ISO 20826:2006规定了汽车液化石油气（LPG）容器的设计和试验技术要求，该容器将永久连接到使用汽车液化石油气（LPG）作为燃料的机动车上。 技术要求包括设计标准、施工和工艺要求、标记和重新鉴定程序。 ISO 20826:2006还涵盖了在生产和性能验证期间对汽车气体容器进行的所有试验，包括其频率。此外，还对改变设计时要进行的试验提出了具体建议。

ISO 20826:2006 specifies the technical requirements for the design and the testing of automotive Liquefied Petroleum Gas (LPG) containers, to be permanently attached to a motor vehicle which uses automotive LPG as a fuel. The technical requirements cover the design criteria, the requirements on construction and workmanship, the marking and re-qualification procedures. ISO 20826:2006 also covers all tests, including their frequencies, to be carried out on autogas containers, during production and performance verification. Specific recommendations are also given on the tests to be carried out when changing the design.
