DY-2 Family Pull-Off Testing

The Proceq™ 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.

Conforms to: EN 1542, EN 1015, EN 1348, ISO 4624, BS 1881 Part 207, ASTM D4541, ASTM C1583, ASTM D7234, ASTM D7522, ZTV-SIB 90. Additionally, most standards state an accuracy requirement. The DY-2 is calibrated according to EN ISO 7500-1 Class 1 and thereby exceeds the accuracy requirements specified in any of the standards listed above.

Pull-off testing is one of the most widely used test methods in the construction industry. It is indispensable for the diagnosis of structural damage to buildings as well as for checking complete renovation work.

Complete range of applications covered
The three models of the DY-2 Family differentiate by a maximum pulling force. While DY-216 (15.5 kN, 3485 lbf) is covering most applications, DY-206 (6 kN, 1349 lbf) has an increased accuracy for low strength applications such as testing adhesive strength of mortars and renders. DY-225 (25 kN, 5620 lbf) can be used 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.

DY-2

Constant load rate
One of the major influences on the result of a pull-off test is the operator influence in the application of a constant load rate. The newly introduced DY-2 models with their integrated, feedback controlled motors remove this variable completely, by providing a fully automated test at a constant load rate which can be verified.

Unique in parameter setting
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 as well as the 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.

Application Range

top
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):

Technical Data
  Tensile Force
Test Disc Ø 50mm
DY-206: 0.6 - 6 kN 0.3 - 3.1 MPa
135 - 1349 lbf 44 - 443 psi
DY-216: 1.6 - 15.5 kN 0.81 - 7.8 MPa
360 - 3485 lbf 118 - 1145 psi
DY-225: 2.5 - 25 kN 1.3 - 12.7 MPa
562 - 5620 lbf 185 - 1847 psi

DY-206 has increased accuracy for low strength applications such as testing adhesive strength of
mortars and renders. DY-216 covering most applications. 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.

 

Failure Mode Reporting

top
Most pull-off testing standards require the operator to record the mode of failure. DY-2 is unique in that it allows this information to be saved along with the test result.

Failure Example For example "B 100%" indicates a complete failure in the overlay or repair material.

 

Complete Report of Load Rate: DY-Link Software

top
DY-2 provides documentary proof that the test was actually carried out with the specified load rate. The load rate curve is saved along with the test results and may be downloaded to a PC for reporting, or it may also be viewed in real time if the DY-2 is connected to a PC during the test.
