(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 D638.
(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.
(c) ISO 527-4 allows for the use of holes in the tabs of the test specimen while this standard does not.
(d) The definitions for tensile strength and modulus differ between these two standards.
