National Army Standard GJB150A Rain Test Knowledge?

The national military standard GJB150A rain test is a test designed specifically for military equipment, aimed at evaluating their performance in potentially rainy environments. This experiment is not aimed at corrosion testing or the adaptability of aircraft windshield wipers, but focuses on the waterproof and anti-seepage capabilities of the equipment casing and its working efficiency after being rained on.

The core purpose of the national military standard GJB150A test is to verify the effectiveness of the equipment protective cover by simulating different rainfall conditions, such as windy rainstorm, dripping and waterproof test, to ensure that the equipment performance is not affected during rainfall, and to check whether the equipment maintains normal operation after raining, and to check whether the rainwater drainage system operates well.

The specific test conditions for the national military standard GJB150A include: minimum rainfall intensity of 10cm/h, raindrop diameter between 0.5 and 4.5mm, horizontal wind speed of at least 18m/s, and duration ranging from 30 to 40 minutes. In the experiment, the equipment needs to be tested under conditions that are 10 ℃ Higher than the temperature of rainwater, using water from local sources. The drip test simulates the possible condensation or leakage of water that rainproof equipment may encounter.

The GJB150A rain test is usually conducted in a rain test chamber, which can simulate natural rainfall but exclude the influence of factors such as strong winds and high temperatures. This process aims to provide a reliable evaluation basis for the waterproof performance of military equipment.
