ASTM A – 03 Standard Specification for Ductile Iron Gravity Sewer Pipe

By continuing to use our site, you accept our cookie policy. When conducting acceptance tensile testing of ductile asm as specified by ASTM Ait is necessary to test machined specimens. This specimen is known as a shouldered-end specimen. Sometimes referred to as a “dumbbell”, “dogbone” or “button-end specimen”, this round specimen type has shouldered ends that are used for gripping the specimen during testing.

Modern ASTM A tests need to be run at specific stress rates under servo control and require an extensometer for accurate calculation of 0. These contemporary needs make older testing techniques, such as manual pacing or drop-of-beam observations, unsuitable. We a74 provided systems for tensile testing standard 0.

ASTM A746 Standard Specification

Since the maximum load requirement for these sizes is approximately 30, lbf, we recommend using an Industrial Series LX load frame with split insert tensile grips and holders. These tensile grips are designed specifically for testing ductile iron specimens and adapt axtm the test frame with our Universal Spherical Tension Adapters USTA.

The USTA adapters ;provide necessary specimen alignment. The single test space and dual acting actuator of the LX make it easy for operators to install the specimens. The split sleeve shouldered end specimen holders allow for quick changing of test specimens. They also contain the ends of the a764 specimen during failure providing an extra level of operator safety.
