SEC. 13. Definitions of terms. — (a) Mechanical engineering. — A person shall be deemed to be practicing mechanical engineering or rendering mechanical engineering service within the meaning and intent of this Act, who shall, for a fee, salary or other reward or compensation paid to himself or to another person, or even without such reward or compensation, render professional mechanical engineering service in the form of consultation, investigation, valuation, planning, design, or preparation of specifications or estimates for, or take charge of, supervise or undertake the construction, erection, installation or alteration of, or render engineering service in connection with the manufacture, sale, supply or distribution of, or to manage, operate, tend or maintain any mechanical equipment, machinery or process, for any mechanical works, project or plant; or who shall, by means of signs, cards, advertisement or in any other way, offer to practice mechanical engineering service, use, assume or advertise any title or description tending to convey the impression that he is a professional engineer, or mechanical plant engineer, or junior mechanical engineer, or certified plant mechanic, or that he is engaged in the practice of mechanical engineering as defined in this Act. (b) The term "mechanical equipment, machinery or process," as used in this Act, shall include steam engines, internal combustion engines, boilers, turbines, crushers, mills, mixers, pumps, compressors, cranes, conveyors, hoists, elevators, pipe lines, line-shafting, etc., but shall not include motor vehicles, street cars, locomotives, steamships, motorships, airplanes, and similar machinery used as means of transportation, nor shall include generators, motors, transformers, rectifiers, or similar machinery or apparatus primarily electrical in nature, nor mechanical or mill supplies, hardware and similar articles. (c) The term "mechanical works, project or plant," as used in this Act, shall include steam plants, internal combustion engine plants, hydraulic power plants, pumping plants, refrigerating plants, mills, shops, factories, foundries, shipyards, etc., containing any mechanical equipment, machinery or process, driver by steam, internal or external combustion fuel, electricity, air, gas, water, heat, chemicals or other prime movers : Provided, however, That the provisions of this Act shall not apply to any mechanical works, project, or plant of less than twenty (20 H.P.) horsepower, nor to mechanical works, projects or plants of the United States army or navy, nor to such mechanical works, projects or plants of the national, provincial, municipal, or city governments as may be declared exempted by the Secretary of Public Works and Communications. (d) The term "horsepower," as used in this Act, shall mean the mechanical unit of power equal to five hundred fifty (550 ft. lb.) foot-pounds per second, and shall apply to the normal horsepower rating of the engine, motor, turbine, or other prime mover, at full load, as stamped on the name plate attached to the prime mover. In the absence of a name plate rating, the horsepower rating of a prime mover, for purposes of compliance with the provisions of this Act, shall be determined by reference to the manufacturer or local agent or by calculation or other method of determination made by a reputable registered professional mechanical engineer. Such determinations of horsepower rating shall be accepted as correct until otherwise determined by the Board of Mechanical Engineering Examiners, whose decision shall be final. (e) Capacity of works, project, or plant. — The horsepower rating of a mechanical works, project or plant, for purposes of compliance with the provisions of this Act, shall be the total horsepower of all engines, motors, turbines, or other prime movers installed for use in such works, projects or plant, whether in operation or not, and without regard to the number or capacities of the mechanical equipment, machineries or processes receiving power from or intended to be driven by such prime movers.
