6 PERFORMING THE TEST (continued)
6.2 USING 14.2mm DOLLIES - ANALOGUE PRESSURE GAUGE
Follow the procedure outlined in Section 6.1 then multiply the 20mm scale pressure reading by 2.
10MPa on 20mm Scale = 20MPa for a 14.2mm dolly
1000psi on 20mm Scale = 2000psi for a 14.2mm dolly
6.3 USING 14.2mm, 20mm OR 50mm DOLLIES - DIGITAL PRESSURE
GAUGE
1 Select the measurement units; MPA or PSI, see Section 9.3
2 Select the dolly size, see Section 9.4
3 Hold the gauge steady with one hand and turn the crank handle
clockwise slowly and evenly to apply an increasing force to the
dolly and hence stress to the coating
Note: The rate at which the force is applied (the speed of rotation of the crank
handle) should be in accordance with the relevant Standard.
Continue until either;
(a) the coating fails and the dolly is removed from the surface
(destructive testing) or;
(b) the minimum specified pressure value is reached
(non-destructive testing)
4 Record the pressure indicated on the display (a) and unwind the crank handle and coarse
adjustment screw
Do not exceed the maximum pressure as overloading could damage the gauge.
Note: Dollies can be reused after cleaning until either the top of the dolly where it is held in position by the quick connect
coupling is severely deformed or the dolly surface is no longer flat. Additional dollies are available from Elcometer or
your local supplier - see Section 10 on page 12 for details.
