Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. [1] " Nominal" refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – 2-inch nominal steel pipe" consists of many varieties of steel pipe with the only criterion being a 2.375-inch (60.3 mm) outside ...
NFPA 1963, which defines the vast majority of fire hose couplings in existence, and ANSI-ASME B1.20.7, which defines garden hose thread (sometimes used by wildland fire fighting crews) along with (non-tapered) iron pipe thread, and ANSI B26, FIRE-HOSE COUPLING SCREW THREAD FOR ALL CONNECTIONS HAVING NOMINAL INSIDE DIAMETERS OF 2 1 ⁄ 2, 3, 3 1 ...
5-inch (13 cm) flex suction hose with Storz fittings, mounted on an engine. Flexible suction hose (Flex suction or suction hose), not to be confused with hard suction hose in U.S., is a specific type of fire hose used in drafting operations, when a fire engine uses a vacuum to draw water from a portable water tank, pool, or other static water source.
The hydraulic calculation procedure is defined in the applicable reference model codes such as that published by the US-based National Fire Protection Association (NFPA), [2] or the EN 12845 standard, Fixed firefighting system – Automatic sprinkler systems – Design, installation and maintenance.

NFPA 750 [19] defines water mist as a water spray with a droplet size of "less than 1000 microns at the minimum operation pressure of the discharge nozzle". The droplet size can be controlled by adjusting the discharge pressure through a nozzle of a fixed orifice size.
A gas hydrant would have a yellow background instead of a white one for fire hydrants. All of them have large central T with the installation identification on top of it – an "H" or older "UH" is located in the ground, a "OH" is above ground, followed by the pipe inner diameter in millimeters (with a small 80 mm in residential areas).
