6.4.8 Table m.n.o. 380-3000
Table m.n.o. 380-3000 shows the exposure limits for parameters “m”, “n”, “o”.
The displayed values are:
• E
skin
[W/m
2
] irradiance value (corresponding to the instant value if a single
sample is taken into consideration, and to the mean value if several samples
are taken into consideration).
• H
skin
[J/m
2
] dose value regarding the samples taken into consideration.
• Exposure time limit (t_lim) for “o” index necessary for exceeding the threshold,
calculated with the following formula:
t_lim = 35600/E
skin
if the found time is > 10s
otherwise:
t_lim = (20000/ E
skin
)

• Exposure time limit (t_lim) for indexes “m” and “n”
Limits “m” and “n” should be calculated in the 780-3000 spectral interval. Since this
spectral range is not available in the instrument, the same channel of the “o” limit is
used; in this case, values will be greater than real values and consequently they will
be in favor of worker safety.
As to exposure times greater than 1000 seconds, the “n” limit is calculated:
if E
IR
≤ 100 W/m
2
then the “n” limit is not satisfied;
if E
IR
> 100 W/m
2
then the exposure time is calculated in order to return back with-
in “n” limit, in particular:
t_lim=(18000/ E
IR

If the Include in Report box is selected, the data in the table will be included in the fi-
nal report.
