Specifies a method for determining the water absorption of rigid cellular plastics by measuring the change in buoyant force resulting from immersion in distilled water.

Scope

This Method sets out a method for determining the water absorption of rigid cellular plastics by measuring the change in buoyant force resulting from immersion in distilled water.
NOTES:
1 Some materials may absorb significant additional amounts of water when immersed for longer than 96 h, or under a greater hydrostatic head.
2 If a full assessment of the water absorption characteristics of a rigid cellular plastics is required, it is essential to make measurements over a range of immersion periods and plot a graph of water absorption against time.
