National military standard rain procedure I~III test room Turntable bearing 100kg Auto Parts Test Equipment
Products Introduction:
The rain test room complies with the national military standard GJB150.8A-2009 program I rain and rain test, and is used for simulating dynamic operation of military equipment or electronic products in various intensity rain environments, rain test methods and main parameters of military equipment, and wind rain test and rain test can be realized in a test box.
Meet the reinforcement test of the military standard GJB150.8A-2009 program for the test of large (test piece size) equipment. When the rain and rain blowing device cannot be used, the program II shall be considered.The program does not simulate natural rainfall, but improves the credibility of equipment waterproofing.
Procedure III is applicable to equipment that usually prevents rain proof but may be exposed to dripping due to condensation or upper surface leakage.Dripping test has two variables: a) equipment encountered drops of water (generally condensate); b) equipment exposed to severe condensation or upper surface leakage.
Meet the standards:
Procedure I, procedure, procedure I I I test of the GJB150.8A-2009 standard.
