Tensile-impact strength

The tensile-impact strength is a tensile test with a relatively high deformation rate. It is well known that materials sometimes behave brittle under dynamic loads, whereas they can appear plastic and deformable in the quasi-static, classical tensile test. This can lead to unpredictable breakage of packaging materials and technical products, e.g. under impact and drop stress.

Test Method Group: Mechanical properties

Norms:
  • DIN EN ISO 8256 (based on) (2024-03) Plastics - Determination tensile-impact strength
  • DIN EN ISO 8256 (Appendix A) (2024-03) Plastics - Determination tensile-impact strength

Required Sample Amount: testung of plane film material: sample over total width of material, min length: 0,5 m; testing of welded seams: min 30 cm of the sealed material

Standard Tests

tensile-impact strength- testing of films and sheets

Specific Norm: DIN EN ISO 8256 (Anhang A)

E.g. suitable for testing and comparing thermoforming films and sheets such as PVC, PET and PS- materials for the performance of impact resistant compounds.

tensile-impact strength- testing of welded seams/ sealings

Specific Norm: DIN EN ISO 8256 (in Anlehnung)

Testing of sealed seams on pouches, bags and sacks that are dynamically stressed during use, e.g. when handled in packaging lines by robots, during transport and use by the end customer. Especially suitable for comparative testing of materials for benchmarking and failure analysis. Not suitable for rigid films.
