7.3 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
100–R–47/3.2,
the equivalence key range with which the device should be marked is calcu-
lated as follows:
Bottom value of the X section: 0.75 x 47 = 35.25
Bottom value of the Y section: 0.85 x 3.2 = 2.72
Top value of the Y section: 1.15 x 3.2 = 3.68
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:
100–R–(35-47)/(2.7-3.7)
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 α > 230°;
N with lamps that have a narrow reflecting angle α < 200°;
R with lamps that have the usual reflecting angle 200° ≤ α ≤ 230°.
