Definition
require greater time for the moisture to travel from the interior to the surface.
Term
Balance (specifications)
Definition
accurate, readable and sensitive to withing 0.1% of the test load at any point within the range of use.

Definition
ASTM C-566
Term
Source of Heat (specifications)
Definition
Ventilated oven capable of maintaining temperature surrounding the sample at 110+/-5C (230+/-9F), Other sources may be used, such as hot plate, heat lamps or ventilated microwave oven.
Term
Sample Container (specifications)
