English 6.3 Cross-Cut Adhesion according to DIN EN ISO and ASTM
In the revolver head optional cutting tools for cross-
cut can be inserted. The cutters are mounted as
described in chapter 5.2.
Important ! The sharp tip is facing toward the cutting
direction, the tool‘s sharp tip is used for the cut.
Evaluation is performed according to the standard
ranges in DIN ISO or ASTM.
Standards:
ASTM D 3002, D 3359, DIN EN ISO 2409
The standards prescribe the following spaces
between two cuts:
Film Thickness Cutter Spacing
0-60 µm 1 mm
60-120 µm 2 mm
> 120 µm 3 mm
The byko-cut is capable of work with 1mm, 1.5 mm
and 2mm cutters.
The 3mm cutting tool is too wide and does not fit
into the revolver head.
