It shall be used for measurement of flexural properties, particularly flexural modulus, unless the material specification states otherwise.

ASTM D testing measures force, center span displacement and strain in four-point bending. Advanced strain solutions include non-contacting extensometers, such as the Advanced Video Extensometer AVE 2 and automatic contacting extensometers, such as the AutoX How can we help you?

Bluehill Universal Software is built from the ground-up for touch interaction and an intuitive user experience. Next Checking to see if you are a returning visitor…. ASTM D is a testing specification that determines the flexural properties of unreinforced and reinforced rigid and semi rigid plastics.

Repeatability of calculations — When setting up the test, having an adequate preload is highly recommended to ensure astn and consistent strain measurements. Stop the test at specimen break.

These materials include high-modulus composites and electrical insulating sstm. By continuing to use our site, you accept our cookie policy. The chamber has internal electric heaters for elevated temperatures and uses external carbon dioxide gas as a coolant for reduced temperatures.

ASTM D6272 Plastic and Insulating Material Flexural Testing

It is well suited for applications involving plastics, metals, biomedical, composites, elastomers, and more. Please confirm that you agree with our privacy and cookies policy to submit this form.

Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups: Subscribe to Instron News! Historical Version s – view previous versions of standard. This test method covers two procedures: Rate of d6722 displacement R must be calculated using the equations in the standard.

Procedure B is followed for materials with larger deflections and used for measuring strength. In four point bending the maximum axial fiber stress is uniformly awtm between the loading noses.

Procedure A is followed for materials with smaller deflection and for measuring modulus. It is important to review ASTM D in order to fully understand the test axtm, procedure, and results requirements.

The values provided in parentheses are for information only. The major difference between the three point and four point flexural tests is the location of the bending moment.


These test methods are generally applicable to rigid and semirigid materials. Flexural properties vary with factors such as specimen depth, temperature and the difference in rate of straining. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill. In three point bending the maximum axial fiber stress is located immediately under the loading nose.

The amount of force applied to the specimen prior to starting the test directly impacts the repeatability of calculations, such as flexural modulus.

For this reason and other differences in technical content, exercise extreme care if attempting ast, compare results between the two test methods. For the four point flexural test, the specimen lies on a span and stress is uniformly distributed between the loading noses. Select from list below: Alternatively, slack correction can be used to ensure that the calculations are performed on the appropriate section of the testing data. A bar of rectangular cross section is mounted on a four point axtm fixture and is loaded at two points.
