This paper presents the preliminary results obtained in an international intercomparison of the calibration of acceleration standards by participating laboratories of the Inter-American Metrology System (SIM). Participating laboratories were the National Metrology Institutes of five american countries, i.e., National Institute of Standards and Technology (NIST - U.S.A.), National Research Council (NRC - Canada), Centro Nacional de Metrolog a (CENAM - Mexico), Instituto Nacional de Metrologia, Normaliza o e Qualidade Industrial (INMETRO - Brazil) and Instituto Nacional de Tecnolog a Industrial (INTI - Argentina). Interferometric calibrations of three standard accelerometers and calibration of a signal conditioner were performed by each of the participating laboratories. A brief description of the experimental procedures and preliminary results for the accelerometers calibration are given in this paper.
