8.1 Convex surfaces
For convex surfaces plesae use the following items:
Samples
∅
≥
8mm:
rubber gasket B
Samples
∅
≥
6mm:
rubber gasket
∅
1,5mm and C mask or
rubber gasket
∅
1,5mm and D mask
Samples
∅
< 6mm:
under certain circumstances measureable with the electrolyte
cup
Samples
∅
≥
4mm:
rubber gasket
∅
1,5m (can be adapted to the diameter
of sample) in combination with the C or D mask
Use abrasive paper to adapt the circular gasket to the shape
of sample.
Samples
∅
< 4mm (e.g. wires):
electrolyte cup
Wires
∅
≥
2 mm:
electrolyte cup and mask
The rubber gasket B should not be adapted to the
diameter of sample as this would change its defined
measuring area.
Wires
∅
≤
0,3mm:
depending on the type and thickness of coating measureable
in the electrolyte cup
Adapting the rubber gasket to the shape of sample:
Rubber gasket
1,5 mm dia.
gasket edges
rounded with
abrasive paper
Bottom side of rubber gasket
Longitudinal section of rubber gasket
