– guidance
Floors should be wood, concrete,
or ceramic tile. If floors are
covered with synthetic material,
the relative humidity should be at
least 30%.
Mains power quality should be
that of a typical low-voltage
power supply network that
supplies hospitals or buildings
used for commercial or domestic
purposes.
