Equivalence key range

Example for calculating the equivalence key range (1), see the lamp
configuration sticker:
If the equivalence key of the lamp with which the device has been equipped
during the type approval is
the equivalence key range with which the device should be marked is calcu-
lated as follows:
Bottom value of the X section:
Bottom value of the Y section:
Top value of the Y section:
X is rounded up to the next whole value, Y will be rounded to the first decimal
place after the point. The equivalence key range for fluorescent lamps is then:
7.3.1 Description of the equivalence keys for UV
fluorescent lamps
The equivalence key for UV fluorescent lamps for tanning that is represented
in detail in the IEC 61228 and that is marked on the lamp in a readable and
permanent manner, is described in the following.
The equivalence key has the following structure:
Wattage – Reflector type key – UV key.
The following reflector type key should be used for the equivalence key:
O with lamps without reflector;
B with lamps that have a wide reflecting angle
N with lamps that have a narrow reflecting angle
R with lamps that have the usual reflecting angle
The following UV key should be used for the equivalence key:
UV key = X/Y;
X = the entire effective erythematic UV radiation strength across the range
250 nm to 400 nm;
Y = the relationship of the non-melanoma skin cancer effective UV radiation
strength  320 nm and > 320 nm.
X is specified in mW/m² and rounded up to the next whole value, Y will be
rounded to the first decimal place after the point. The effective values apply
100–R–47/3.2,
0.75 x 47 = 35.25
0.85 x 3.2 = 2.72
1.15 x 3.2 = 3.68
100–R–(35-47)/(2.7-3.7)
