Standard and Safety

 

Information on a luminaire withstanding the penetration of dust and water in accordance with EN 60598 / VDE 0711.

 

Symbols


 

ligman ce

The CE mark for product conforms to the requirements of EEC directives and compulsory to indicate LVD, EMC and ballast efficiency conformity.

 

ligman F mark

F Mark (mounting surface), luminaire meet the requirements in accordance with EN60598-1 and suitable for mounting on normally combustible surfaces but has come to end in 04/2012.

 

 

Safety Classes


ligman class I

Safety class I luminaire provided with an earth connection.

 

ligman class II

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.

 

ligman class III

Safety class III luminaire supplied with low voltage (12V, 24V), the luminaire does not need to be earthed.

 

 

Protection Classes


Degree of protection The International Protection (IP) classifies luminaire 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)

 

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 (EN 50102:1995) has emerged as manufacturers apply it to their luminaires, as they also enclose electrical circuits. This chart compares both ratings:
