ActiveGeometrical product specifications (GPS)—X-ray three dimensional size measuring machines—Part 4: Evaluation of uncertainty in measurement
产品几何技术规范（GPS） X射线三维尺寸测量机 第4部分：测量不确定度评定
Application Summary AI generated
This standard specifies the method for evaluating the measurement uncertainty of X-ray three-dimensional size measuring machines, including the analysis of error sources such as beam hardening, detector noise, and workpiece geometry. It is applied in industrial metrology and quality control, particularly for non-destructive testing of internal and external dimensions in precision manufacturing sectors like aerospace, automotive, and electronics. The standard ensures consistent and reliable uncertainty assessment when using computed tomography for dimensional measurements.
