Self aligning compression platens helps minimize errors from non parallel top and bottom specimen surfaces. These spherical seated compression platens self align with compression test specimens that have top and bottom surfaces that are not completely parallel. The hardened steel (58 HRC) platen is mounted to the crosshead or baseplate of the test frame, and typically used with a fixed (or plane) compression platen. They are available with optional test machine adapters to enable them to be used with virtually any test machine. The platen's concentric circles help the operator center the test specimen, increasing test result validity.

The spherically seated platens accommodate up to 3 degrees of angular displacement of the top of the specimen with reference to the machine’s loading axis. They enable parallelism during specimen failure.
