ANSI B11.25-2022
Safety Requirements for Large Machines
This standard applies to two specific subsets of machinery: Machine types that would be covered by machine specific, “type C” B11 standards, but would be excluded by any size limitation in the scope of those standards; Machines that, by the nature of the size of the workpiece, tooling, or process travels, require entry into the work envelope to perform normal process tasks.
