What do the numbers in an IP Rating mean?

The tables below should help make sense of it:
|First Number||Second Number|
|Protection from entry of solid objects||Protection from entry of Liquids|
|0||No Protection||0||No Protection|
|1||Protection against objects larger than 50mm||1||Protection against drops of water falling vertically|
|2||Protection against objects larger than 12mm||2||Protection against drops of water falling vertically when fixture is tilted up to 15o|
|3||Protection against objects larger than 2.5mm||3||Protection against water falling as a spray at any angle up to 60o(rain)|
|4||Protection against objects larger than 1mm||4||Protection against splashes of water from any direction|
|5||Dust Protected||5||Protection from low pressure jet of water from any direction|
|6||Dust Tight||6||Protection from high pressure jet of water from any direction|
|7||Protection from submersion up to 1m|
|8||Protection from submersion beyond 1m|
Common IP Ratings:
|IP55||Dust Proof, Jet Proof|
|IP64||Dust Tight, Splash Proof|
|IP65||Dust Tight, Jet Proof|
|IP67||Dust Tight, Watertight|
|IP68||Dust Tight, Pressure Watertight|
