GETTING STARTED

SELECTING THE CORRECT CUTTER BLADE

The cutter blade is selected based on the substrate type, coating thickness,
and the test method being used, see table below.

(Soft Substrates)
0-50|  0 – 2| 11 x 1mm| |
50 – 125| 2 – 5| 6 x 2mm| –| –
0-60|  –| –| 6 x 1mm| 6 x 2mm
61 – 120| –| –| 6 x 2mm| 6 x 2mm
121 – 250| –| –| 6 x 3mm| 6 x 3mm

FITTING THE CROSS HATCH CUTTER BLADE

The Elcometer 107 is supplied with a cutter blade. Different sizes of cutting
blades are available, see Section 6.1 ‘Cross Hatch Cutter Blades’ on page
en-8, all of which fit the adhesion tester.

To fit a cutter:

1. Use the hexagonal wrench supplied to remove the cutter securing screw by turning anti-clockwise.
2. Remove the existing cutter (if fitted) and position the new cutter.
3. Re-position and tighten the cutter securing screw.

 CHANGING THE CUTTING EDGE

Each cross hatch cutter blade has a total of 4 cutting edges, labeled 1 to 4.
When a cutting edge becomes worn, simply rotate the cutting blade by 180° to
use the next cutting edge on that side. Repeat until both cutting edges are
worn.
Remove the cutting blade, turn over, and re-fit (see Section 3.2), to use the
cutting edges on the other side.

Note: The ISO/JIS Standard recommends that the cutting tool is replaced
when the top of the blades has flattened to 0.1mm.

TEST PROCEDURE

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

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.

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. 4 If the substrate is wood or similar, make 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 backward along the diagonals of the lattice, to remove debris.
   A brush is supplied as standard with the Elcometer 07 Full Kit and can also be
   1 purchased as an optional accessory, see Section ‘Miscellaneous Spares & 6.3
   Accessories’ on page en-9.

5. Inspect the sample to ensure that the cuts have penetrated all the way through the coating.
   TEST PROCEDURE (continued)
   If the substrate is soft, jump to Step 10. If the substrate is hard or wood,
   proceed to Step 6.

6. Remove and discard two complete turns of adhesive tape. Remove an additional length of tape at a steady rate and cut a piece approximately 75mm from this length.

7. Center the cut piece of tape over the lattice and smooth it into place using a finger. Rub the tape firmly using a fingernail or fingertip to ensure good adhesion between the tape and the coating.

8. Within 5 minutes of applying the tape, remove the tape by pulling in a single smooth action taking approximately 0.5 to 1 second at an angle of 60° to the surface.

9. To maintain a permanent record of the test, retain the tape by applying it to a transparent film. 7 8 60°

10. Assess the coating adhesion by viewing the lattice of cuts in good light. If agreed, use an eyeglass to aid viewing. Compare the lattice of cuts with the ISO/JIS standards table shown in Section 5 ‘Assessing the Results’ on page en-7. 4
    A magnifier is supplied as standard with the Elcometer 107 Full Kit and can
    also be purchased as an optional accessory, see Section 6.3 ‘Miscellaneous
    Spares & Accessories’ on page en-9.

Note: Consult the relevant Standard for full details of the test method.

TEST PROCEDURE (continued)

TEST PROCEDURE: ASTM

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.
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 to remove detached flakes or ribbons of coating. 4 A brush is supplied as standard with the Elcometer 107 Full Kit and can also be purchased as an optional accessory, see Section ‘Miscellaneous Spares & 6.3 Accessories’ on page en- .9
5. Inspect the sample to ensure that the cuts have penetrated all the way through the coating.
6. Remove and discard two complete turns of adhesive tape. Remove an additional length of tape at a steady rate and cut a piece approximately 75mm from this length.
7. Centre the cut piece of tape over the lattice and smooth into place using a finger. Rub the tape firmly using an eraser on the end of a pencil to ensure good adhesion between the tape and the coating.
8. Within 90 seconds (±30 seconds) of applying the tape, remove the tape by pulling in a single smooth action at an angle of 180° to the coating surface.
9. Assess the coating adhesion by viewing the lattice of cuts using an illuminated magnifier. Compare the lattice of cuts with the ASTM standards table shown in Section 5 ‘Assessing the Results’ on page en-7.

Note: Consult the relevant Standard for full details of the test method.

ASSESSING THE RESULTS

The ISO/JIS and ASTM classifications are reproduced in the table below
however, we recommend obtaining a copy of the latest version of these
Standards.
