The Elcometer 107 can be used in accordance with ISO/JIS and
ASTM Standards. The test procedure is dependent on the standard
being used.

4.1 BEFORE YOU START

1 Select and fit the appropriate cutter blade for the test method -
see Sections 3.1 & 3.2 on page en-3.
2 Select the correct adhesive tape - see Section 6.2 on page en-9.
4.2 TEST PROCEDURE: ISO/JIS
1 Place the cutting edge on the sample.
2 Press down gently and pull the
adhesion tester towards you in one
steady movement to make a series of
parallel cuts approximately 20mm
long. Apply sufficient pressure to
ensure you cut right through the
coating to the surface of the substrate.
If the substrate is wood or similar, make
4
cuts at a 45° angle to the direction of the
grain.
3 Place the cutting edge on the sample at
a 90° angle to the first cut and repeat
Step 2 to create a lattice pattern on the
coating.
4 Brush the sample lightly several times,
forward and backwards along the
diagonals of the lattice, to remove
debris.
A brush is supplied as standard with the
4
Elcometer 07 Full Kit and can also be
purchased as an optional accessory, see
Section 6.3
Accessories' on page en-9.
5 Inspect the sample to ensure that the
cuts have penetrated all the way
through the coating.
