Test Background
The main impacts of high-temperature storage environments on marine instruments are: Storage at too high a temperature and for too long a time will accelerate the degradation of the equipment and damage the packaging of the equipment. Many malfunctions of marine instruments are caused by various physical and chemical changes in the body and surface. When the ambient temperature increases, the rate of chemical reactions is greatly accelerated, the failure process is also accelerated, and defective instruments will be exposed.
Zhongke Testing Reliability Experiment Center has environmental testing capabilities for various marine instruments, and provides professional high-temperature storage testing and other environmental testing services for marine instrument products.
Scope of tests
Marine instruments are classified according to different environmental conditions of use and are divided into four categories:
1. Instruments for shore stations: such as marine instruments installed and used on coastal stations, offshore fixed platforms and islands.
2. Instruments for ships and buoys: such as marine instruments used on various types of ships, buoys and other mobile offshore platforms.
3. Underwater instruments: such as marine instruments or sensors used in seawater.
4. Satellite and aeronautical instruments: The environmental testing of such instruments should adopt other environmental testing standards based on the characteristics of the environmental conditions in which they are used.
test temperature
Unless otherwise specified, the high temperature storage test temperature of marine instruments should be selected from the following values:
a) (55±2)℃;
b) (70±2)℃;
Note: 70 ℃ is only suitable for extreme storage environments in North Africa, the Middle East, Pakistan and India, the southwestern United States, northern Mexico, and around the equator.
