Enclosure protection laboratory
This lab is the place for enclosure protection grade test and enclosure negative pressure seal test of the electrical equipment (lighting fixtures),test equipment is designed in accordance with GB4208 enclosure protection grade (IP code) standard,test equipments are all made of imported SUS316L stainless steel,this equipment can be tested according to GB 4208-4208 standard for protection grade test,can undertake four protection grade tests such as IPX4 splash-proof,IPX5 water spray resistance,IPX6 violent water spray resistance and IPX7 diving resistance,combined with equipped dust chamber,still can undertake IP5X dust and IP6X dust tight two protection grade tests.It can fully simulate the company's electrical products in the user site under all kinds of severe weather protection performance.Test parameters are shown in the following table:
Waterproofing test: if no other specified standard,the following conditions shall be regarded as the minimum acceptable requirements: generally speaking,if water is in,it shall not be sufficient to affect the normal operation or damage the safety of the equipment;the water does not accumulate on the insulating parts which may cause leakage and electric scars along the creepage distance; water does not enter live parts or windings that are not allowed to operate in a humid state; water does not accumulate near the cable head or into the cable.
Dust test:IP5X:after the test,observe the talc deposition amount and location,
if it is not enough to affect the normal operation or safety of the equipment like other dust,the test will be deemed as qualified.Unless special cases are specified in the relevant product standards,dust deposition is not allowed at the places where the creepage distance may lead to leakage and electrification.
IP6X: the product needs to be pumped under negative pressure,and there is no obvious dust deposition in the shell after the test,which means that the test is qualified.
