Artifact or Sample #:

The three pieces of information described below are required to calculate a result.

1. Average density of normal wood.

The average density of normal wood of the same species expressed as the oven dry weight divided by the green volume.

Normal density

(g/cm³)

 

   
2. Actual density of the artifact wood
as determined by one of the following options.

Rg

(g/cm³)

 

 

µ max

(%)

 

 

Weight in water

Weight in air

3. Moisture content (MC) at fibre saturation point (FSP).

The moisture content at the fibre saturation point of normal undeteriorated wood of the same species.

MC at FSP

(%)

 

For comparison the values for moisture content at fibre saturation from Kollman and Coté are provided.
