4 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 Centre the cut piece of tape over the
lattice and smooth into place using a
finger. Rub the tape firmly using a
finger nail or finger tip 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 seconds 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.
10 Assess the coating adhesion by
viewing the lattice of cuts in good light.
If agreed, use an eye glass 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.
A magnifier is supplied as standard with the Elcometer 107 Full Kit and
4
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.
