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)
