ISO 8274:2005规定了在规定的操作循环次数后，用于确定门套和车窗开启部件机械耐久性的方法。 ISO 8274:2005适用于在正常运行条件下以完整组件形式安装的任何窗户或任何门，无论其结构材料和操作系统如何。测试中涉及的部件包括框架、开口元件（包括任何二次元件）和所有基本硬件，包括操作装置。它不包括任何额外的紧固件，如支柱或车厢挂钩，也不包括任何独立安装的限流器。 在ISO 8274:2005中，假设运行周期使铰链、撑杆、天平和其他机构等辅助部件发生移动。

ISO 8274:2005 specifies the method to be used to determine the mechanical durability of doorsets and the opening parts of windows after a defined number of operating cycles. ISO 8274:2005 applies, whatever their construction materials and operating systems, to any window or any door in the form of complete assemblies in normal operating conditions. The parts concerned in the testing are the frame, the opening elements (including any secondary elements) and all essential hardware, including operating devices. It does not include any additional fasteners such as pegstays or cabin hooks, nor any independently installed restrictor. In ISO 8274:2005, it is assumed that the operating cycle imparts movement to ancillary items such as hinges, stays, balances and other mechanisms.
