The National Institute of Metrology,as pilot laboratory for the first international key comparison for shock acceleration(CCAUV.V-K4)is proposed.Technical protocol is illustrated by combination of dynamic characteristics of shock acceleration measuring chain and spectral contents of shock excitation.Three different approaches are used to calculate the reference value of comparison,including recommended method by international comparison and two methods based on Bayesian inference.It is argued that Bayesian approach with different statistical model is compatible with the practice of metrology,with different prior distribution and MCMC method to obtain the posterior distribution.The equivalence and divergence of three methods are illustrated through comparison of results obtained.
