ABSTRACT. THIS PAPER PRESENTS 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 METROLOGÍA (CENAM - MEXICO), INSTITUTO NACIONAL DE METROLOGIA, NORMALIZAÇÃO E QUALIDADE INDUSTRIAL (INMETRO - BRAZIL) AND INSTITUTO NACIONAL DE TECNOLOGÍA INDUSTRIAL (INTI - ARGENTINA). CALIBRATIONS OF THREE STANDARD ACCELEROMETERS BY LASER-INTERFEROMETRY 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 CALIBRATION OF THE ACCELEROMETERS ARE GIVEN IN THIS PAPER.
KEYWORDS: ACCELEROMETER, CALIBRATION, INTERCOMPARISON, INTERFEROMETRY.
