TQCSheen Adezyon Pull Off Test Cihazı - Manual

Positest Adhesion Tester - Manual 
The new PosiTest Adhesion Tester measures adhesion
substrates. There is a manual and an automatic model

Both models have a hydraulic pump. The pump of the
automatic version is electronically controlled and
applies smooth and continuous pull-off pressure. This
greatly reduces user effort and the risk of influencing the pulling process.
Self-aligning aluminum dollies enable
accurate measurements on smooth or uneven surfaces
The internal memory of the Manual version stores maximum pull-off pressure,
dolly size for up to 200 pulls. The automatic version stores maximum pull-off
pressure, rate of pull, test duration, dolly size, pass/fail,nature of fracture and
user notes for 100,000 pulls in up to 1,000 batches in itsinternal memory and pull rate,
pull limit and hold time are user-adjustable with the impact and scratch resistant color
touch screen with keypad for operation with or without gloves.
Every PosiTest Adhesion Tester pressure system is calibrated and certified to ± 1%
accuracy using a NIST traceable load cel. Evaluating measured values on PC is possible
by using an adapter and PC-software.


Conforms to international standards including ASTM D4541/D7234, ISO 4624/16276-1,
AS/NZS 1580.408.5 and others. Look up the appropriate standard for a correct
execution of the test.

With this method, a loading fixture commonly called a dolly or stud supplied as
smooth steel or aluminium must be cleaned before it is glued with epoxy or acrylic
adhesives to the surface. The coating surface must also be cleaned. Roughen the
bonding surface of the dolly either with sandpaper or light abrasive blasting. The
adhesive must cure for the amount of time recommended by the manufacturer.
This can be several hours to a day, depending on the adhesive and the temperature.
A critical step in the test procedure is positioning the dolly onto the surface. Avoid any
movement, especially twisting, that can result in stress discontinuities during the pull testing.
Wipe away any excess adhesive with a cotton swab once the dolly is in place. Place the self
aligning adapter over the dolly by lifting the quick coupling ring upwards and when in place to
release it. The pull is perpendicular to the surface, so tensile strength is being measured.
The manual AT load to the dolly should be increased continuously and smoothly at a rate
not to exceed 1 MPa/s (145 psi/s). In case of the automatic AT-A this is done by continued
build up provided by the unit. Keep applying the load until failure occurs
(or until the maximum force has been applied).


• Though robust in design, this instrument is precision-machined. Never drop it or knock it over
• Always clean the instrument after use.
• Clean the instrument using a soft dry cloth. Never clean the instrument by any mechanical
  means such as a wire brush or abrasive paper. This may cause, just like the use of aggressive
  cleaning agents, permanent damage.
• Do not use compressed air to clean the instrument.
• Always keep the instrument in its case when not in use.
• We recommend annual calibration


• Not suitable to be put in the sun or in the high light
• Avoid using it in over-high or over-low temperature environment
• Avoid humidity
