ASTM D747 -10 Standard Test Method for Apparent Bending Modulus of Plastics by Means of a Cantilever Beam (Withdrawn 2019) Format Pages Price PDF 6 $62. 00 ADD TO CART Withdrawn Rationale: This test method covers the determination of the apparent bending modulus of plastics by means of a cantilever beam. It is well suited for determining relative flexibility of materials over a wide range. It is particularly useful for materials too flexible to be tested by Test Methods D790. Formerly under the jurisdiction of Committee D20 on Plastics, this test method was withdrawn in January 2019 in accordance with section 10. 6. 3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date. 1. Scope 1. 1 This test method covers the determination of the apparent bending modulus of plastics by means of a cantilever beam.
ASTM D747 - 99 Standard Test Method for Apparent Bending Modulus of Plastics by Means of a Cantilever Beam
Description: TECHNOLOGY AREA(S): Materials, Chem Bio Defense, Human Systems OBJECTIVE: Current, state-of-the-art Chemical, Biological, Radioactive, and Nuclear (CBRN) protective gloves are highly protective (butyl rubber) and durable [1], but are bulky and induce an elevated thermal burden when worn for extended fit, sizing, and physical bulk of gloves is critical to avoid restricting user dexterity, which is needed to perform tasks in high risk environments [2, 3] increased thermal burden associated with wear decreases user comfort and acceptance [4].
ASTM D747, 2010 Edition, April 1, 2010 - Standard Test Method for Apparent Bending Modulus of Plastics by Means of a Cantilever Beam This test method covers the determination of the apparent bending modulus 2 of plastics by means of a cantilever beam. It is well suited for determining relative flexibility of materials over a wide range. It is particularly useful for materials too flexible to be tested by Test Methods D 790. The values stated in SI units are to be regarded as the standard. The values 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 1—There is no known ISO equivalent to this standard. 2 This property was designated stiffness in versions of this test method issued prior to 1984. *A Summary of Changes section appears at the end of this standard.

ASTM D747 is used to determine the flexibility of plastics by means of a cantilever beam. It measures flexibility, or apparent bending modulus, when test specimens are supported as a cantilevered beam and are deflected through an angle of force and angle of bend of the specimen. Note this test standard was withdrawn in 2019 and not replaced. Before conducting ASTM D747, it is important to read the entire specification. Standards can be obtained from appropriate standard authorities. Speak to an expert Got a question about a product? Request a call back from one of our Technical Sales Engineers now.
