IP Grade

Waterproof & Dust specifications IEC60529 (International Electrotechnical Commission)) in order to identify the motor mechanical appliances of protection (IP rating) enacted. IP latter two figures, the left indicates dust levels, water level indicates the right. For example (IP45) indicate that: waterproof dustproof grade 4 grade 5. In addition, if only the IP standard indicates when the water level is written (IPx5) form. (X) indicates that no dust tests done, (IPx5) merely expressed waterproof rating of 5.
