《GB/T 16857.10-2022产品几何技术规范（GPS） 坐标测量系统（CMS）的验收检测和复检检测 第10部分：激光跟踪仪》由TC240（全国产品几何技术规范标准化技术委员会）归口，主管部门为国家标准委。
Introduction
Core requirements of laser tracker testing standards
| Test items | Technical indicators | Test methods |
|---|---|---|
| Shape detection error | ≤PForm.Sph.1×25:SMR:LT,MPE | 25-point spherical fitting |
| Length measurement error | ≤EVol:0:LT,MPE | 41 reference test lengths |
Analysis of key technology evolution
This standard introduces Laser tracker's double-sided test method detects positioning error (LDia.2×1:P&R:LT) by rotating the horizontal angle 180°, and its sensitivity is 3 times higher than that of traditional methods.
New combined sensor (SRC/ODR) test specifications are added, requiring the positioning error of multiple detection systems to be ≤LDia.n×25::MPS.LT,MPE.
Implementation recommendations
- Acceptance testing should include at least 15m of synthetic detection length testing (Appendix C)
- Re-testing frequency is recommended to be performed every 500 working hours or after a major vibration event
- Dual-sided testing is preferred for periodic verification (Appendix E.5.1)
