MTT-
The spec you need is IEC-529. You can get the spec from Information Handling Service or any other source of industry standards.

IP rating refers to ingress protection rating. The first digit refers to the level of solids protection.
1=> 50mm
2= >12mm
3 =>2.5mm
4= >1mm
5 = Dust protected
6= Dust tight

Second digit refers to level of water protection

1= dripping water
2= angled dripping water, ie wind blown
3 sprayed water
4= splashed water
5=water jets
6=heavy seas
7=immersion
8 =indefinite immersion

Thus IP 54 is dust protected & splash protected, which is Ok for most electric motors, but may go to IP55
