Small craft. Electric fans1 Scope This International Standard specifies requirements and describes test methods for measuring the airflow of fans intended for use in engine compartments, galley areas and other spaces on small craft in which mechanical ventilation is desirable. It applies to electrically operated fans rated for less than 50 volts direct current (d. c.). Fans may be of the centrifugal or axial flow type.
