dimensional stability

[də·′men·chən·əl stə′bil·əd·ē]
(graphic arts)
The percentage of change in size of paper under two different conditions of temperature and humidity.
(materials)
The ability of a material, such as a textile or plastic, to hold its shape over a period of time and under specific conditions.

Dimensional stability

Applies to a material that has little moisture movement and creep, since thermal and elastic deformation are unavoidable.

dimensional stability

The degree to which a material maintains its original dimensions when subjected to changes in temperature and humidity. See equilibrium moisture content.
