Proceq Launches New DY-2 Fully-Automated Pull-Off Tester

Schwerzenbach/Switzerland, February 2013 – With the launch of the DY-2 Family, Proceq introduces new automated pull-off testers which cover the complete range of pull-off applications. DY-2 has an  integrated, feedback controlled motor which guarantees a constant load rate. The unique features offer a complete record of the pull-off test, proving that the test was carried out in accordance with the  applicable standard. All models are calibrated according to EN ISO 7500-1 Class 1 and thereby exceed the accuracy requirements specified in all major standards.

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.

Today, Proceq announces an expansion to its existing Dyna pull-off tester portfolio with the DY-2 Family (DY- 206, DY-216 and DY-225), a new generation of automated pull-off tester.

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, 3485lbf) 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.

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.

Wide range of applicable standards

DY-2 conforms to all of the following standards: 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.
