Scope
NB/T 11139-2023 is the English-translated version of 矿用三维激光扫描仪.
NB/T 11139-2023 is the Chinese energy industry standard for three-dimensional laser scanners used in mines.
It defines ranging precision, the scanning field of view in the horizontal and vertical planes, and point cloud data, and then specifies product classification, technical requirements, test methods, inspection rules, and marking, packaging, transport and storage.
Laser safety is referred to GB 7247.1, explosion protection to the flameproof, increased safety and intrinsic safety parts of GB/T 3836, and enclosure protection to GB/T 4208.
Environmental testing for low and high temperature, damp heat, shock and vibration follows GB/T 2423, with the basic test methods of MT/T 210. Issued on 6 February 2023, it has applied since 6 August 2023.
