Particleboards and fibreboards – Determination of swelling in thickness after immersion in water

Despite its title, the standard is applicable to Oriented Strand Board. It specifies a method of determining the swelling in thickness of flat-pressed or drum-pressed particleboards including OSB.

Swelling in thickness is determined by measuring the increase in thickness of the test piece after complete immersion in water.
