Scope: Tensile tests measure the force required to break a specimen and the extent to which the specimen stretches or elongates to that breaking point.

Tensile tests produce a stress-strain diagram, which is used to determine tensile modulus. The data is often used to specify a material, to design parts to withstand application force and as a quality control check of materials. Since the physical properties of many materials especially thermoplastics can vary depending on ambient temperature, it is sometimes appropriate to test materials at temperatures that simulate the intended end use environment.

Test Procedure: Specimens are placed in the grips of the Universal Tester and pulled until failure. For ASTM D the test speed and grip separation are based on the elongation to break of the material. Elongation and tensile modulus can be calculated from crosshead displacement, or with an extensometer. The chamber is designed to allow the test mounts from the base and crosshead of the Universal Tester to pass through the top and bottom of the chamber.

Standard test fixtures are installed inside the chamber, and testing is conducted inside the controlled thermal environment the same as it would be at ambient temperature.

The chamber has internal electric heaters for elevated temperatures and uses external carbon dioxide gas as a coolant for reduced temperatures. The size of the chamber places a limitation on the maximum elongation that can be reached.

Data: The following calculations can be made from tensile test results:. Standards can be obtained from appropriate standard authorities. Intertek Global Website.

How to Perform an ASTM D882 Plastic Film Tensile Strength Test

This test is very similar to the common ASTM D test whereby plastic material is pulled until in breaks in order to measure elongation, tensile modulus, tensile yield strength, and tensile strength at break. However, it is designed specifically for thin sheeting and film less than 1 mm 0. This reduces the cost of the testing system and simplifies the testing process. The two main things to keep in mind in regards to equipment are the height of the testing machine and having grips designed to hold the thin film correctly.

Tensile Properties (Sheet) ASTM D882

Standard Test Method for Tensile Properties of Thin Plastic Sheeting1 This standard is issued under the fixed designation D ; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon e indicates an editorial change since the last revision or reapproval. These test methods have been approved for use by agencies of the Department of Defense to replace Method of Federal Test Method Standard ISO allows for additional specimen configu- rations, specifies different test speeds, and requires an extensometer or 1.
