tensile test films and laminates (temperature range -40 to +120 °C)

Determination of: secant modulus, tensile strength, elongation at break (accredited test method)

Test Method Group: Mechanical properties

Norms:
  • DIN EN 29073-3 (1992-08) Textiles; Test method for nonwovens; Part 3: Determination of tensile strengh and elongation
  • DIN EN ISO 13934-1 (2013-08) Textiles - Tensile properties of fabrics - Part 1: Determination of maximum force and elongation at maximum force using the strip method
  • DIN EN ISO 527-1 (2019-12) Plastics – Determination of tensile properties – Part 1: General principles
  • DIN EN ISO 527-3 (2019-02) Plastics - Determination of tensile properties - Part 3: Text conditions for films and sheets
  • ASTM D 882 (2018-08) Standard Test Method for Tensile Properties of Thin Plastic Sheeting

Required Sample Amount: approx. 0,1- 0,2 m² or 2 DIN A 4 sheets, minimum sample width resp. width 150 mm, optimum: film samples over total material width, e.g. approx. 2 linear meters for a film width of 0.5 m
