Flexural Properties by Four-Point Bending ASTM D

zstm Select from list below: Next Checking to see if you are a returning visitor…. Repeatability of calculations — When setting up the test, having an adequate preload is highly recommended to ensure accurate and consistent strain measurements.

Flexural strain measurement — ASTM D requires that the method used to measure strain is not influenced by the compliance of the machine. Contact Us Request an Accessory Catalog.

ASTM D6272 Flexural Properties of Plastics and Electrical Insulating Materials

Any test specimen preparation, conditioning, dimensions, or testing parameters covered in the material specification, or both, shall take precedence over those mentioned in this test method. Apply flexural load at calculated crosshead displacement rate R.

ASTM D Plastic and Insulating Material Flexural Testing – ADMET

The AutoX is a high-resolution, long-travel automatic contacting extensometer. Touchstone Research Aatm, Ltd. A bar of rectangular cross section is mounted on a four point bend fixture and is loaded at two points. Historical Version s – view previous versions of standard.


ASTM D is a test method for the determinations of flexural properties for unreinforced and reinforced plastics. Check this box to receive pertinent commercial email from Instron focusing on products, upcoming events, and more!

Elevated or Reduced Temperature Test Procedure: Procedure B is followed for materials with larger deflections and used for measuring strength.

We’re happy to help!

For this reason and other differences in technical content, exercise extreme care if attempting to compare results between the two test d622. Five specimens are typically tested. The light-weight, rugged cross-brace design eliminates errors caused by physical distortion, while built-in protection ensures that damage is not caused by over-extension.

Procedure A is used for brittle materials that break at low deflections. Load span to support span can be a ratio of 1 to 2 or 1 to 3.

Advanced strain solutions include non-contacting extensometers, such as the Advanced Video Extensometer AVE 2 and automatic contacting extensometers, such as the AutoX The second generation Advanced Video Extensometer AVE 2 utilizes patented measurement technology in the fastest, most accurate non-contacting strain measurement device commercially available. This test method covers the determination of unreinforced and reinforced plastics, including high-modulus composites and electrical insulating materials in the form of rectangular bars molded directly or cut from sheets, plates or molded shapes.

ASTM D6272 Plastic and Insulating Material Flexural Testing

This flexure test requires a 4 point fixture where the bottom span is set by the span-to-depth of Due to copyright restrictions, we are not able to provide copies of standards. For anisotropic materials, flatwise and edgewise specimens may be tested.


The chamber is designed to allow the test mounts from the v6272 and crosshead of the Tester to pass through the top and bottom of the chamber. These materials asfm high-modulus composites and electrical insulating materials.

How can we help you? ASTM D testing measures force, center span displacement and strain in four-point bending. They are designed with standard and optional features that increase testing efficiency and axtm the testing experience for the operator.

Procedure B is used for flexible, more ductile materials that undergo large deflections. ICS Number Code The major difference between four point and three point bending modes is the location of the maximum bending moment and maximum axial fiber stress.

Since the flexural properties of many materials can vary depending on temperature, rate of strain and specimen thickness, it may be appropriate to test materials at varied parameters. In four point bending the maximum axial fiber stress is uniformly distributed between the loading noses.

The series of extensometers offers speed of attachment and ease-of-use.
