Illumination at the Workplace
Nominal illumination of at least 200 lx is required for
continuously occupied indoor workstations, unless
another value is required due to operational or
optical, physiological reasons.
In rooms or indoor areas which are continuously
occupied by personnel, nominal illumination of at
least 100 lx is required.
Planning Values and Minimum Values
The nominal illumination value should be multiplied
by a factor of 1.25 for planning purposes.
The mean, arithmetic illumination value at the work-
place may not have a value of 0.8 times less than
the nominal illumination value, independent of the
aging factor of the lighting system. However, illumi-
nation at any given workstation may never have a
value of less than 0.6 times the nominal illumination
value.
DIN 5035 Part 2, Illumination with Artificial Light
Under the heading “Recommended Values for
Indoor and Outdoor Work Areas”
This standard includes an extensive table which
classifies types of work areas and activities, illumina-
tion values, the color of the light, characteristic color
rendition levels and classifications for the limitation
of direct glare. Important notes concerning special
requirements for lighting systems are included in an
additional column, for example, under which cir-
cumstances additional illumination at any single
workstation would be recommended, or even
required.
A table with recommended values for outdoor work
areas has also been added since the version issued
in October, 1979. In addition, characteristic color
rendition levels have been updated to correspond to
the classifications set forth in DIN 5035 part 1.
