Information about tests 
Puncture resistance, quasi-statical (temperature range - 40 up to + 120 °C)
Test performed with Zwick, tensile, compression tester, testing speed 25 resp. 100 mm/min. Tests carried out at room temperature for the standard price. For tests in the thermal chamber additional charge. The minimum and maximum technically feasible temperature ranges are dependent on the material. We will gladly advise you.  
Standardprüfungen  
penetration Test ASTM F 1306 
Test probe spherical, radius = 1,6 mm, vtest=25 mm/min. This test is particularly suitable for simulating the influences of coarse grain filling goods such as pasta, rice, granules. Norm:  ASTM F 1306
Create new test penetration Test DIN EN 14477 
stylus: Diameter = 0,8 mm, spherical radius = 0,4 mm, vtest= 100 mm/min. This test  is often used to simulate damages caused by sharp or pointed filling goods, such as ground coffee, nails or damages made by birds and rodents. Norm:  DIN EN 14477
