  • Description

Standard: ASTM C 900, BS 1881-207

Pull-Out Tester, Digital

A Digital Pull-Out Tester is used to evaluate the pull-out strength of materials such as concrete, anchors, bolts, and fasteners. It operates by inserting a probe or anchor into the material, applying tension gradually until failure occurs, and measuring the maximum force digitally. This data is then analyzed to determine the material's fitness for construction, ensuring structures meet safety standards. Digital Pull-Out Testers offer advantages such as accuracy, repeatability, and digital data recording capabilities, enabling thorough analysis and documentation of test results for quality control purposes. The Pull Out Test Apparatus is available in a variety of capacities and sizes of wedges & adapters for selection. Specimen wedges are sold separately and users have to select the desired size (refer to Optional Accessories). 

Features of Digital Pull-Out Tester

  • Data Acquisition features advanced data acquisition systems that capture and record force data in real-time. This data can be analyzed to assess material performance and ensure compliance with industry standards.

  • Graphical Display Interface, allowing users to visualize force-time curves and other test parameters directly on the device.

  • Compact and Portable Design is a key feature of digital pull-out testers, allowing them to be easily transported to various job sites. Compact designs and lightweight construction make them convenient for field use.

  • Adjustable Test Parameters such as test speed, hold time, and maximum force limits to suit specific testing requirements and standards.

  • Compatibility with Computer Software: Many digital pull-out testers can interface with computer software for further analysis and reporting. This feature enables users to generate detailed test reports and conduct in-depth analysis of test data.

Standard: ASTM C 900, BS 1881-207

  •  ASTM C 900

ASTM C900 is a standard specification established by the American Society for Testing and Materials (ASTM) that outlines the procedure for determining the pullout strength of hardened concrete. This standard provides guidelines for conducting pullout tests, which involve applying tensile forces to a hardened concrete sample to determine its resistance to pulling out or breaking under load. Pullout strength is an essential parameter in assessing the quality and structural integrity of concrete elements in construction projects,  such as anchors, dowels, and reinforcement bars. Compliance with ASTM C900 ensures standardized testing procedures and accurate measurement of concrete pullout strength.

  •   BS 1881-207

This British Standard focuses on testing concrete structures, particularly regarding the pullout resistance of embedded reinforcing steel bars or other items within concrete. This standard provides detailed procedures for conducting pullout tests, which involve applying tension to an embedded element in a concrete sample to measure its bond strength. These tests are crucial for evaluating the connection between concrete and reinforcement, ensuring the structural integrity and safety of concrete structures. Adhering to BS 1881-207 guarantees that pullout tests are performed using standardized methods, enabling accurate and reliable assessments of concrete bond strength in construction projects.

Test Procedure of Digital Pull-Out Tester

  1. Prepare the Surface: Clean and prep the concrete surface where the test will be conducted.

  2. Insert Anchor or Probe: Place the anchor or probe into the concrete at the specified depth.

  3. Set Up the Tester: Follow the manufacturer's instructions to set up the digital pull-out tester, ensuring it's calibrated correctly.

  4. Apply Tension: Activate the tester to gradually apply tension to the anchor or probe, monitoring the force displayed on the digital screen.

  5. Record Data: Note the maximum force applied before the anchor or probe fails to hold.

  6. Analyse Results: Compare the recorded force with standards to assess the concrete's strength and integrity.

  7. Document the Test: Keep a record of the test procedure, including details like test conditions and results.

  8. Ensure Safety: Maintain safety measures throughout the test to prevent accidents.

  9. Clean Up: Clean the tester and testing area according to manufacturer guidelines for future use.
