ISO 178 flexural testing is typically run using a 3-point bending setup, and dedicated bending fixtures are available for use with this UTM grip and fixture lineup.

For ISO 178 work, the common approach is a 3-point flexural fixture with a loading nose and two supports, with span adjustment to match the method and your specimen geometry. If you also run other flexural methods, 3-point and 4-point bending fixtures are available as well, depending on whether you need a standard bend setup or a more specialized uniform-moment configuration.

Final ISO 178 fit depends on your specific method details, especially specimen thickness and width, required support span, and the contact geometry at the loading nose and supports, plus how you plan to capture deflection or strain for modulus reporting.
