A range 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: 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.
