The protection classes and safety classes
Information on a luminaire withstanding the penetration of dust and water in accordance with IEC 60598 / VDE 0711.
Safety classes
Safety class I
luminaire provided with an earth connection.
Safety class II
the functional insulation. The luminaire has an additional protective insulation. Under fault conditions there are no dangerous voltage can reach metal parts which can be touched.
Safety class III luminaire supplied with low voltage (12V, 24V), the luminaire does not need to be earthed.
Impact Resistance
The use of Joules (Newton metres-Nm) has been common for many years. More recently an IK rating normally used for electrical enclosures and cabinets (IEC 62262:2002) has emerged as manufacturers apply it to their luminaires, as they also enclose electrical circuits.
| IK Rating | IK01 | IK02 | IK03 | IK04 | IK05 | IK06 | IK07 | IK08 | IK09 | IK10 |
|---|---|---|---|---|---|---|---|---|---|---|
| Joules of Energy | 0.15j | 0.23j | 0.35j | 0.5j | 0.7j | 1j | 2j | 5j | 10j | 20j |
Degree of protection
The Ingress Protection (IP) rating, or International Protection Code, classifies luminaires according to their protection against the ingress of dust, solid foreign bodies and water as an IP number system required by IEC 60529 and in accordance with IEC 60598.
Protection from solids (First number)
| IP1x | Protection against solid objects of 50 mm. diameter and greater than 50 mm. |
| IP2x | Protection against solid objects of 12 mm. diameter and greater than 12 mm. |
| IP3x | Protection against solid objects of 2.5 mm. diameter and greater than 2.5 mm. |
| IP4x | Protection against solid objects of 1 mm. diameter and greater than 1 mm. |
| IP5x | Complete protection against solid objects and harmful dust deposits (dust-proof) |
| IP6x | Complete protection against dust entry (dust-tight) |
Protection from water (Second number)
| IPx1 | Protection against vertical dripping water |
| IPx2 | Protection against dripping water when tilted up to 15° from vertical |
| IPx3 | Protection against spraying water or falling rain up to 60° from vertical |
| IPx4 | Protection against splashing water from any direction (splash-proof) |
| IPx5 | Protection against water jets from any direction (jet-proof) |
| IPx6 | Protection against heavy seas or powerful water jets |
| IPx7 | Protection against immersion (water-tight) |
| IPx8.m | Protection against submersion (submersion-proof) |
