AASS

Acetic Acid Salt Spray
Access Ports
holes that can be placed in the side walls of a lab corrosion testing cabinet, through which
compressed air lines, water or hydraulic lines, electrical lines, or mechanical connections can be
routed; used to connect to samples being tested.
Acetic Acid
a mild acid, chemical formula C

, used as a corrosive fluid in some test methods, such as ASTM
G85 Annex 1 and GM 4466-P; also used in conjunction with
sodium chloride
in test methods BS7479
and ISO9227.
Acetic Acid Salt Spray (AASS)
a test method requiring a corrosive solution of
acetic acid
and
sodium chloride
,
such test methods include BS7479 and ISO9227.
Acid Rain Test
a test method that is intended to duplicate the conditions of outdoor exposure in an industrial area,
where rain rinses chemicals from the atmosphere.
Acrylic Cover
a clear cover for lab corrosion testing equipment, which sloping angle is designed to prevent
condensation from dripping onto samples, and which allows for viewing of ongoing test conditions.
Adjustable Cone
an inverted (point down) cone, which deflects the upward-rising fog from the
atomizer nozzle
,
and is the top of an
Omni-Fog Tower
; also catches any drops or droplets and allows them to drip back
into the
Internal Reservoir
, thus preventing splattering of test samples.
Adjustable Humidity
see
Variable Humidity
, also called
Controlled Humidity.
Air-actuated Cover
an option that provides a mechanical way to lift the cover of a lab corrosion testing cabinet
which, when connected through cabinets controls, allows the cover to be raised at specified times,
such as for access to samples, or to automatically create ‘lab ambient’ conditions in the
Exposure
Zone
.
Air Bubbler
a component for percolating incoming compressed air located at the base of the
Bubble Tower;
w
hen air passes through it, the air is separated into small bubbles, which increases the surface area of
air in contact with heated
DI water
, thus increasing both the temperature and the humidity of the air.
Air Compressor
a mechanical device that is used to create pressurized air.
Air Powered Cover Lifter
see
Air-Actuated Cover
.
Air Pressure Gauge
a gauge located on the
Bubble Tower
in Salt Fog cabinets and on the
Control Panel
of cyclic
cabinets, which shows the pressure of air at the top of the
Bubble Tower
.
Air Regulator
a device which allows a specific volume if air to pass, so that air pressure is maintained at a
desired level.
Air Relief Valve
a safety device located on top of the
Bubble Tower
with a setpoint to about 5 psi / 34 kPa above
the desired air pressure, which will open and allow air to escape if the air pressure exceeds the
setpoint.
Alarm
an error condition that cause a corrosion cabinet to stop operation; these are usually removed through
manual action by the operator after problem correction.
ASS
see
Acetic Salt Spray
.
Atomizer Nozzle
a small cylinder, made of acrylic resin, that combines compressed air and a fluid (salt solution,
water, electrolyte) and propels the mixture upward through the
Omni-Fog Tower
as a fog.
Automatic Solution Level Control
a system of level switches, solenoids, supply lines and a reservoir that
maintains a set level of fluid (salt solution, water, electrolyte) in the
internal reservoir
.
Back Pressure
in a drain line or fluid supply line, pressure that causes movement of fluid in the opposite direction
than which desired.
Bubble Tower
a vertical cylinder that is 3/4 full of heated water, through which compressed air is forced to make
the air humid; allows compressed air to atomize fluid (salt solution, water, electrolyte).
Bubble Tower Heater
a resistance heater submerged in water in the
Bubble Tower
.
Building Drain
a hole in the floor of a room, such as a laboratory, that is connected to a sewer system; intended
to remove fluids by gravity from the room or building; also called Gravity Drain.
