Environmental test chambers replicate environmental
conditions such as high temperature and humidity, allowing engineers
to evaluate the effects that environmental changes have on products placed
within the chamber. An environmental test chamber evaluates product quality
and identifies flaws and weaknesses. Environmental testing falls under
two categories: climatic and mechanical. Climatic testing evaluates the
effects of natural environmental conditions such as temperature, humidity
and precipitation upon an object but at an accelerated rate. Mechanical
testing evaluates the effects of causal environmental conditions such
as vibration and shock upon an object. The information obtained from
an environmental test chamber is used to improve products before they
are marketed to the public.
Environmental test chambers are utilized in all industries, from automotive
to engineering and construction to medical, pharmaceutical, food processing
and packaging. Manufacturers test such items as cars, cigarettes, makeup,
medicine and medical instruments. There is a growing demand by customers
to have extended warranties and maintenance on products. Manufacturers
would be at high risk in offering these long-term warranties and service
contracts without test data to back up product performance guarantees.
Some manufacturers in industries where there is no pressure to prove
long-term reliability may be tempted to forgo the thousands of hours
required to obtain good test results, but reputations are won or lost
based on product performance, no matter what the product may be.
Environmental test chambers test products in a variety of ways, depending
on the product application. THB (Temperature/Humidity/Bias) testing is
one of the most common tests used for integrated circuit chips, because
the test chambers can hold 1851/4F/851/4C and 85% relative humidity condition
while bias loads are applied to the samples. The HAST (Highly Accelerated
Stress Test) uses high temperature (over 2121/4F/1001/4C), high relative
humidity (about 85%) and high atmospheric pressure conditions (up to
4 atms) to test products, such as integrated circuits. The HAST greatly
decreases the time needed to achieve useful test results, especially
in evaluating non-hermetic packaging of solid state equipment in humid
conditions. High temperature
chambers are used to assess potential product
failure such as damage, junction thermal resistance increase and depolymerization.
Products are subjected to temperatures of about 3021/4F/1501/4C for more
than 1,000 hours, after which electrical measurements are taken. Mixed
flowing gas chambers subject products to a mixture of pollutant gases
in a controlled temperature and humidity environment in order to assess
the damage to a product after long-term use in office and light to heavy
industrial settings.
Terms regarding thermal shock testing are often used incorrectly. Liquid-to-liquid
thermal shock is a process in which a product is alternately dipped in
non-toxic, noncombustible, chemically inert and low viscosity fluids
maintained at a specific temperature. Air-to-air, or two-zone, thermal
shock is the transferring of a product from a hot chamber to a cold chamber
or some other sudden change in air temperature, and vice versa. Sometimes,
in a transfer, there is an intermediate step in which the product is
exposed to room temperature conditions, which is called three-zone thermal
shock. Simply changing the air as quickly as possible in a single chamber
is more accurately referred to as thermal cycling or stress screening.
Before investing in an environmental test chamber for thermal shock testing,
be sure to have a clear definition of the requirements; otherwise, it
is very easy to purchase the wrong equipment.

Types of Environmental Test Chambers and Environmental
Test Chambers Manufacturers
Agree
chambers can produce fast temperature
changes of 41-104˜F (5-40°C)
per minute, even with large loads. Vibration test systems can be
integrated within agree chambers,
as they have removable floors.
Altitude chambers test the effects of low
pressure on an object and are capable of replicating low-pressure environments
found at altitudes of
up to 200,000 feet above sea level.
High Altitude Simulation (HAS) chambers replicate
environmental extremes that an airplane typically endures when in operation.
Humidity Chambers are
able to simulate a variety of humidity conditions in order to test
the effects of humidity on an object. Used for specific testing in industrial
and biotechnology applications.
Mixed Flowing Gas (MFG) chambers are
used to expose electronic equipment to a mixture of pollutant gases in
an
environment in which the temperature
and humidity are controlled.
Reach-in chambers often contain shelves
and other amenities for easy storage and user convenience.
Salt spray or fog chambers test
the corrosion resistance of an object. The object usually hangs from
a rod while the
chamber introduces a salty
residue, which creates a foggy atmosphere, although the object remains
visible throughout the process.
Temperature chambers test
the effects of temperature on an object. Temperature cycling is performed
alone or in conjunction with other tests, such as altitude and vibration
tests.
Thermal cycling or stress screening
chambers involve
the subjection of an object to extreme changes in temperature within
a single chamber
in which the temperature alternates between cold and hot for a given
number of cycles.
Thermal shock chambers initiate automatic
changes between two compartments, in which one compartment contains an
extremely cold environment and one
compartment contains an extremely hot environment. The rapid transference
of the object between these two compartments of extreme temperatures
causes a shock to the object.
Thermotron chambers are used for thermal
and dynamic testing and have shock and vibration capacity.
Vacuum chambers are chambers from which
almost all matter, especially air, has been removed.
Vibration chambers apply
shock vibrations of varying frequencies to an object, including the
bumping, shaking and
bouncing of an object, and
can be administered in conjunction
with temperature and humidity testing. Vibration chambers have sensors
that perceive and monitor the object’s
reaction to the vibration.
Walk-in chambers vary in size and can usually accommodate one or more persons.
Walk-in chambers are useful when testing large objects and performing batch testing.
Environmental Test Chambers and Environmental Test
Chambers Manufacturers Terms
Absolute Humidity – The amount of water vapor,
or moisture, in a unit of air.
Absolute Vibration – The measurement of an object’s vibration
in comparison to a fixed point in space.
Accelerated Life Testing – The subjection of a product to stress
during the development phase in order to gauge the quality of the product.
The stress applied to the product often exceeds that which the product
would sustain during normal use.
Accelerated Stress Testing – The subjection of a product to stress
after production in order to identify production flaws before the product
reaches retailers and consumers.
Aggravated Testing – The process of applying greater stress to
an object than that which the object would sustain during normal use,
the purpose of which is to identify guidelines by which the product may
be used.
Air-To-Air Thermal Shock – Also called “two-zone thermal
shock,” this process is the transferring of a product from a hot
chamber to a cold chamber or other sudden changes of the air temperature.
Ambient Environment – The given temperature and humidity content
of an indoor (internal) or outdoor (external) environment.
Atmospheric Pressure – The amount of force the atmosphere exerts
upon the earth’s surface, measuring 14.7 psi at sea level.
Batch Testing – A test procedure in which multiple items are tested
at the same time.
Burn-In – The hastening of a product’s aging process through
the continuous operation of the product, usually at higher than moderate
temperatures, in order to evaluate product quality.
Calibration – The process of comparison between the current operation
of an object or a system and the operating standards of that object or
system. Calibration determines the efficiency of an object and identifies
errors and the manner in which the system can improve.
Corrosion – The gradual deterioration of a metal caused by oxidation
or chemical reaction.
Critical Frequency – The frequency level at which point the destruction
of the object subjected to such frequency begins.
Damping – Decrease in the vibration of an object.
Dew Point – The temperature of a given unit of saturated (containing
the maximum amount of water vapor) air.
Dry Room – An environmental chamber in which the humidity level
remains below a 14° F/-10° C dew point.
Environment – The internal and external conditions, regardless
of the source, which affect a given object. The environment includes
temperature, humidity, electricity, precipitation, etc.
Environmental Stress Screening – The determination of the working
efficiency of an object or system through the identification of the effects
of thermal changes upon the object or system.
Frequency – The rate of movement, measured in cycles, of a wave
within a set time frame, usually one second. Frequency is often measured
in hertz (Hz), which equals one wave cycle per second.
Highly Accelerated Life Test (HALT) – A test that assesses the
lifetime of a product, reduces its development cycle time and increases
confidence in the life-cycle reliability of the product.
Highly Accelerated Stress Test (HAST) – Product reliability test
in which an object is subjected to high temperature, humidity and pressure.
HAST has also come to be called Autoclave or Pressure Cooker Test (PCT).
Hermetic – The airtight sealing of an object.
Life Cycle Testing – The subjection of a product to stress comparable
to that which the product will sustain during use in order to determine
product quality.
Liquid-To-Liquid Thermal Shock – Alternately immersing an object
in hot and cold liquids.
Product Recovery Time – The recovery time of a physical product
after it has been subjected to testing. Product recovery time is dependent
upon the location of the sensor in the load.
Psi (Pounds Per Square Inch ) – Unit that measures the amount of
pressure applied to an object.
Relative Humidity – The ratio of the current amount of water vapor
in a given unit of air at a given temperature to the greatest amount
of water vapor the unit of air could hold at that temperature.
Relative Vibration – The measurement of an object’s vibration
in comparison to a fixed point on the object.
Saturation Humidity – The maximum amount of water vapor a given
unit of air can hold at a given temperature. Air becomes saturated when
relative humidity reaches 100%.
Stress – Condition or force applied to an object that may impair
the object’s quality and performance.
Temperature/Humidity/Bias (THB) Test – Product reliability test
in which an object is subjected to high humidity under a constant temperature.
Test time greatly exceeds that of HAST test time.
Thermal Cycling – Subjecting an object to extreme changes in temperature
within a single environmental chamber.
Thermal Shock – Stress sustained by an object as a result of rapid
temperature changes.
Three-zone Thermal Shock – Moving
the object from a hot to a cold chamber and vice versa, with an intermediate
step of exposure to room
temperature.
Transfer Time – The amount of time it takes for an object to be
moved from one chamber to another.
Upstream Recovery Time – Also called “downstream recovery
time,” this is the time required for the air temperature to recover
in the new zone. Upstream recovery time can be measured in the air stream
prior to or following the test load.
Vibration – Motion of an object around a position of equilibrium.
