Standard Test Method for Tensile Properties of Reinforced Thermosetting Plastics Using Straight-Sided Specimens
|Publication Date:||10 April 2002|
|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 testing-machine 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 can be 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
NOTE 3 - Use of this test method for testing materials of thicknesses greater than 14 mm (0.55 in.) is not recommended. Reducing the thickness by machining may be acceptable for materials of uniform reinforcement amount and direction, but is generally not recommended.
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 test method is technically equivalent to ISO 527-4 except as noted below:
(a) 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 D 638.
(b) 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.
NOTE 5 - For tensile properties of resin-matrix composites reinforced with oriented continuous or discontinuous high modulus > 20-Gpa (> 3.0 × 10 6-psi) fibers, tests shall be made in accordance with Test Method D 3039 or ISO 527 Part 5.
