Water projected in powerful jets no harmful effects. Test duration: 1 minute per square meter for at least 3 minutes
Water volume: 100 liters per minute (0.37 impgal/s) Pressure: 100 kPa (15 psi) at distance of 3 meters (9.8 ft)
Tools > 2.5mm
High voltage apparatus
It means this high voltage apparatus device can prevent solid particles > 1mm ingress in usual, but tools < 2.5mm could ingress with personnel against. And it has the best waterproof level below the soak requirement.
According to standard. The 1st digit ranged from 0 (no protect) to 6 (complete protect) degree marked solid particle protection. The 2nd digit ranged from 0 (none) to 8 (Immersion, 1 meter / 3 ft / 3 in or more depth). And the optional 3rd / 4th letter for other protections. Those 2 digits allowed to replace with the letter X when insufficient data has been gathered to assign a protection level.
There used to be another number ranged from 0 to 9 for impact resistance degrees before the optional letters. It was replaced by IK code in standard EN 62262.
