**6.4 Compression testing of samples**

The specimens for compression test are rough-cut cubes out of bone with the orientation of specimens maintained along the axis of the long bone. During the test, bone is kept at room temperature (24°C) in wet conditions. During testing, care is taken to ensure that the test specimens are kept hydrated. Three cubic samples were obtained from one femur bone. Out of three cubic samples, one sample was kept along the direction of fibers i.e. along the longitudinal axis of bone for compression test as shown in **Figure 3**. The other two samples were used to measure the compression strength of femur bone in the transverse direction shown in **Figure 3**.
