1.1 This test method specifies the test method for the tensile properties of plastic sheets and films (thickness less than 1.0 mm).
Note 1-The film is mandatory defined as a sheet with a rated thickness not greater than 0.25 mm (0.01 in).
Note 2â€”Plastics with a thickness greater than 1 mm (0.04 in) should be tested for tensile properties in accordance with the D 638 test method.
1.2 This test method can test all plastics that meet the above thickness and load range of the testing machine.
1.2.1 Static weighing of fixtures, and constant rate separation test-This test method uses fixtures separated at a constant rate to clamp both ends of the test sample.
1.3 This test method obtains the tensile degree of the test sample by the displacement of the separation clamp, the tensile indicator or the gauge line.
1.4 The measurement procedure of the elastic tensile coefficient, including a certain strain rate.
NOTE 3â€”The stretch factor is obtained by measuring the degree of stretch using a separate clip. The provisions for measuring with an extensometer as described in 5.2 are also included in this step.
1.5 The data obtained from this test method can be used in engineering design.
1.6 All values â€‹â€‹are in the International System of Units. The values â€‹â€‹in parentheses are for reference only.
1.7 This standard does not contain any safety issues related to the use of the standard (if any). Before using this standard, it is the user's responsibility to establish appropriate safety and health regulations and to establish restrictions on the use of the standard.
Note 4â€”This test method is similar to ISO 527-3, but technically the two cannot be equal. ISO 527-3 can use other types of samples with different test speeds and requires the use of extensometers or gauge wires.
