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:
y
100 W reflector lamp with a reflector angle of 220°
y
erythematic UV radiation strength
(250 nm to 400 nm) = 47 mW/m²
y
short wave NMSC effective UV radiation strength
(
≤
320 nm) = 61 mW/m²
y
long wave NMSC effective UV radiation strength
(> 320 nm) = 19 mW/m²
y
lamp equivalence key: 100–R–47/3.2
