Low Noise ESS Chamber With Cable Port Lighting Device Fast Cooling
Rate Inner Size is 225L
Application:
Temperature adaptability test under the condition of rapid change,
or gradient for electrical, electronic, instruments and other
products or spare parts, particularly applies to environmental
stress screening test (ESS)
Environmental stress screening (ESS) refers to the process of
exposing a newly manufactured or repaired product or component
(typically electronic) to stresses such as thermal cycling and
vibration in order to force latent defects to manifest themselves
by permanent or catastrophic failure during the screening process.
The surviving population, upon completion of screening, can be
assumed to have a higher reliability than a similar unscreened
population.
ESS can be performed as part of the manufacturing process or it can
be used in new product qualification testing.
Sample requirements
In order to make your test data more realistic and effective,The
test chamber must be used reasonably while meeting the following
principles:
The total mass of the load is not more than 80Kg per cubic meter of
studio volumeThe total volume of the load cannot be greater than
1/5 of the working chamber volume
On any section perpendicular to the dominant wind direction,The sum
of the load areas should be no more than 1/3 of the cross-sectional
area of the working chamber.Do not block the flow of airflow when
the load is placed.
Meet the standards:
GB/T 2423.1-2008(IEC68-2-1)Test A:Low temperature test method.
GB/T 2423.2-2008(IEC68-2-2)Test B: High temperature test method.
GJB360.8-2009(MIL-STD.202F)High temperature life test.
GJBl50.3-2009(MIL-STD-810D)High temperature test method.
GJBl50.4-2009(MIL-STD-810D)Low temperature test method.
