C., the proposed change. Before a change is recommended, the Director, National Bureau of Standards, shall secure advice and consultation from public or private sources including particularly the household refrigerator manufacturing Industry and the Children's Bureau of the Department of Health, Education, and Welfare, and shall then forward such proposal with his recommendation to the Secretary of Commerce for such action as the secretary deems appropriate.
