The present invention relates to a force testing machine (FTM) validation apparatus (1) for validating a test process involving a force testing machine to measure forces involved in operation of a syringe arrangement (7), particularly a syringe arrangement (7) comprising a staked-in needle prefilled syringe (8) and a needle safety device (9, 9', 9'') cooperating with the staked-in needle prefilled syringe (8). The FTM validation apparatus (1) comprises a syringe arrangement surrogate (2) and a holder (3) arranged to support the syringe arrangement surrogate (2) in a predefined position and orientation in the force testing machine. The syringe arrangement surrogate (2) comprises a break loose part (4) arranged to mimic a break loose force of the syringe arrangement (7) and an injection force part (5) arranged to mimic an injection force of the syringe arrangement. The present invention also relates to a method of validating a test process involving a force testing machine to measure forces involved in operation of a syringe arrangement (7), by the above FTM validation apparatus (1)； as well as to a method for measuring forces involved in operation of the syringe arrangement (7) comprising a test process validated according to the mentioned validation method.
