The Commissioner may expand the scope of any such experiment or demonstration project to include any group of applicants for benefits under the program established under this subchapter with impairments that reasonably may be presumed to be disabling for purposes of such demonstration project, and may limit any such demonstration project to any such group of applicants, subject to the terms of such demonstration project which shall define the extent of any such presumption.
(b) Requirements 
The experiments and demonstration projects developed under subsection (a) of this section shall be of sufficient scope and shall be carried out on a wide enough scale to permit a thorough evaluation of the alternative methods under consideration while giving assurance that the results derived from the experiments and projects will obtain generally in the operation of the disability insurance program under this subchapter without committing such program to the adoption of any particular system either locally or nationally.
(c) Authority to waive compliance with benefits requirements
