Linear dimensional changes/dimensional stability/temperature stability of films and sheets

Determination of linear dimensional changes after exposure to temperature (till ca. 175°C, depending on material) of plastic films and sheets. Please select test temperature. We recommend the examination of shrinkage or shrinking stress for shrink films.

Test Method Group: Mechanical properties

Norms:

DIN EN ISO 11501 (2004-10) Plastics – Film and sheeting – Determination of dimensional change on heating
DIN 53377 (2015-04) Testing of plastic films – Determination of dimensional stability
ASTM D 1204 (2014) Standard Test Method for Linear Dimensional Changes of Nonrigid Thermoplastic Sheeting or Film at Elevated Temperature

Required Sample Amount: Approx. 1 m² or 15 DIN A 4 sheets, minimum sample width 250 mm; preferably samples over the complete material width, e. g. approx. 1 linear metre of 1 m width
