What Is IP Zoning
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 indicates 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.

Zone 0 | Inside the bath or shower. Any fittings used here must be SELV (max. 12V) and have a minimum rating of IPX7 (protected against immersion in water) |
1 | Above the bath or shower to a height of 2.25m. A minimum rating of IPX4 is required |
Zone 3 | The area stretching to 0.6m outside the bath or shower and above the bath or shower if over 2.25m. An IP rating of at least IPX4 is required |
Outside Zones | Anywhere outside zones 0, 1 & 2. Where water jets are not to be used for cleaning purposes, the general rules of BS7671 apply |
