A dynamic force transfer standard is designed at PTB to provide the traceability to dynamic testing metrology field. This contribution describes a method of evaluation the uncertainty of the primary dynamic force calibration of transfer standards, including the description of the uncertainty models of the sensitivity, which is the main measurand. Some influences have been reduced like the effect of the misalignment and telting effects. Other new contributions have been introduced like the contribution of the acceleration distribution correction due to elastic deformation of load masses, Sine fit, and vibration isolation of the laser vibrometer. A comparison between the estimation of uncertainty using classical GUM technique and Monte Carlo simulation has been performed.
