TÜV certificate ID:0000025994 "Ergonomically tested"
TÜV certificate ID:0000025994 "Ergonomically tested" prescribes the distance of control elements from
the table, the user and each other. Furthermore, it defines a broad adjustment range for the eyepiece to
cater for the different body heights of male and female microscope users worldwide. For this purpose the
ergonomic tube or ergo tube must be vertically and angle-adjustable. This enables it to be adjusted to
suit different body heights (static ergonomics) and occasionally varied by the user during extended
periods of use (dynamic ergonomics). Furthermore, the TÜV ergonomic certificate is only fully valid when
the remaining microscope workstation is ergonomically designed in terms of lighting, height-adjustable
chair and table.
A series of fundamental workplace standards, as
listed in Section 1.2 Notes on ergonomics of the
microscope, serve as a basis for this TÜV
ergonomic certificate. The TÜV certificate
(Fig. 3-32) is located on the comfort ergo tube of
the special ergonomically certified configuration.
Details of this certificate can be found online at:

upon entering ID:0000025994.
Besides this Axio Lab.A1 configuration explicitly
distinguished with the TÜV ergonomic certificate it
is also possible to enhance the ergonomic
friendliness of the microscope workstation in
stages by selecting an adjustable ergo tube or
special ergonomically designed table with fixed
stage drive.
3.5.3
Ergonomic configuration of the microscope workstation
In addition to the use of an ergonomically designed microscope, e.g. the Axio Lab.A1, the microscope
workstation must exhibit further ergonomically relevant aspects in terms of lighting conditions, air
temperature, humidity, general workplace configuration, height-adjustable chair and table surface. These
aspects are described in more detail in the following; references to standards with additional information
in square brackets. It is recommended that the Axio Lab.A1 be used in a sitting position.
Lighting requirements are determined by the visual comfort and acuity of the user. Visual comfort gives
the user a feeling of well-being, thus contributing to a high level of productivity. Visual acuity enables the
user to perform visual tasks even under difficult conditions over extended periods of time. Specifically,
this means that the workstation should not be in direct sunlight or reflected light from other sources. For
fluorescence microscopy the workstation must be capable of darkening [EN 58959, 1997] with an
illumination level of less than 50 lux [EN 12464-1].
Air temperature, humidity, air speed and ambient radiation temperature are variables which influence the
heat exchange of the human body with the surroundings. Well-being, health and efficiency of the user
can only be guaranteed if the above variables remain within a certain range. Target values are, e.g. a
room temperature of 20 °C and relative humidity of approx. 60 % [DIN 33403-2].
