5.6.2.1 Test method
The sinusoidal vibration test shall be performed in accordance with IEC 60068-2-6 with the equipment under test mounted on the vibration test equipment in accordance with IEC 60068-2-47 except as indicated in the following. Mount the equipment under test on the vibration test equipment in its normal mounting configuration and subject to a resonance search — without power applied to the equipment — followed by a period of vibration at each resonance frequency detected (dwell periods). For the purposes of this document, a resonance frequency is one where the acceleration, as indicated by the reference accelerometer, would increase to at least twice the reference level were it not for the effect of the closed loop acceleration control system. Perform the test in three orthogonal axes sequentially. The equipment under test shall be checked for impaired function and examined for loose parts and visible cracks at the conclusion of each test phase.
5.6.2.2 Test limits/dwell times
The resonance searches, and dwell periods, shall be conducted at the acceleration values specified in Table 7, with the frequency being swept from 10 Hz to 2 000 Hz to 10 Hz at a sweep rate of 1 octave/ min. The acceleration value range is similar to the acceleration values listed for relevant installation locations specified in ISO 16750-3. See Table 7 for severity levels and dwell times.
5.7.1 Test method
The corrosive atmosphere test shall be conducted in accordance with IEC 60068-2-11. Mount the equipment under test in its normal mounting configuration in the test chamber and expose to the corrosive atmosphere for the durations according to Table 8. Inspect the equipment for corrosion, without rinsing, immediately after the test and, again, 100 h after the test, also without rinsing, and monitor the equipment for impaired function at these same times. During the 100 h duration the equipment shall be in an environment of 25 °C and <50 % relative humidity.
5.11.1 Test method
The solar radiation test shall be performed in accordance with IEC 60068-2-5 except as indicated herein. Subject the equipment under test to alternating UV exposure and humidity exposure for 1 500 h. The UV exposure time shall be 8 h ± 6 min at (60 ± 5) °C with ambient humidity, and the humidity exposure time shall be 4 h ± 6 min with condensing humidity at (50 ± 5) °C. Check the equipment for impaired function and visually examine for ultraviolet-induced degradation after the test. UV radiation in the wavelength range of 280 nm to 400 nm at a power density of 60 W/m 2 ± 15 W/m 2 shall be applied. NOTE Only equipment which is exposed to sunlight in use need be tested.
5.12.1 Test method
The readability of display devices test shall be performed with a radiation source with spectral energy distribution shown in of IEC 60068-2-5:2018, Table 1, and in accordance with IEC 60068-2-5, except as indicated in the following. Subject the display device under test, in its normal operating configuration, to radiation from the solar radiation source such that the light levels at the centre of the display device and at four locations around the perimeter of the display device are within 5 % of the relevant severity level specified in Table 10. Monitor the display device for readability as defined by the user.
