Section 12-E202. GENERAL DEFINITIONS
-
Insert new definitions in Section 202 of the Mechanical Code to read as follows:
ASME CODE. The Boiler and Pressure Vessel Code (ASME BPVC) published by the American Society of Mechanical Engineers as referenced in Chapter 15, Referenced Standards.
BOILER, HEATING. A steam or vapor boiler operating at pressures not exceeding 15 psig (103 kPa), or a hot water boiler operating at pressures not exceeding 160 psig (1103 kPa) and temperatures not exceeding 250 °F (121 °C).
BOILER, HOT WATER HEATING. 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 is operated at a pressure not exceeding 160 psig (1103 kPa) and a temperature not exceeding 250 °F (121 °C) at or near the boiler outlet.
BOILER, HOT WATER SUPPLY. A boiler completely filled with water that furnishes hot water to be used externally to itself at pressures not exceeding 160 psig (1103 kPa) and a temperature not exceeding 250 °F (121 °C) at or near the boiler outlet.
BOILER, MINIATURE. A power or high-temperature water boiler which does not exceed the following limits: 16 inches (406 mm) inside diameter of shell; 20 square feet (1.86 m2) of heating surface (not applicable to electric boilers); 5 cubic feet (0.142 m3) of gross volume exclusive of casing and insulation; and 100 psig (690 kPa) maximum allowable working pressure.
BOILER, PORTABLE. A boiler that is primarily intended for temporary location, where its construction and usage permits it to be readily moved from one location to another.
BOILER, POWER. A boiler in which steam or other vapor is generated at a pressure of more than 15 psig (103 kPa).
BOILER, UNFIRED STEAM. An unfired pressure vessel or system of unfired pressure vessels intended for operation at a pressure in excess of 15 psig (103 kPa) steam for the purpose of producing and controlling an output of thermal energy.
CERTIFICATE OF COMPETENCY. A certificate issued by the code official to a person who meets the qualifications for an insurance company inspector set forth in the Mechanical Code.
CERTIFICATE OF INSPECTION (For Chapter 10). A certificate issued for operation of a boiler or pressure vessel as required in the Mechanical Code.
EXISTING BOILER OR PRESSURE VESSEL INSTALLATION. A boiler or pressure vessel constructed, installed, placed in operation, or contracted for on or before the effective date of the Construction Codes.
EXTERNAL INSPECTION. An inspection made when a boiler or pressure vessel is in operation.
INSURANCE COMPANY INSPECTOR. A person employed or retained by a District of Columbia-licensed insurance company who holds a valid certificate of competency.
INTERNAL INSPECTION. An inspection that can reasonably be conducted on the internal and external surfaces of a boiler or pressure vessel while it is shut down and the manhole plates, handhole plates, or other inspection opening closures are removed.
NATIONAL BOARD. The National Board of Boiler and Pressure Vessel Inspectors.
NEW BOILER OR PRESSURE VESSEL INSTALLATION. A boiler or pressure vessel constructed, installed, placed in operation or contracted for after the effective date of the Construction Codes.
NONSTANDARD BOILER OR PRESSURE VESSEL. A boiler or pressure vessel that does not bear the ASME Code symbol stamp, the API-ASME Code symbol stamp or the stamp of any jurisdiction that has adopted a standard of construction deemed by the code official to be equivalent to the Mechanical Code.
OWNER OR USER (For Chapter 10). Any person, including firms or corporations, legally responsible for the safe installation, operation and maintenance of any boiler or pressure vessel within the District of Columbia.
POTABLE HOT WATER HEATER. A heater supplying potable water for commercial purposes in which the pressure does not exceed 160 psig (1103 kPa) and the temperature does not exceed 210 °F (99 °C).
STANDARD BOILER OR PRESSURE VESSEL. A boiler or pressure vessel which bears the ASME Code symbol stamp, the API-ASME Code symbol stamp, both the ASME and the National Board stamps or the stamp of another jurisdiction that has adopted a standard of construction deemed by the code official to be equivalent to the Mechanical Code.
Strike the definition of Smoke-Developed Index from Section 202 of the International Mechanical Code in its entirety and insert new definition of Smoke-Developed Index in Section 202 of the Mechanical Code in its place to read as follows:
SMOKE-DEVELOPED INDEX. A comparative measure, expressed as a dimensionless number, derived from measurements of smoke obscuration versus time for a material tested in accordance with ASTM E 84 or UL 723
Strike the definition of Third Party Certified in Section 202 of the International Mechanical Code in its entirety and insert new definition of Third Party Certified in Section 202 of the Mechanical Code in its place to read as follows:
THIRD PARTY CERTIFIED. Product or material for which a certification was obtained by the manufacturer indicating that the function and performance characteristics of such product or material have been determined by testing and ongoing surveillance by an approved third-party certification agency. Assertion of certification is in the form of identification in accordance with the requirements of the third-party certification agency.
Strike the definition of Third Party Tested in Section 202 of the International Mechanical Code in its entirety and insert new definition of Third Party Tested in Section 202 of the Mechanical Code in its place to read as follows:
THIRD PARTY TESTED. Product, material or system that has undergone successfully a procedure by which an approved testing laboratory provides documentation that such product, material or system conforms to specified requirements.
