To illustrate IP zoning regulations, we show a bathroom area divided up into areas or ‘ZONES’ which are classified using the numbers 0, 1 & 2. Luminaires are then assigned an ‘IP RATING’ which indicated how much protection they provide against ingress of water and other particles. Each zone has a minimum IP requirement that must be met if a fitting is to be installed in this area.
“IP” (“Ingress Protection”) RATING
Protection against ingress of foreign bodies e.g. tools, dust, fingers, ect.
Protection against ingress of liquids i.e. IP44 is protected against solid objects greater than 1mm and water sprayed from all directions.
Protected against solid objects greater than 50mm (e.g. accidental touch by hands)
Protection against vertically falling drops of water (e.g. condensation)
Protected against solid objects up to 12mm (e.g. fingers)
Protection against direct sprays of water up to 15 degrees from vertical
Protected against solid objects greater than 2.5mm (e.g. tools & wires)
Protection against direct sprays of water up to 60 degrees from vertical
Protected against solid objects greater than 1mm (e.g. small tools & wires)
Protection against water sprayed from all directions - limited ingress permitted
Protected against dust, limited ingress (e.g. no harmful deposit)
Protected against low pressure jets of water from all directions - limited ingress permitted
Totally protected from dust
Protected against high pressure jets of water (use on ship deck) - limited ingress permitted
Protected against the effects of immersion between 15cm and 1m
Protected against long periods of immersion under pressure
