激光产品安全 第19部分：移动平台激光产品

[中文适用范围]： 本部分IEC 60825规定了移动平台激光产品分类时，相对于静止参考系考虑平台运动的人体可接近最近点(VCPHA)。假设移动平台的固有动能危害形成了一个区域，在该区域内人员不应合理预期存在。此外，通过定义静止和移动孔径，考虑了相邻移动平台。 本文件适用于所有激光孔径位于移动平台上的激光产品。 [外文原描述]： 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.
