Oxidation Induction Time (OIT)
Defined as the time it takes for a sample to oxidize under an oxygen stream at a constant temperature of 200 degrees after heating under a pure nitrogen flow. This test is performed in our laboratory according to TS EN ISO 11357-1 and TS EN ISO 11357-6 standards.
 
Shore A Hardness
Shore hardness value is used to determine the hardness of polymer materials. Our laboratory measures the hardness of polymers using the TS EN ISO 868 standard.
 
Determination of Tensile Properties
This involves stretching materials at a constant speed until they break, determining values like tensile stress at yield, tensile strength, tensile stress at %x elongation, tensile stress at break, elongation at yield, elongation at break, elongation at tensile strength, and nominal elongation at break. Our laboratory uses TS EN ISO 527-1, TS EN ISO 527-2, TS EN ISO 527-3, and TS EN ISO 12311-2 standards.

An experiment to determine the behavior of a sample against bending after exposure to low temperatures. Conducted in our laboratory according to the TS EN 495-5 standard.
 
Glass Transition Temperature
A fundamental distinguishing characteristic of polymeric materials. It's the temperature limit at which the material starts losing its glassy properties and begins to gain viscous properties. Performed in our laboratory according to TS EN ISO 11357-2.
 
Static Puncture Determination (CBR)
This test measures the puncture resistance of a sample; it is done by using a universal testing machine and a flat-ended piston to determine the force required to puncture the sample. Conducted according to TS EN ISO 12236.
