The AutoX is a high-resolution, long-travel automatic contacting extensometer.

Clip-on extensometers such as or astmm to a deflectometer plunger also meet Class C deflection measuring requirements. A support span-to-depth ratio of Email addresses can only contain letters, numbers and the following special characters: Software for Series Systems. For the four point flexural test, the specimen lies on a span and stress is uniformly distributed between the loading noses. The test method is used for reinforced or unreinforced materials including high modulus composites and for materials that asym not fail within the limits of ASTM D a three point loading test.

This test method utilizes a four point loading system applied to a simply supported beam.

The chamber is designed to allow the test mounts from the base and crosshead of the Tester to pass through the top and bottom of the chamber. This standard has either been superseded and replaced by a new version or discontinued. 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.

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. 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.

This is extended to intersect the strain axis at Point B8, the corrected zero-strain point. NOTE 6—Use of the formulas for simple beams cited in these test methods for calculating results presumes that beam width is small in comparison with the support span.

For a load span of one half of the support span: Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill.
