Fire extinguishers that are required to be returned to the manufacturer for recharging shall be hydrostatically tested

The pressure in a hydrostatic test of a cylinder shall be maintained for a minimum of________
seconds, but for no
less time than is required for complete expansion of the cylinder and to complete the visual examination of the cylinder.

The hydrostatic test label of low pressure cylinders shall include

The hydrostatic test interval for the following types of extinguishers is years:

Dry chemical and dry powder hose assemblies requiring a hydrostatic pressure test shall be tested at
or at service pressure, whichever
is higher.

Drying equipment is required to dry all nonwater types of fire extinguishers that have passed the hydrostatic test.
True False

Where a fire extinguisher cylinder or shell has corrosion that has caused pitting, including pitting under a removable nameplate or nameband assembly,

For high pressure cylinders and cartridges passing a hydrostatic test, the month, year, and the DOT identification number shall be stamped into the cylinder in accordance with the requirements set forth by

The equipment for testing low pressure cylinders includes a flexible connection for attachment to the test pump. It shall be provided with necessary fittings to test through the fire extinguisher

Before hydrostatic testing, all
extinguishers shall have the valve removed from the cylinder and replaced with a suitable test bonnet or adapter.

All stored-pressure fire extinguishers shall be hydrostatically tested at the factory pressure not to exceed
the normal operating pressure.

The exception to the standard service pressure ratio for testing carbon dioxide fire extinguishers is that carbon dioxide fire extinguishers having cylinder specification
ICC3 shall be tested at
psi.

The equipment for testing low pressure cylinders includes
for personnel protection.

Where fire extinguisher shells, cylinders, or cartridges fail a hydrostatic pressure test, they shall be

Fire extinguishers having aluminum cylinders or shells suspected of being exposed to temperatures in excess of
shall be removed from service and
subjected to a hydrostatic test.

Where a calcium chloride type of extinguishing agent was used in a stainless steel fire extinguisher,

A hydrostatic test pump, hand-operated or power-operated, shall be capable of producing not less than percent of the test pressure.

Cartridge- or cylinder-operated dry chemical and dry powder types of fire extinguishers shall be hydrostatically tested at

For hydrostatic testing, all types of extinguishers except shall have all traces of extinguishing
agents removed from inside of the extinguisher before filling with water.

A hydrostatic test shall be performed on fire extinguisher hose assemblies

Fire extinguisher shells of the low pressure type that pass a hydrostatic test shall have the test information recorded

Any person holding a fire extinguisher license may perform hydrostatic testing.

Hose assemblies passing a hydrostatic test do not require recording.
True False

AIL
wheeled extinguishers shall
have pressure relief devices removed prior to hydrostatic testing.

Hose assemblies of carbon dioxide fire extinguishers that require a hydrostatic test shall be tested

Dry chemical, dry powder, water, foam, and halogenated agent discharge hose assemblies requiring a hydrostatic pressure test shall be tested at or at service pressure, whichever is higher.

Nitrogen cylinders or cartridges used for inert gas storage used as an expellant for wheeled fire extinguishers shall be tested every years.

itrogen cylinders and carbon dioxide cylinders used ith wheeled fire extinguishers shall be tested at e service pressure as stamped into the cylinder.

In addition to the visual examination required for high pressure cylinders prior to testing, an internal examination shall be made prior to the hydrostatic test.
True False

Ill air shall be vented prior to hydrostatic testing to revent

A complete internal and external visual examination shall be conducted following any hydrostatic test.
True False

Nitrogen cartridges and carbon dioxide cartridges used as an expellant for hand portable fire extinguishers that have DOT or TC markings shall be hydrostatically tested or replaced according to the requirements of DOT or
TC, with the following exception(s):

Fire extinguishers shall be hydrostatically tested at intervals not exceeding those specified in table 5-2 of
NFPA 10, with the following exception(s):

Carbon dioxide fire extinguishers shall be tested at the service pressure as stamped into the cylinder.

The hydrostatic testing of
fire
extinguishers having an externally mounted gas cartridge shall have the cartridge and cartridge receiver removed and a suitable plug inserted into the opening.

NFPA 10, 5-1.3 states,
"If, at any time, a fire extinguisher
shows evidence of corrosion or mechanical injury, it shall be hydrostatically tested.
