Electromagnetic
environment - regulations
Floors should be made of
wood or concrete or should
be covered with ceramic
tiles. If the floor is covered
with synthetic materials, the
relative humidity must be at
least 30%.
The quality of the supply
voltage should match the
typical office or hospital
environment.
The quality of the supply
voltage should match the
typical office or hospital
environment.
The quality of the supply
voltage should match the
typical office or hospital
environment.
NOTE:
U
is the a.c. supply voltage
T
before application of the test levels
Magnetic fields at mains
frequency must comply with
the typical values found in
office or hospital
environments.
