Subpart 14-1 - Definitions
Section 14-1.1 - Definitions

(a) Alteration means a change in a boiler that substantially alters the original design and that requires consideration of the effect of the change on the original design. Alteration does not include the addition to a boiler of nozzles smaller than an unreinforced opening size.

(b) Approved means, in respect to a device or material: in compliance with a subsisting resolution of approval adopted by the Commissioner; in respect to action by the commissioner: made the subject of a resolution of approval.

(c) ASME Code means the boiler and pressure vessel code published by the American Society of Mechanical Engineers.

(d) Boiler means a closed vessel in which water is heated, steam is generated, steam is superheated, or any combination thereof, under pressure or vacuum for use externally to itself by the application of heat from combustible fuels, electricity, or any other source, but shall not include a device or apparatus used solely to heat water for a hot water supply system. The term boiler shall include the apparatus used by which heat is generated, and all controls and devices related to such apparatus or to the closed vessel. The term boiler also shall include fired units for heating or vaporizing liquids other than water where these units are separate from processing systems and are complete within themselves.

(e) Boiler external piping means piping within the scope of ASME Code section I and which requires ASME Code stamping as specified in section I and this Code.

(f) Certificate of competence means a certificate issued to a boiler inspector by the department.

(g) Commissioner means the Commissioner of Labor of the State of New York.

(h) Component means a constituent part of a boiler assembly.

(i) Condemned, with reference to a boiler, means declared to be unsafe and having an applied stamping designating its condemnation.

(j) Defect means a condition which may directly or indirectly cause a boiler to be or become a source of danger to any person by reason of fire, explosion, leakage, electricity or ionizing radiation.

(k) Defective boiler means one which as an assembly includes a defect, or a boiler which is not provided with all required controls and devices in good operating condition.

(l) Department means the Department of Labor.

(m) External inspection means an inspection made while the boiler is in operation.

(n) Fusion welding means the melting together of filler metal and base metal, or of base metal only, which results in coalescence.

(o) High temperature water boiler means a boiler completely filled with water intended for operation at pressures in excess of 160 psi or temperatures in excess of 250° Fahrenheit.

(p) Hot water heating boiler means a boiler in which no steam is generated, from which hot water is circulated for heating purposes and then returned to the boiler, and which operates at a pressure not exceeding 160 psi or a temperature of 250° Fahrenheit at or near the boiler outlet.

(q) Hot water supply boiler means a boiler completely filled with water that furnishes hot water to be used externally to itself at pressures not exceeding 160 psi at temperatures not exceeding 250° Fahrenheit at or near the boiler outlet.

(r) Incompetence means conduct which evidences a lack of ability to discharge a duty required to protect the health, safety and welfare of the public, lack of knowledge of the fundamental principles of inspection services or an inability to apply those principles, or failure to maintain competency in the current practices and methods applicable to inspection services and the rules of New York State.

(s) Inspector means a boiler inspector who holds a valid certificate of competency issued by the department.

(t) Installed means, in respect to a heating system boiler as a vessel, placed in a fixed operating location and connected to the heat distributing system; in respect to an unfired pressure vessel, placed in a fixed operating location. The term does not include a reassembly not involving a change of location.

(u) Insurance company means a company which has been licensed in this State to write boiler insurance and which is actively engaged in writing such insurance for the general public.

(v) Internal inspection means an inspection made when the boiler is shut down and handholes and manholes or other inspection openings are opened or removed for inspection of the interior as required by the inspector.

(w) Low pressure boiler means a steam boiler on which the safety valves are set at pressures not exceeding 15 psi.

(x) Maximum allowable working pressure means the maximum gage pressure permissible at the top of a completed vessel in its operating position for a designated temperature.

(y) Maximum allowable working temperature means the maximum temperature at or near the outlet of a hot water boiler, measured in degrees Fahrenheit, at which the boiler may be safely operated.

(z) Miniature boiler means a power boiler or high temperature water boiler which does not exceed any of the following limits:

(aa) National Board means the National Board of Boiler and Pressure Vessel Inspectors, Columbus, Ohio.

(bb) Owner means the owner or a lessee of a boiler or unfired pressure vessel.

(cc) Portable boiler means an internally fired boiler primarily intended for temporary location and whose construction and usage is of a movable nature.

(dd) Post-1917 installations means installations made on or after January 1, 1918.

(ee) Power boiler means a boiler in which steam or other vapor is generated at a pressure of more than 15 psi.

(ff) Pre-1918 installations means installations made before January 1, 1918.

(gg) Relief valve means an automatic pressure relieving device actuated by the static pressure upstream of the valve which opens further with the increase in pressure over the opening pressure. Note: A relief valve is used primarily for liquid service.

(hh) Repair means work necessary to restore a boiler to a safe operating condition.

(ii) Safety relief valve means an automatic pressure actuated relieving device suitable for use as either a safety valve or a relief valve, depending upon application.

(jj) Safety valve means an automatic pressure relieving device actuated by the static pressure upstream of the valve and characterized by full-opening pop action. Note: A safety valve is used for gas or vapor service.

(kk) Secondhand vessel means a boiler or unfired pressure vessel that has changed location subsequent to the original installation.

(ll) Standard means, with reference to a boiler or unfired pressure vessel, constructed and stamped in accordance with the ASME Code.

(mm) Unfired pressure vessel means a container for the containment of internal or external pressure which may be obtained from an external source or by the application of heat from a direct or indirect source, or any combination thereof, but excluding:
