Plastic Tensile Strength Test

A universal testing machine tensile testing machine is needed to perform this test.

Plastic tensile strength test. The tensile testing machine pulls the sample from both ends and measures the force required to pull the specimen apart and how much the sample stretches before breaking. One of the most common specifications that our customers follow is astm d882 which is the standard test method for tensile properties of thin plastic sheeting. The specimens loaded on the machines are set as per astm din iso tensile test specimen dimensions. Astm d638 is the most common testing standard for determining the tensile properties of reinforced and non reinforced plastics.

The figure below from quadrant engineering plastic products shows the test geometry. For this test plastic samples are either machined from stock shapes or injection molded. This includes astm d638 technically equivalent to iso 527 1 is a testing standard which ascertains the tensile properties of a plastic material. The test is conducted at tensile rates ranging from 1 to 500 mm min until the specimen fails yields or breaks.

Plastic tensile test instruments universal test machines provide a constant rate of extension because plastic tensile test behavior is dependent on the speed of the test machine. Astm d638 is one of the most common plastic strength specifications and covers the tensile properties of unreinforced and reinforced plastics. A tensile test is typically governed via standards and the two most common in the plastics industry are astm d638 and iso 527. Tensile testing is performed on a variety of materials including metals plastics elastomers paper composites rubbers fabrics adhesives films etc.

The test method can be used for testing materials up to 14mm 0 55 in and the material should be in the shape of a dumbbell or dog bone. This test method uses standard dumbell or dogbone shaped specimens under 14mm of thickness. The most common way to measure the yield strength of plastics is with a tensile test. The test measures the force as a function of the strain being applied to the plastic sample.

This test is very similar to the common astm d638 test whereby plastic material is pulled until in breaks in order to measure elongation tensile modulus tensile yield strength and. Iso 527 2 is performed on a universal testing machine by applying a tensile force to a sample specimen and measuring various properties of the specimen material under stress. Separate tensile test methods are commonly applied to polymer films astm d882 or iso 1184 and elastomers astm d412 or iso 37. Tensile testing of plastics astm d638 is one of the most common plastic strength specifications and covers the tensile properties of unreinforced and reinforced plastics.

Tensile testing may be based on a load value or elongation value. Tensile testing is commonly used to determine the maximum load tensile strength that a material or a product can withstand.
