IEC 62282-6-300:2012涵盖了微型燃料电池（MFC）燃料盒的互换性，以为各种MFC动力单元提供盒兼容性，同时保持MFC动力系统的安全性和性能。为此，该标准涵盖了燃料盒及其连接器设计。还包括燃料类型、燃料浓度和燃料质量。该标准还提供了避免不当燃料盒的误接的方法。本标准中还提供了验证是否符合燃料和燃料盒互换性要求的试验方法。与上一版相比的主要变化如下: -更新A型至D型可互换连接器，增加E型； -更新可互换连接器型式试验的程序、标准和图表，以确保结果准确和一致。

IEC 62282-6-300:2012 covers interchangeability of micro fuel cell (MFC) fuel cartridges to provide the cartridge compatibility for a variety of MFC power units while maintaining the safety and performance of MFC power systems. For this purpose, the standard covers fuel cartridges and their connector designs. Fuel type, fuel concentration and fuel quality are also covered. This standard also provides for the means to avoid the miss-connection of an improper fuel cartridge. Test methods for verifying the compliance with the interchangeability requirements for fuel and fuel cartridges are also provided in this standard. The main changes with respect to the previous edition are listed below:
- updates to Type A to D interchangeable connectors, addition of Type E;
- updates of the procedures, criteria and figures of the type tests for interchangeable connectors to ensure accurate and consistent results.
