titleEquipment and Apparatus:

  •  Equipment: ball-interfaced and anvil interface micrometer, deflectometer, conditioning chamber, environmental test chamber are recommended but not required.

  • Apparatus: The machine will have a stationary and movable head, the machine should be able to indicate the total force being carried by the test specimen, it will either be a 3- or 4-point bend test. Below is what they used

titleProcedure:

  • Test at least five specimens.

  • Condition the specimen in a chamber if the test environment is not the same as a conditioned environment.

  •   Measure the length, width and thickness at three places in the specimen.

  • Place the specimeninto the test fixture and align the fixture so the longitudinal axis of the specimen is perpendicular (within 1 degree) to the longitudinal axes of the loading bars, the bars must also be parallel (within 1 degree) to the plane of the specimen facings.

  •   Attach the deflection transducer.

  • Apply a compressive force to the specimen until failure or until a deflection equal to the thickness is reached.

  • It was noted that the speed of testing should be around 6mm/min. 

  • Failure should occur at 3-6 minutes.
