5. 详细要求
5.1 系统、子系统和设备测量参数
5.1.1 参数估计
设计机构应评定所有要求测量和试验的系统、子系统和设备参数，以确保正确的系统或设备操作和准确度，并确保满足预期设计目的。
5.1.1.1 关联顺序
参数的评定将描绘系统、子系统和设备内部和它们之间的逻辑顺序，识别要求测量和查证的参数。
a. 要求测量和查证的系统参数，用来确保系统的正确操作，系统要求的任务可以完成。
b. 要求测试和测量的子系统参数，在集成到整个系统中时，用来确保子系统的交换性和正确操作。
c. 要求测试和测量的设备参数，当作为系统和子系统的一部分，和连接到系统和子系统时，确保设备的可交换性和正确操作。
华译网上海翻译公司曾经翻译过大量有关系统、子系统和设备测量参数资料文件。Beijing Chinese Subtitling Translation Service Agency has translated many technical documents about System, subsystem, and equipment measurement parameters.
5. DETAILED REQUIREMENTS
5.1 System, subsystem, and equipment measurement parameters.
5.1.1 Assessment of parameters. The design activity shall assess all system, subsystem, and equipment parameters that require measurement or testing to ensure proper system or equipment operation and accuracy, and to ensure intended mission goals are met.
5.1.1.1 Sequence of relationship. This assessment of parameters shall portray the logical sequence of relationship within and between the system, subsystem, and equipment, and identify the parameters requiring measurement and verification.
a. System parameters require measurement and verification to ensure proper operation of the system so the mission requirements of the system can be accomplished.
b. Subsystem parameters require test and measurement to ensure interchangeability and proper operation of the subsystem when integrated into the complete system.
c. Equipment parameters require test and measurement to ensure interchangeability and proper operation of the equipment when used as part of or connected with the system or subsystem.
