These show the comparison between the RH predictions achieved via the one-parameter models based on RH (Eq.(1)), the one-parameter model based on vapour pressure (Eq.(6)) and the effective capacitance model including the HIR-value (Eq.(7)): top left: corrugated cardboard WP821 with CLAMls design (s = 4.6E-3); top-right: non-corrugated JPP1 cardboard with 2-P design and with sealed slits using self-adhesive tape (s = 2.5E-3); bottom-left: cardboard with textile lining (Solander box), made with LINECO glue (s = 2.5E-4); bottom-right: JPP1 cardboard coated with Moistop (s = 5.7E-5). Note that the results of the one-parameter model based on vapor pressure and the effective capacitance (HIR) model overlap significantly.
