    4 PREPARING FOR A TEST 4.1 Attaching the pull stub to the coating These instructions describe the use of Araldite epoxy resin to attach the pull stub to the coating. Use of other adhesives may require different surface preparations and/or application techniques. Please refer to the relevant manufacturers recommended procedures.

    4.4 Preparing the piston 1. Rotate the Rate control on the front panel of the control module to 0.005. Note: The closed position is 0.000. Do not overtighten the Rate control as this may damage the valve inside the control module. 2.

  • Page 16: Pull Off Test Procedure

    5 PULL OFF TEST PROCEDURE Before you start a test, the adhesive between the pull stub and the coating must be cured. Prepare the instrument and piston - see “Preparing for a test” on page 9. 5.1 Pull off test If the adhesion need only be tested to a specified pull off tensile strength (POTS), the pressure must be determined by the burst pressure (BP) to POTS Conversion Table - see “Piston burst pressure to POTS conversion”...

The digital piston pressure gauge should read 00.0. If not, adjust the zero setting by holding in Reset and at the same time turning the Zero reset control on the back panel of the control module.

  • Page 18: After The Test

    5.2 After the test It is safe to leave the system pressurised between pull off tests. However, if the instrument is to be transported, or left unused for a long period of time, it is advisable to shut down (depressurise) the system. 1.
