The XJU-5.5J Izod Impact Testing Machine, also known as an Izod Pendulum Impact Tester, is engineered to evaluate the impact ductility of non-metallic specimens. It covers engineering plastics, glass fiber reinforced materials, ceramics, cast stone, plastic electrical components, reinforced nylon, and electrical insulating materials.

This instrument is widely deployed across the chemical sector, research institutions, quality inspection divisions, and specialized manufacturing enterprises. The equipment assembly consists of a rigid frame, specimen mounting base, pendulum striking head, operation assembly, and dial indicator.

A pendulum hammer with predefined energy strikes the specimen mounted on a horizontal beam and fractures the specimen via a single impact blow. The impact position is aligned centrally between the two supporting points.

The absorbed energy consumed by the specimen upon fracture is quantified by computing the discrepancy in pendulum energy before and after impact. Subsequently, the impact strength value is derived from the original cross-sectional area of the test specimen.

• Adopts high-hardness precision bearings together with a single-axis photoelectric sensor to substantially suppress frictional losses, keeping friction energy dissipation well under the thresholds specified by relevant standards.
• Delivers intelligent operational status alerts in response to real-time impact events.
• Enables continuous interaction with test operators to secure high success rates for each impact test.

The equipment complies with a full set of international and domestic testing specifications, including:

• DIN EN ISO 180
• ASTM D256
• NF T51-911
• GB/T 1843
• GB/T 2611
• Other relevant standards
