Product Description
PBT-01Board Thickness Tester is used for determining the single sheet thickness of corrugated fibreboard intended for use in the manufacture of packing cases. It’s applicable to all types of corrugated fibreboard.
Principle
Measurement of thickness of corrugated board under a specific static load by means of a high-precision PBT-01Board Thickness Tester.
Description
PBT-01Board Thickness Tester has two plane, parallel, circular pressure faces, between which the corrugated board is placed for measurement.
The pressure exerted between the pressure faces during the thickness measurement shall be 20 kPa ± 0,5 kPa.
The two pressure faces form an integral part of the tester, such that one face is fixed (the anvil) and the other is movable, in a direction perpendicular to the plane of the fixed face, smoothly at a speed of 2 mm/s to 3 mm/s, one face shall be 35,7 mm + 0,3 mm in diameter and the second face shall be of such a size that it is in contact with the whole area of the other face when it reads zero. Thus, a circular region of a test piece 1000 mm²±20 mm²(10 cm²±0,2 cm²) in area, is subjected during the thickness measurement to the pressure exerted between the faces.
The instrument shall be sufficiently accurate to permit measurements to be made to the nearest 0,05 mm

FAQ
1. What is corrugated fibreboard?
Corrugated fibreboard is the board consisting of one or more sheets of fluted paper glued to a flat sheet of board or between several sheets.
2. What is single sheet thickness corrugated fibreboard”
It refers to the distance between one surface of a corrugated fibreboard and the other, measured under an applied static load.
