Appendix

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
for a distance of 25 cm and under the conditions of an optimum UV radiation
strength.
Note
One example for an equivalence key is specified below:
100 W reflector lamp with a reflector angle of 220°
erythematic UV radiation strength
(250 nm to 400 nm) = 47 mW/m²
short wave NMSC effective UV radiation strength
(≤ 320 nm) = 61 mW/m²
long wave NMSC effective UV radiation strength
(> 320 nm) = 19 mW/m²
lamp equivalence key: 100–R–47/3.2
