10.4.1 Illuminance Measurement
For lighting and illumination technicians
Illuminance measurements are required for planning, installation,
testing and monitoring of lighting systems, as well as for defining
illumination conditions for hygienic, physiological, psychological
and/or safety reasons.
Areas of application, terminology, tasks, requirements and practi-
cal guidelines are set forth to a great extent in the DIN standards.
Definitions:
Universal illumination
Uniform illumination of a room which provides for nearly identical
visibility in all areas within the room.
Workstation oriented universal illumination
Universal illumination with fixed allocation of lamps to specific
workstations (refer to DIN V ENV 26385 for a definition of the
workstation).
Single workstation illumination
Illumination of individual workstations in addition to universal
illumination.
Practical Examples of Illuminance Measurements
• Planning and installation of illumination systems and monitor-
ing of such with regard to ageing, contamination and viability.
• Daylight in interior rooms (DIN 5034)
• Testing of emergency lighting (in accordance with paragraph 7
of the German Workshop Directive, illuminance must have a
value of at least 1 lux).
• Traffic illumination with street lights for vehicles and traffic
facilities (DIN 5044)
• Evaluation of headlights (DIN 5037)
• Gymnastics and play (DIN 18032, part 1)
• Sport facility illumination (DIN 67526-1)
• Illumination of construction sites, railroad yards, airport aprons
and other outdoor areas
• Floodlighting for buildings, towers and smokestacks
• Illumination of greenhouses and plants
Illumination with artificial light (DIN 5035)
This standard applies to the artificial illumination of interior rooms;
it applies analogously to the artificial illumination of outdoor areas,
in so far as they are used for the same purpose as the
corresponding interior rooms. In cooperation with all interested
groups, the standards committee has made every attempt to
devise the minimum requirements such that they are justifiable
from an illumination technology standpoint on the one hand, and
that they do not represent any unreasonable requirements for the
user on the other hand. In combination with ASR 7/3, the
standard bindingly specifies the recognized technical rules by
means of whose application the stipulations set forth in
paragraph 7, section 3 of the German Workshop Directive
(ArbStättVO) dated March 1975 are complied with.
