DY-2 Pull Off Tester
The DY-2 family of automated pull-off testers covers the complete range of pull-off applications with unmatched ease of operation and a unique capability to store a complete record of the test.
The DY-2 is further unique in that it records every single test parameter required by the specification.
- Time and date of the test
- Test disc size
- Maximum load applied
- Automatic calculation of bond strength
- Applied load rate with graphical record
- Complete time of test
- Failure mode
For the very first time, the operator is able to provide a complete record of the pull-off test, proving that the test was carried out in accordance with the applicable standard.
Three versions of DY-2 are available differentiated by maximum pulling force. This covers the complete range of pull-off applications (examples for Ø 50mm test discs) for normal, low strength such as mortar or high strength such as carbon fibre reinforced polymer.
DY – 2 Models
| Model | Working Range* | Description | |
| Tensile Force | Pressure (Test Disk Ø 50 mm) | ||
| DY-206 | 0.6 - 6 kN | 0.3 - 3.1 MPa | DY-206 has increased accuracy for low strength applications such as testing adhesive strength of mortars and renders. |
| DY-216 | 1.6 - 15.5 kN | 0.81 - 7.8 MPa | DY-216 covering most applications. |
| DY-225 | 2.5 - 25 kN | 1.3 - 12.7 MPa | DY-225 for very high strength applications such as testing of fibre reinforced polymers bonded to concrete structures or testing the bond strength of repair and overlay materials. |
Features
- Integrated, feedback controlled motor removes operator variations by fully automated testing at a constant load rate which can be verified.
- Full data logging including failure mode entry options for up to
- Automatic calculation of strength for different test discs without re-calibration of system
- DY-Link software displays a complete record of test including load rate graph
- Wide range of test disks/dollies
Applications
- Concrete or shotcrete tensile strength measurement
- Measuring the bond of overlays, renders or repairs
- Coating adhesion
- Pull off testing is also used for exotic testing applications such as testing the integrity of laminated carbon brake disks
Benefits
- Failure mode reporting – The DY-2 is unique in allowing the operator to record the location of the break during a test in the same record as the strength measurement.
- Six months mechanical and 2-year electronic component warranty
- DY-2 is calibrated to EN ISO 7500-1 Class 1, this calibration exceeds the accuracy requirements of all standards stated later in this brochure
