ActiveGeometrical product specifications (GPS)—Systematic errors and contributions to measurement uncertainty of length measurement due to thermal influences
产品几何技术规范（GPS） 长度测量中温度影响引入的系统误差和测量不确定度来源
Application Summary AI generated
This standard specifies methods for evaluating and correcting systematic errors and quantifying measurement uncertainty contributions caused by thermal expansion and temperature variations in length measurements. It is applied in precision engineering and manufacturing contexts, such as dimensional inspection of mechanical components, calibration of gauges and measuring instruments, and quality control processes where accurate length measurements are critical under varying thermal conditions.
