Established in 1896, NFPA's mission is to reduce the worldwide burden of fire and other hazards on the quality of life by providing and advocating consensus codes and standards, research, training, and education.
A thick, wet mixture of aggregate and portland cement mixed in proportions of two parts aggregate to one part portland or plastic cement, dashed onto a monolithic surface to improve the mechanical key for subsequent plaster coats.
Industry:Fire safety
A thermal oil heating system that is designed to operate with the heated oil below its atmospheric boiling point.
Industry:Fire safety
A thermal imaging system (camera), which can be vehicle-mounted, designed to detect thermal energy.
Industry:Fire safety
A test performed by the flow and measurement of water from one hydrant and the static and residual pressures from an adjacent hydrant for the purpose of determining the available water supply at that location.
Industry:Fire safety
A test of a piping system using high velocity flows to remove debris from the piping system prior to it being placed in service.
Industry:Fire safety
A test of a closed piping system and its attached appurtenances consisting of subjecting the piping to an increased internal pressure for a specified period of duration to verify system integrity and leak rates.
Industry:Fire safety
A test instrument designed to continually check the balanced and unbalanced impedance from each line of an isolated circuit to ground and equipped with a built-in test circuit to exercise the alarm without adding to the leakage current hazard.
Industry:Fire safety
A test designed to determine the amount of underground water available in a given field and proper well spacing to avoid interference in that field. Basically, test results provide information concerning transmissibility and storage coefficient (available volume of water) of the aquifer.
Industry:Fire safety
A terminal, lug, or other provision provided on some equipment cases (enclosures) to connect the conductive portion of the enclosure to the equipment-grounding conductor.
