Ship equipment solar radiation test

The solar radiation test of ship equipment is suitable for ship equipment that is subject to thermal effects and photochemical effects caused by solar radiation during transportation and use to assess its corresponding environmental adaptability. The purpose of solar radiation testing of ship equipment is to determine the effects of solar radiation on ship equipment that is stored or used when exposed to sunlight.
Zhongke Testing Environmental Reliability Experiment Center has various ship equipment environmental testing equipment and solar radiation testing capabilities. It provides professional ship equipment solar radiation testing services for complete ship machinery, component equipment, and ship materials.

1. Heating effect.
Changes in solar radiation intensity can also cause components to expand or contract at different rates, which can cause dangerous stresses and damage the device's structure. In addition to the thermal effects of high-temperature tests, solar radiation may also produce these effects: stuck or loosened moving parts, reduced strength of welds and bonded parts, reduced accuracy or failure of connection devices, reduced sealing integrity, changes in the performance of electrical or electronic components, premature action of electrical contacts, etc.
2. Photochemical effect.
Ultraviolet rays in sunlight cause photochemical effects that may cause damage, such as fading of fabrics, cracking and fading of coatings, damage to natural and synthetic rubbers, and polymers.

1. Solar radiation intensity requirements:
Test level A: completely exposed to the open air, used for open-air equipment on ships.
Test level B: Illumination through glass windows, applied to cabin equipment exposed to sunlight.
2. Spectral energy distribution:
Divided into spectral areas: ultraviolet B, ultraviolet A, visible light, infrared
