|Dust||1||Protected against solid objects Greater than 50mm. E.g. Hand.||Moisture||1||Dripping water shall have no harmful effect.|
|Dust||2||Protected against solid objects Greater than 12mm. E.g. fingers.||Moisture||2||Protected against dripping water when enclosure is tilted 15 degrees.|
|Dust||3||Protected against solid objects Greater than 2.5mm. E.g. tools.||Moisture||3||Protected against spraying water up to 60 degrees.|
|Dust||4||Protected against solid objects Greater than 1mm. E.g. wires.||Moisture||4||Water splashed from any direction shall have no harmful effect.|
|Dust||5||Ingress of dust is not totally protected but does no enter in sufficient quantities to harm equipment.||Moisture||5||Water hosed against the enclosure shall have no harmful effect. (Water jets)|
