Standard Test Method for Tensile Properties of Reinforced Thermosetting Plastics Using Straight-Sided Specimens
|Publication Date:||15 March 2017|
|ICS Code (Laminated sheets):||83.140.20|
This test method covers the determination of the tensile properties of thermosetting reinforced plastics using test specimens of uniform nominal width when tested under defined conditions of pretreatment, temperature, humidity, and testingmachine speed.
NOTE 1-Experience with this test method to date has been limited to glass-reinforced thermosets. Applicability to other materials remains to be determined.
This test method is used for testing materials of any thickness up to 14 mm (0.55 in.).
NOTE 2-This test method is not intended to cover precise physical procedures. It is recognized that the constant-rate-of-cro
Test data obtained by this test method is relevant and appropriate for use in engineering design.
The values stated in SI units are to be regarded as standard. The inch-pound units given in parentheses are for information only.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
NOTE 4-This standard and ISO 527-4 address the same subject matter, but differ in technical content.
This test method does not include testing of the Type I dogbone shaped specimen described in ISO 527-4. Testing of this type of specimen, primarily used for reinforced and un-reinforced thermoplastic materials, is described in Test Method D638.
The thickness of test specimens in this test method includes the 2 mm to 10 mm thickness range of ISO 527-4, but expands the allowable test thickness to 14 mm.
ISO 527-4 allows for the use of holes in the tabs of the test specimen while this standard does not.
The definitions for tensile strength and modulus differ between these two standards.
NOTE 5-For tensile properties of resin-matrix composites reinforced with oriented continuous or discontinuous high modulus > 20-GPa (> 3.0 × 106 -psi) fibers, tests shall be made in accordance with Test Method D3039/D3039M or ISO 527 Part 5.
