to expansion or contraction may be more severe than those arising from increased thermal conductivity of the foam. Since it is impossible to duplicate all exposure conditions, durability tests are usually conducted for brief periods under more severe conditions, often on the assumption that the greater severity of the test constitutes acceleration of any detrimental processes. This assumption should not be generally made, since the volume changes induced in the test would probably not be… CONTINUE READING
