A single column system can be used with a webcam connected to Bluehill Universal to track the force needed to tear flexible plastic film in accordance with ASTM D1004-13.
To determine tensile and elongation properties of microtensile plastics in accordance with ASTM D1708-13, use a 3345 system with a 225 lb. load cell.
ASTM D3163 is a standard to evaluate the shear strength of adhesively bonded rigid plastic lap shear joints without damaging the bonds.
With thin plastic sheeting, grips need to prevent slippage without prematurely tearing the specimen in tensile testing in accordance with ASTM D882.
Tensile testing of catheter tubing with pneumatic cord and yarn grips determines the breaking strength for quality control. Tortuosity testing of catheter tubing enables researchers to quantify the frictional forces during insertion and removal of medical tubing.
For thermal insulating materials used in construction, EN 1607 tells how to determine the tensile strength perpendicular to its faces.
Following ISO 11897 to determine tear propagation of thin films using Instron pneumatic side acting grips with rubber coated faces.
Flexible cellular polymeric materials can be pulled apart to find out the load and strain to determine the strength and elongation at break.
The strength and deformation characteristics of rigid cellular plastics can be determined with tensile testing to find the change in length.
When measuring modulus and strain of plastics, use an extensometer that provides high accuracy and has an acceptable gauge length and travel.
Video extensometry and pneumatic grips with rubber faces the same width of the specimen should be used in tensile testing of delicate plastic films and sheets.
ISO 8067 gives guidelines for analyzing the peak force and tear strength of flexible cellular polymeric materials with a particular thickness.
For testing polymer hydrogels, use an electromechanical test system with a low force load cell, pneumatic or manual screw action grips, and a BioPuls™ Bath for realistic testing conditions.
