\nPlastics, polymers and composites can be tensile tested to measure product quality. Tensile tests measure the load required to break a plastic test sample and specimen stretch or elongation to that breaking load. The resulting test data helps specify materials, design parts to withstand forces, and key quality control checks for materials. Plastic composite tensile test equipment, testers and electromechanical universal test machines feature constant rate of crosshead extension or CRE because plastics tensile test behavior is time rate test speed dependent. Plastic tensile coupons (dogbone-shaped specimens with defined width and load stress psi) are made to ASTM, EN, DIN and ISO tensile test sample dimensions. Plastics composite tensile tester machine speed should always rely on standard specifications. Plastic tensile test standards ASTM D638 and ISO 527 both require axial extensometers to measure strain below 20 percent extension values. High travel or strain can be measured by the machine crosshead or digital encoder. Thin film sheet samples should follow ASTM D882.
\nApplicable Testing Standards
\n\u2022 ISO 527 \u2013 Tensile Test of Plastics Composites
\n\u2022 ASTM D638 Tension Testing for Plastics
\n\u2022 ASTM D882 Tensile Testing for Thin Plastic Sheeting
\n\u2022 ASTM D3039 Tensile Testing for Advanced Composite Materials
\nASTM D638 Tension Testing for Plastics
\nASTM D638 is one of the most common plastic strength specifications and covers the tensile properties of unreinforced and reinforced plastics. This test method uses standard \u201cdumbell\u201d or \u201cdogbone\u201d shaped specimens under 14mm of thickness. A universal testing machine (tensile testing machine) is needed to perform this test.
\nTest Procedure:
\n1. Cut or injection mold your material into one of the five \u201cdumbbell\u201d shapes. The exact shape you use is dependent upon your material\u2019s rigidity and thickness.
\n2. Load the specimen into tensile grips.
\n3. Attach the extensometer to the sample
\n4. Begin the test by separating the tensile grips at a constant rate of speed. Speed depends on specimen shape and can range from 0.05 \u2013 20 inches per minute. The target time from start of test to break should be from 30 seconds to 5 minutes.
\n5. End the test after sample break (rupture)
