The Laser Illuminated Projector Association (LIPA) has released a pdf that outlines their purpose. Generally speaking, there are many international rules that require laser-based equipment to go through regulatory agencies which might make sense for other products (which might use focused light in the output), but don’t make sense for laser-based projectors (which use a diffuse light that substitutes for the xenon bulb.)
