Bathroom Moisture Rating Zones: Understanding the IP Code

June 14, 2016

Original Post: Bathroom Moisture Rating Zones: Understanding the IP Code

 

Few moments in life are more cherished than those few minutes each day that we step into the shower. Whether you get to experience it in a luxuriously designed shower oasis, or in a pre-fab apartment shower-bath combo, when it comes to purchasing lighting for the bathroom, certain criteria must be followed that doesn't apply to other areas of your home.

 

The International Electrotechnical Commission (IEC) prepares and publishes International Standards for all electrical, electronic and related technologies. The IEC developed Ingress Protection (IP) codes that rate the protection against liquids and dust on electrical equipment and enclosures. These codes represent different forms of environmental influence, the first digit represents the degree of protection against dust (solids), and the second digit represents the degree of protection against liquids.

 

The 1st Digit : Ingress of Solid Objects

IP 0 = No protection

IP 1 = Protected against solid objects over 50mm e.g. hands, large tools.

IP 2 = Protected against solid objects over 12.5mm e.g. hands, large tools.

IP 3 = Protected against solid objects over 2.5mm e.g. wire, small tools.

IP 4 = Protected against solid objects over 1.0mm e.g. wires.

IP 5 = Limited protection against dust ingress (no harmful deposit).

IP 6 = Totally protected against dust ingress.

 

The 2nd Digit : Ingress of Liquid Particles

IP 0 = No protection

IP 1 = Protected against vertically falling drops of water or condensation.

IP 2 = Protected against falling drops of water, when the enclosure is tilted at an angle up to 15° from its normal position.

IP 3 = Protected against sprays of water from any direction up to an angle up 60° from its normal position.

IP 4 = Protected against splash water from any direction.

IP 5 = Protected against low pressure water jets from any direction. Limited ingress permitted.

IP 6 = Protected against high pressure water jets from any direction. Limited ingress permitted.

IP 7 = Protected against short periods of immersion in water.

IP 8 = Protected against long, durable periods of immersion in water.

IP 9 = Protected against close-range high pressure, high temperature spray downs.

 

Likewise, Underwriters Laboratories (UL) also has a rating for Wet, Damp, or Dry lighting. Euri Lighting uses both rating systems by IEC and UL for our products, and the grouping of the two ratings described below is loose. Please visit our product pages for specific ratings of our individual products.

 

By dividing the area of a bathroom into moisture zones, it is easier to make smarter choices on the level of protection needed for your lighting equipment.

 

 Zone 0 refers to the areas totally immersed in liquid, such as inside the bathtub, the bottom of the shower, the inside of the sinks and toilet bowl. If you are to install lighting in Zone 0, you will need to purchase products with a UL Wet Rating, or an IP67. Any fitting used in this zone must be low voltage, with 12v as the maximum.

 

 Zone 1 refers to the areas above the bath and shower to a height of 2.25m (7.38 ft) from the floor. A minimum Damp Rating, or IP45 is required, but it is highly recommended to go with a Wet Rating, or IP65. Most shower lights are rated at IP65.

 

 Zone 2 requires a minimum IP44 rating, or UL Damp Rating. This area refers to the areas stretching 0.6m (1.9  ft) outside the perimeter of the bath and shower, to a height of 2.25m (7.38 ft) from the floor. Zone 2 also includes the areas surrounding the sink within a 0.6m (1.9  ft) radius.

 

The following Euri Lighting products currently come with an IP65 Moisture Rating:

 

  • DLC-1000e

  • DLC-1020e

  • DLC-1040e

  • DLC-3000e

  • DLC-3020e

  • DLC-3001e

  • EP38-2000ew

  • EP38-2020ew

  • EP38-2050ew
