3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Thickness
dL
The thickness of the product under a load of 250Pa, expressed in dL.
3.2
Thickness
dF
The thickness of the product under a load of 2kPa, expressed in dF.
3.3
Thickness
dB
The thickness of the product after holding it under a load of 50kPa for a specific time, and then returning to a load of 2kPa for a specific time, expressed in dB.
4 Principle
Measure the distance between the rigid plate placed on the bottom surface of the test piece and the rigid plate that applies a specific load to the upper surface of the test piece. This distance is
The thickness of the product.
