Model: #GF1717

GF1717 test fixtures hold the UHMWPE blocks square at the ASTM recommended spacing during assembly and screw tightening modes on bio-lateral lumbar constructs. This feature has proven to be helpful in maintaining consistent test results during ASTM F1717 testing applications.

Model: #GF2077

ASTM F2077 includes three different test methods including compression, compression-shear and torsion. All three types of fixtures are available.

Procedure A of ASTM D7774

‍For Procedure A requires a three point bending fixture. A specimen of rectangular cross section is braced by two double-sided supports and is loaded by means of a double-sided loading nose midway between the supports. A support span-to-depth ratio of 16:1 is used.

The specimen is cyclically loaded equally in the positive and negative directions to a specific stress or strain level at a uniform frequency until the specimen ruptures or yields.

Procedure B of ASTM D7774

‍For Procedure B a 4 point bend fixture is required. A specimen of rectangular cross section is braced by two double-sided supports and is loaded by means of two double-sided loading noses, each an equal distance from the adjacent support. Load span-to-support span ratios can be 1:2 or 1:3.

The specimen is cyclically loaded equally in the positive and negative directions to a specific stress or strain level at a uniform frequency until the specimen ruptures or yields.
