Static Electricity
At low humidities static electricity charges with high voltages may
build up, favoured by external influences (friction during material
transport, high ambient isolation value), which may not only lead to
strong fluctuations in the measured data or negative values, but
also to the destruction of electronic components in the instrument.
Even the instrument operator may - inadvertently - contribute to the
build up of a static charge by the clothing worn. A considerable
improvement can be achieved by the operator and the measuring
instrument being kept absolutely still during measuring, as well as
by earthing (contact with conducting metal, water or heating pipes,
etc.).
4.2.3
Wood Moisture Equilibrium
If wood is stored for extended periods in a given climate it assumes
a moisture content corresponding to this climate, which is also
termed equilibrium moisture or wood moisture equilibrium.
When the equilibrium moisture is reached the wood does not give
off or absorb any further moisture for constant ambient climatic
conditions.
The wood moisture equilibrium in the winter months is approx.
6.0% to 7.5% wood moisture (corresponds to 30
–40% rel. humidity
and 20-25° C) and in the summer months approx. 10.5% to 13.0%
(corresponds to 60
–70% rel. humidity and 25° C). Additional data
and tables can be found on the internet.
