Using The Coating Calibration Mould - Elcometer 500 User Manual

11 USING THE COATING CALIBRATION MOULD

In addition to measuring coatings on concrete and other similar
substrates (see Section 7.5 'Measurement Substrates' on page en-12),
the Elcometer 500 C1 and C2 coating thickness probes have been
designed to measure coatings on the steel Elcometer 500 Coating
Calibration mould (CCM) for calibration purposes.
Available to purchase as an optional
accessory, the Elcometer 500 Coating
Calibration Mould (CCM) is a steel mould
with two chambers - a sample chamber and
overflow chamber - which can be used to
determine the sound-velocity of coating
materials for calibration.
By using the Elcometer 500 CCM following the procedure outlined
below, the Elcometer 500 gauge calibration will be traceable to
National and International Standards.
To use the Elcometer 500 CCM:
1 Place the Elcometer 500 CCM onto a
flat, horizontal surface.
2 Completely fill the sample chamber (a)
with the test coating, making sure that
there is a slight dome or meniscus
(Figure 22).
3 Using the plastic scraper supplied (b),
scrape over the coating allowing the
excess to fall into the overflow
chamber (c) (Figure 23).
4 Allow the coating to dry, ensuring
that the Elcometer 500 CCM
remains flat at all times.
