Moisture and dust protection (IP)
For indication the level of the protection from environmental impact, IP code system is used according to IEC 529-89. Protection level is encoded as IP XY, where X – level of protection from solids and dust, Y – from moisture.

4 |
Protection from solidsØ > 1 mm |
Protection from water splashes randomly falling |
5 |
The penetration of dust doesn't cause disturbance of product (system) operability. |
Protection from water jet randomly disposing, Water jet from nozzle at 12.5 liter/min doesn't have any adverse impact |
6 |
No dust penetration |
Protection from strong water jet randomly disposing. Water jet from the nozzle at 100 liter-min doesn't have any adverse impact. |
7 |
Is not provided |
Protection from temporary flood. If the case is immersed to the depth from 0.15 to 1 m during 30 minutes, water in quantities harmful for internal devices, is not to penetrate in. |
8 |
Is not provided |
Protection from the water penetration during immersing to the depth determined by the producer. |
9 |
Is not provided |
Special protection determined by the producer |
You must know protection level of the equipment when you choose: crane scales, trade balances, data terminals, bar code scanners, video surveillance cameras, weigh detectors, weigh terminals etc.
