what does IP65 and IP20 stand for?
We usually see the‘IP rating’or Ingress Protection in the LED Display product advertising brochures,generally it defines the protection degree that the Sports Rental LED Screen product should meet for the outdoor or long-time usage.
LED screens must be able to work 24 hours a day and 7 days a week and withstand extremely bad weather.For manufacturers it is required that the LED screens meet the criterion for outdoor LED screens IP65,and for indoor LED screens IP20.So what do these criterions mean?
As defined in international standard IEC 60529,it classifies the degrees of protection provided against the intrusion of solid objects(including body parts like hands and fingers),dust,accidental contact,and water in electrical enclosures of the Sports Rental LED Screen.The standard aims to provide users more detailed information than vague marketing terms such as waterproof.
The first digit indicates the protection against dust.And"6"means Dust Tight,which means no ingress of dust and complete protection against contact.The second digit indicates the protection against liquids.And"7"means ingress of water in harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time(up to 1 m of submersion).
The 2 digits indicate the same parameter with above.But the letters are different.And the first"5"means Dust Protected:Ingress of dust is not entirely prevented,but it must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment;complete protection against contact.The second"5"means:Water projected by a nozzle against enclosure from any direction shall have no harmful effects.
