15. ENVIRONMENT CORRECTION
Generating sets may be loaded up to their rated power only under the
rated ambient conditions. If generating set use is under conditions
which do not conform to the reference conditions as stipulated in this
part of ISO 8528, and if cooling of the engine or alternator is impaired,
e.g., as a result of operation in restricted areas, a reduction in power
is necessary.
The rated power output is based on the standard condition as follows:

Altitude
：
0m

Ambient temperature: 25
℃

Relative humidity: 30%
Factor of environment correction C:
Altitude(m)
Ambient temperature
℃
25 30 35 40 45
0 1 0.98 0.96 0.93 0.90
500 0.93 0.91 0.89 0.87 0.84
1000 0.87 0.85 0.82 0.80 0.78
2000 0.75 0.73 0.71 0.69 0.66
3000 0.64 0.62 0.60 0.58 0.56
4000 0.52 0.52 0.50 0.48 0.46
NOTE:
Relative humidity 60% correction factor C-0.01;
Relative humidity 80% correction factor C-0.02;
Relative humidity 90% correction factor C-0.03;
Relative humidity 100% correction factor C-0.04;
Example: Generator rated power P
