Technical

IP & IK Ratings

The International Protection code, sometimes called the Ingress

Protection code, classifies the protection given by an enclosure

against the touching of live parts, contact with moving parts

and protection against the ingress of foreign solid bodies. It

additionally specifies protection against the harmful ingress of

moisture or liquids. Two digits are used to describe its protection

rating, called the IP code.

The IK code when applied to a luminaire indicates the degree of

protection against mechanical impact. The range of IK runs from

IK00 (no protection) up to IK10 protection to 20 joules. A joule is

the unit of work energy. A newton is the unit of force that causes

an acceleration of 1m/s/s to a mass of 1kg. 1J = 1N x 1m.

First Digit - Protection against solid objects

Second Digit - Protection against liquids

No protection

0 No protection

Protection against large sized bodies eg, hands

1 Protection against vertically falling drops of water

Protection against medium sized bodies eg, fingers

2 Protection against drops of water up to 15° from the vertical (drip proof)

Protection against small bodies, 2.5mm dia. or greater

3 Protection against rain falling up to 60° from the vertical (rain proof)

eg, tools, wires

Protection against very small bodies, 1mm dia. or greater

4 Protection against splashed water from any angle (splash proof)

Protection against harmful deposits of dust (dust proof)

5 Protection against jets of water from any angle (jet proof)

Complete protection against deposits of dust (dust tight)

6 Protection against water from heavy seas eg, water tight for marine deck

use

7 Protected against immersion for a defined period

8 Protected against immersion for an indefinite period
