# DSHR - Drying Shrinkage Test

Specify the % water content. This is normally based on plastic length, thus to calculate:

( plastic size - dry size ) / plastic size * 100

It is easiest to make bars with a 100mm mark. Then the shrinkage is just 100 minus the dry measurement.

For a comprehensive test to measure shrinkage and porosity, see the SHAB test.
