Fuel particle timelag is based on the amount of time necessary to lose or gain 63 percent of the difference between the initial moisture content and the equilibrium moisture content at a constant temperature and relative humidity. A 100-hour timelag fuel particle adjusts to changes in equilibrium moisture content on the scale of days to weeks.

 

Dead fuel particles with a diameter between one and three inches are considered to have a timelag of 100 hours (about four days).
