Overhead mounting of luminaires, lighting accessories, and other portable devices: specification and practice
This standard covers specifications for the primary and secondary mounting devices for portable stage and studio luminaires and accessories, and for similarly fastened special effects machines. The standard offers guidance on how to properly affix these mounting devices. This revision relaxes the labeling requirements and makes it clear that environmental factors (e.g., heat, UV, and salt spray) need to be considered for all mounting devices.
