4 PERFORMING THE TEST (continued)
When using the Elcometer 506 Digital Adhesion Tester or Elcometer
510 Automatic Adhesion Tester with 50mm dolly adaptor, the dolly size
should be set to 20mm before test - refer to the Elcometer 506 or 510
User Guide for instructions on how to select the 20mm dolly size.
ELCOMETER 106 SCALE 6 DOLLY ADAPTOR
(Part Number: T99923938)
When testing the Elcometer 106 Pull-Off Adhesion Tester with the
Scale 6 dolly adaptor, the Elcometer AVU reading should be multiplied
by a conversion factor of 6.4516 before comparing with the adhesion
gauge reading.
For other manufacturers' gauges, please refer to the manufacturers'
instructions for adhesion readings using 20mm dollies.
5 ASSESSING THE RESULTS
Adhesion gauges should be tested at a number of pressure / adhesion
values across their measurement range - see Appendix A page en-8
for recommended test pressures for Elcometer pull-off adhesion
gauges.
When comparing the adhesion gauge reading with the Elcometer AVU
reading, the user should refer to the adhesion gauge's accuracy
statement. This is usually quoted in the operating instructions or
technical data sheet.
The adhesion gauge can be stated as performing within specification if
the Elcometer AVU adhesion reading is within the stated accuracy of
the adhesion gauge. If outside specification, re-calibration is
recommended - contact Elcometer or your local supplier for further
information.
The Elcometer AVU can be used to re-certify adhesion gauges if it has
a current and valid calibration certificate, dated within 12 months of
test. This provides users with a Calibration Certificate which is
traceable through the certification of the Elcometer AVU unit in
accordance with Elcometer's procedures.
The Elcometer AVU is supplied with a Test Certificate as standard and
is also available with an optional Calibration Certificate. To certify or
re-certify the Elcometer AVU, contact Elcometer or your local supplier.
