The DeFelsko ATA50T-B PosiTest AT-A Automatic Pull-off Adhesion Tester with 50mm C1583 Kit measures the force required to pull a specified test area of coating away from a substrate using hydraulic pressure. An electronically controlled hydraulic pump automatically applies smooth and continuous pull-off pressure. The pump greatly reduces user effort and the risk of influencing the pulling process.

The AT-A's built-in rechargeable battery performs over 200 tests per charge. The supplied AC adapter / charger allows you to continue testing with AC power while the battery recharges.

The DeFelsko Positest AT-A features an environmentally sealed enclosure. It is weatherproof, dustproof and shockproof. Meeting or exceeding IP65 rating.

View test parameters and reading results. Reading is recorded as pass or fail based on set test parameters. The pass/fail results can be revised.
Notes can be added for each reading.
Include a note for a batch (group) of readings.
Record the nature of failure - cohesive, adhesive and glue failures.

Recording the Nature of the Fracture

Upon completion of a pull-off test, the dolly and coated surface should be examined. In addition to pull-off force, many National and International standards such as ASTM D4541 and ISO 4624 require the nature of the fracture to be recorded.

  • Cohesive fracture: fracture occurs within a coating layer (same coating on dolly face and coated surface).
  • Adhesive fracture: fracture occurs at the interface between layers (coating on dolly face differs from surface).
  • Glue failure: visible separation of the glue from itself, the coating or dolly (no coating visible on the dolly face).

The cohesive and adhesive fracture visual analysis can be recorded using the PosiTest AT-A's keypad or touch screen display. Alternatively, the information can be reported using the PosiTector App.

Fractures are visually estimated and recorded as a percent of each. The two layer example below illustrates a cohesive fracture within coating layer 1 and layer 2 (visually estimated at 50% each). Recorded results are included in reports.

The PosiTest AT-A can record fracture information for up to five layers. For full details and examples see Visual Analysis and Recording of Test Results.
