Section 8: Definitions
S . D
APPLIANCE (EQUIPMENT) – Any device which utilizes gas as a fuel or raw material to produce light, heat, power,
refrigeration or air conditioning.
APPROVED – Acceptable to the authority having jurisdiction.
AUTHORITY HAVING JURISDICTION – e organization, office or individual responsible for “approving” equipment,
an installation or procedure.
BONDING (BONDED) – e permanent joining of metallic parts to form an electrically conductive path that ensures
electrical continuity and the capacity to conduct safely any current likely to be imposed. As per the National Electrical Code.
CAPACITY, FLOW – As used in this standard, the amount of a specified gas that will flow through a specific length and
configuration of tubing, a manifold, fitting or other component at a specified pressure drop in a fixed period of time.
CONCEALED GAS TUBING – Gas tubing, which, when in place in a finished building, would require removal of
permanent construction to gain access to the piping.
CONNECTOR, GAS APPLIANCE – A factory-fabricated assembly of gas conduit and related fittings designed to convey
gaseous fuel, and used for making connections between a gas supply piping outlet and the gas to an appliance. It is equipped
at each end for attachment to standard taper pipe threads.
CONTINUOUS METALLIC SYSTEMS – Potential pathways for electricity to ground i.e. metallic chimney and vents,
metallic ducting and piping, insulated or jacketed electrical cables and wires.
DIRECT BONDING – Bonding, as above, where the electrical connection is made using a clamp and wire at the piping
connected directly to the existing electrical grounding system. Refer to Section 4.10 Electrical Bonding of FlashShield™
CSST.
EFFECTIVE GROUND-FAULT CURRENT PATH – An intentionally constructed, permanent, low impedance electrically
conductive path designed and intended to carry under ground fault conditions from the point of a ground fault on a wiring
system to the electrical supply source.
EQUIVALENT HYDRAULIC DIAMETER (EHD) – A theoretical size, which reflects the hydraulic performance of the
tubing. It is not true physical measurement.
EXPOSED GAS TUBING – Gas tubing which will be in view in the finished structure.
FUEL GAS – A commonly distributed gas used for fuel such as natural gas, manufactured gas, undiluted liquefied petroleum
gas (vapor phase only), liquefied petroleum gas-air mixtures of these gases (includes propane and butane).
GAS UTILIZATION EQUIPMENT – Any device that utilizes gas as a fuel or raw material or both.
INCHES OF WATER COLUMN ("WC) – Method of pressure measured in inches of water column by a manometer or
pressure gauge. Commonly used in the gas industry when the pressure is less than 1 PSI.
LEAK TEST SOLUTION – A solution of commercial leak-testing fluids may be used. e use of soap buds or household
detergents and water is not considered a satisfactory leak-test fluid for a bubble test, because of a lack of sensitivity due to
masking by foam. e fluid should be capable of being applied free of bubbles so that a bubble appears only at a leak. e
fluid selected should not bubble except in response to a leak.
