Test Background
On the one hand, the constant heat and humidity test can simulate the impact of the heat and humidity environment on the product in actual use. On the other hand, it can also identify the moisture-proof ability of the product and evaluate the safety and reliability of the product under high temperature and high humidity conditions. The constant humidity and heat test of fire-fighting electronic products can determine the adaptability of fire-fighting electronic products in various usage scenarios for use, transportation, placement or storage in high temperature and high humidity environments.
Zhongke Testing Reliability Experiment Center has environmental testing capabilities for various fire-fighting electronic products, and provides professional constant humidity and heat test services for fire alarm equipment, alarm valves, fire communication equipment and other fire-fighting electronic products.
Scope of tests
1. Fire alarm equipment: fire alarm triggering devices, fire alarm control devices, fire alarm devices, fire linkage control equipment; etc.
2. Alarm valve: wet alarm valve, dry alarm valve, deluge alarm valve, pre-action device, delayer, hydraulic sensor, hydraulic alarm bell, etc.
3. Fire communication equipment: fire alarm dispatcher, fire command and dispatch equipment, fire vehicle dynamic management device, etc.
Test method
1. Constant humidity and heat operation test: The test temperature for Level 0 and Level I is 40±2℃, the relative humidity is 93±3%, and the duration is 4d. No testing is required for other grades.
2. Constant humidity and heat durability test: The test temperatures for levels 0, Ⅰ, Ⅱ, Ⅲ and Ⅳ are all 40±2℃, the relative humidity is 93±3%, and the duration is 21d.
