The DWT100-42 Drop Weight Tear Tester from Imatek

Imatek manufacture arange of drop weight impact testers for measuring the fracture characteristics and fracture ductility of steel specimens according to the following standards: API recommended practice 5L3, EN 10274, ASTM-E 436 and ‘Pellini’

Key features of the drop weight tear tester range include:

  • Very robust construction stands up to the rigours of high energy testing to provide high reliability with a minimum of downtime.
  • Easily interchangeable contact parts simplify maintenance and reduce cost of ownership.
  • State-of-the-art testing accommodates impact energies up to 100,000J and specimens up to 50mm thick.
  • Very high levels of safety employing multiply redundant systems, compliant with 89/392/EEC and 91/368/EEC machinery safety directives.
  • Automated specimen loading provides compliance with cycle times required by test methods, while maintaining operator safety.
  • Very rigid base and anvils ensures very low flexure under high test loads.
  • Guided mass system to ensure that the impact geometry is correct throughout the entire test.
  • Highly accurate and repeatable drop parameters.
  • High quality, easy to use control software ensures consistency and enhances throughput.
  • Ergonomically designed, no requirement for the operator to work at elevated heights or handle excessive physical loads.
  • Optional instrumentation package to measure impact force up to 1500kN. Provides values for peak force and energy to fail, together with a high resolution force-deflection curve to analyse failure mode.
  • Optional variable mass system to provide precise control over impact parameters.
  • Optional high speed, fully integrated video system to provide visualization of specimen failure mode.
  • Optional liquid cooled temperature conditioning bath.
  • Responsive life-time technical support.

The DWT100-42 drop weight tear trester from Imatek features impact energy up to 103,000J requiring a floor-to-ceiling height of 7.5m (1000kg to 2500kg impact mass at 4.5m/s to 9.0m/s impact velocity)
