论物理科学的良好工程实践来确定所需的质量流量。
ISO 21013-3:2006 provides separate calculation methods for determining the required mass flow to be relieved for each of the following specified conditions.
- Vacuum-insulated vessels with insulation system (outer jacket + insulating material) intact under normal vacuum; outer jacket at ambient temperature; inner vessel at temperature of the contents at the relieving pressure.
- Vacuum-insulated vessels with insulation system (outer jacket + insulating material) intact under normal vacuum; outer jacket at ambient temperature; inner vessel at temperature of the contents at the relieving pressure; pressure regulator of the pressure build-up system functioning at full potential.
- Vacuum-insulated vessels with insulation system remaining in place but with loss of vacuum, or non-vacuum-insulated vessels with insulation system intact; outer jacket at ambient temperature; inner vessel at temperature of the contents at the relieving pressure; vacuum or non-vacuum-insulated vessels with insulation system remaining fully or partially in place, but with loss of vacuum in the case of vacuum-insulated vessels, and fire engulfment; inner vessel at temperature of the contents at the relieving pressure.
- Vessels with insulation system totally lost and fire engulfment.
