Fireworks and firecrackers alternating humidity and heat test

The alternating humidity and heat of fireworks and firecrackers refers to the changes of fireworks and firecrackers in the high temperature and high humidity stage, low temperature and high humidity stage, temperature and humidity change stage and low temperature and high humidity maintenance stage of the alternating humidity and heat test. The alternating humidity and heat test of fireworks and firecrackers can determine the adaptability of the product to use and storage under humid and heat conditions where temperature cycles change and condensation occurs on the product surface.
Zhongke Testing and Reliability Experiment Center has the capabilities of environmental testing and reliability performance testing of various fireworks and firecrackers, and provides professional alternating heat and humidity testing services for fireworks and firecrackers.

Fireworks and firecracker products such as firecrackers, spray flowers, rotating types, lift-off types, spitting beads, toys, fireworks, stand fireworks, combination fireworks, etc.

1. The severity level of the alternating moist heat test for fireworks and firecrackers is determined by the combination of high temperature and the number of test cycles.
2. Select the severity level from the following combinations:
a) High temperature: 40℃
Test period: 2d, 6d, 12d, 24d, 56d.
b) High temperature: 55℃
Test period: 1 d, 2 d, 6 d
