Compression springs are coil springs wound with spacing between the coils so that they can be compressed from their freelength to a shorter operating length to store energy or provide a force.
Performance tests consist of incremental loading and unloading of anchors to verify sufficient capacity to resist the test load verify the freelength and evaluate the permanent set of the anchor.
