IEC TS 60825-19:20 24规定了当考虑平台相对于固定参考系的运动时，用于移动平台激光产品分类的速度相关最近人类接触点(VCPHA)。这预先假定移动平台的固有动力学危险产生了一个区域，在该区域中不会合理地预期人员将被定位。此外，它通过定义固定和移动孔来考虑相邻的移动平台。本文件适用于激光孔径在移动平台上的所有激光产品。激光产品有时用于移动平台。目前，标准IEC 60825-1:20 14仅考虑固定孔径；它没有解决发射孔安装在可以运动的平台(例如车辆)上的情况。不考虑平台运动的影响可能会导致对危险的评估过于严格。尽管在评估激光产品分类期间考虑平台的移动可以导致限制性较小的测量条件，但重要的是不要忽视，即使在其他移动平台上，也可能存在相对于被分类的移动平台激光产品以零或接近零的相对速度移动的孔。

IEC TS 60825-19:2024 specifies the velocity-dependent closest points of human access (VCPHA) for the classification of moving platform laser products when considering the movement of the platform with respect to a stationary frame of reference. This presupposes that the inherent kinetic hazard of the moving platform creates a zone in which persons would not be reasonably expected to be located. Additionally, it takes neighbouring moving platforms into account by defining stationary and moving apertures. This document is applicable to all laser products whose laser apertures are on a moving platform.
Laser products are sometimes used on moving platforms. Currently the standard IEC 60825-1:2014 considers only a stationary aperture; it does not address the situations where the emitting aperture is mounted on a platform, such as a vehicle, that can be in motion. Failure to consider the effects of the motion of the platform can result in overly restrictive assessment of the hazard.
Although accounting for a platform’s movement during the assessment of a laser product’s classification can lead to less restrictive measurement conditions, it is important not to overlook that there can be apertures, even on other moving platforms, moving at a relative speed of zero or close to zero with respect to the moving platform laser product being classified.
