From this test hydrant, a static pressure and a residual pressure will be measured. The other hydrant, known as the flow hydrant, is usually the nearest hydrant away from the test hydrant. The flow hydrant is fitted with a diffuser device containing a pitot tube that measures stagnation pressure in the middle of the stream while the hydrant is ...
The history of testing, inspection and certification services spans back several centuries. In the late 19th century, following the advent of the Industrial Revolution and the considerable risks involved with high-pressure steam boilers, specialized institutions emerged across Europe which carried out periodical inspections of such vessels to assess their overall condition as a precautionary ...
A fire test is a means of determining whether fire protection products meet minimum performance criteria as set out in a building code or other applicable legislation. Successful tests in laboratories holding national accreditation for testing and certification result in the issuance of a certification listing .

The user (most likely a fire department) attaches a hose to the fire hydrant, then opens a valve on the hydrant to provide a powerful flow of water, on the order of 350 kilopascals (51 psi); this pressure varies according to region and depends on various factors (including the size and location of the attached water main).
A fire sprinkler system is an active fire protection method, consisting of a water supply system providing adequate pressure and flowrate to a water distribution piping system, to which fire sprinklers are connected. Although initially used only in factories and large commercial buildings, systems for homes and small buildings are now available ...
Hydrostatic testing is the most common method employed for testing pipes and pressure vessels. Using this test helps maintain safety standards and durability of a vessel over time. Newly manufactured pieces are initially qualified using the hydrostatic test. They are then revalidated at regular intervals according to the relevant standard.
