Parameter | Definition | Method | Reference |
---|---|---|---|
Maximum water content (MWC) | The amount of water in the totally waterlogged sample as a percentage of the dry mass | Sample is weighed both waterlogged and oven dry | |
Basic density | The ratio between the waterlogged volume and the dry mass | The waterlogged volume is calculated (e.g. by displacement), then sample is weighed dry | |
Residual density | The ratio between the basic density and the average density of non-degraded wood | Basic density divided by the density for non-degraded wood of the same species | [45] |
Shrinkage | The size of the dry sample as a percentage of the size of the waterlogged sample | Sample is measured in three planes before and after drying | |
Porosity | The fraction of the volume of a sample not occupied by the cell wall material | The waterlogged volume is compared to the pore volume (measured using a gas pycnometer) |
