Standard Test Methods for Strength Properties of Prefabricated Architectural Acoustical Tile or Lay-In Ceiling Panels

Importancia y uso:

4.1 Knowledge of hardness is useful in the development and the quality control of acoustical tile and lay-in ceiling panels. Deviation from an established hardness range will assist in pointing out processing errors or defective raw materials, thereby aiding the maintenance of uniform product quality.

4.2 This property is also useful in comparing the relative abilities of materials to resist indentations on the panel surface caused by impacts.

4.3 Since the hardness varies with the thickness, only samples of the same thickness shall be directly compared.
