摘要总结AI 辅助解读

本条款规范了容量不超过150升、最大压力不超过25 MPa的UN3468金属氢化物储存系统的运输包装要求。核心变更在于强制要求此类设备的设计、制造及测试必须符合ISO 16111:2018标准，仅允许在2026年12月31日前过渡使用旧版ISO 16111:2008(E)。此外，钢制或带钢衬复合压力容器必须带有“H”标记以应对氢脆风险，且再认证周期不得超过五年。该规定直接影响危险品出口美国的合规准入与单证审核。

The following packing instruction is applicable to transportable UN Metal hydride storage systems (UN3468) with pressure receptacles not exceeding 150 liters (40 gallons) in water capacity, and having a maximum developed pressure not exceeding 25 MPa. UN Metal hydride storage systems must be designed, constructed, initially inspected, and tested in accordance with ISO 16111:2018 (IBR, see § 171.7 of this subchapter), consistent with § 178.71(m) of this subchapter. Until December 31, 2026, UN Metal hydride storage systems may instead conform to ISO 16111:2008(E) (IBR, see § 171.7 of this subchapter). Steel pressure receptacles or composite pressure receptacles with steel liners must be marked in accordance with § 173.301b(f), which specifies that a steel UN pressure receptacle displaying an “H” mark must be used for hydrogen-bearing gases or other gases that may cause hydrogen embrittlement. Requalification intervals must be no more than every five years, as specified in § 180.207 of this subchapter, in accordance with the requalification procedures prescribed in ISO 16111:2018 or ISO 16111:2008.
