Protection degrees

According to the intended use lightings have to be equipped with various protection from ingression of water, dust or solid debris.

The labelling of the Protection Class starts with the code letter IP for "Ingress Protection". Following are two code numbers which, according to IEC 60529:1989 + A1:1999 / DIN EN 60529:1991 + A1:2000, determine in the

  • First number - Protection grade for shock-proof-protection and protection from inclusion
    The protection of persons from contact with or approach to activ parts as well as contact with moving parts inside the housing, as well as protection for the device from ingression of solid debris

  • Second number - Protection grade for water protection
    The protection of the operating agents inside the housing from the damaging ingression of water

and are established according to international unitarily defined testing procedures

Examples Advanced Protective System

IP65
= dust-tight and protected from jet water
IP66 = dust-tight and protected from strong jet water
IP67 = dust-tight and protected from immersion
IP68 = dust-tight and protected from submerging
