Environmental conditions and tests for electrical and electronic
equipment Part 4: Climatic loads clause 5.5 salt spray test. Equipment Overview
Corrosion of protected and unprotected metallic materials is
influenced by many environmental factors, which mainly depend on
the type of metallic material and the type of environment. It is
impossible to design a laboratory accelerated corrosion test
chamber that includes all environmental factors that affect
corrosion resistance. Therefore, the laboratory test is designed by
simulating the factors that play a major role in the corrosion of
metallic materials. This equipment is designed to simulate and
increase the effects of the environment on metallic materials
exposed to an outdoor atmosphere that is contaminated with salt and
can accelerate corrosion. The equipment includes a test method for
cyclically exposing the sample to salt spray, dry, hot and humid
environments. This equipment test is a comparative test, and the
test results cannot predict the long-term results of the corrosion
resistance of the same metal material used under this environmental
condition. However, this method can still provide valuable
information on the relative performance of materials exposed to
salt pollution like the test conditions. Compared with traditional
accelerated corrosion tests, such as neutral salt spray test (NSS),
acetic acid salt spray test (AASS), and copper accelerated acetic
acid salt spray test (CASS), the biggest advantage of this
equipment test is that it can better Reproduces corrosion that
occurs outdoors in salt-contaminated environments. 1.3 The equipment has temperature-humidity-heat alternating salt
spray compound test chamber with temperature and humidity
adjustment function is used to test various performance indicators
and quality management of accessories under alternating compound
conditions such as high temperature, humidity, dryness, and salt
spray. Technical Parameters

temperature of 35°C, saturated barrel temperature of 47°C, spray
test time of 5% salt water concentration from 1min to 999h can be
set arbitrarily, and then in the damp heat test at a temperature of
40°C±2°C, relative humidity 93%RH±3%RH, the test time can be set
arbitrarily from 1min to 999h; the cycle can be set arbitrarily
from 1 to 999 times. Then, let it stand for 1min to 999h under
standard environmental conditions with a temperature of 23°C±2°C
and a relative humidity of 50%RH±5%RH, which can be set
arbitrarily. B. Dry and wet compound salt spray test conditions: at an ambient
temperature of 35°C, a saturated barrel temperature of 47°C, and a
spray test time of 5% salt water concentration from 1min to 999h,
which can be set arbitrarily; dry under the condition that the
relative humidity is equal to or lower than 30%RH For the test, the
test time can be set arbitrarily from 1min to 999h; in the humid
and hot environment with a relative humidity greater than 95%RH,
the test time can be set arbitrarily from 1min to 999h; then return
to the first step of the salt spray test; the cycle can be set
arbitrarily from 1 to 999 times. C. NSS salt spray test, AASS acetic acid salt spray test, CASS
copper accelerated acetic acid salt spray test, damp heat test,
drying test, standard large climate environment test conditions or
other combined test conditions can be carried out independently. |
