Superseded by IEEE 1293-1998. A guide for the preparation of a digital accelerometer specification and test procedure is provided. It is intended to provide common terminology and practice for manufacturers and users. The accelerometer considered utilizes a linear, single-axis, nongyroscopic accelerometer sensor with a permanent magnet torquer. The torquing electronics are considered part of the accelerometer. General design, performance, environmental, and reliability requirements are covered. Information on classification of tests, acceptance tests, qualification tests, reliability tests, standard test conditions, test equipment, test methods, and data submittal is given.

The specification and test requirements for a linear, single-axis, nongyroscopic accelerometer for use in inertial navigation, guidance, and leveling systems are defined. A standard specification guide and a compilation of recommended test procedures for such accelerometers are provided. Informative annexes are given on the various types of such accelerometers (force or pendulous torque rebalance with analog or digital output, vibrating beam, and micromechanical) and error effects, on filtering, noise, and transient analysis techniques, and on calibration and modeling techniques (multipoint tumble analysis, vibration and shock test analyses, and geophysical effects in inertial instrument testing).

This recommended practice provides a guide to the conduct and analysis of precision centrifuge tests of linear accelerometers and covers each phase of the tests, beginning with the planning. Possible error sources and typical methods of data analysis are addressed. The intent is to provide users involved in centrifuge testing with a detailed understanding of the various factors affecting accuracy of measurement, both factors associated with the centrifuge and factors in the data collection process. Model equations are discussed, both for the centrifuge and for a typical linear accelerometer, each with the complexity needed to accommodate the various identified characteristics and error sources in each. An iterative matrix equation solution is presented for deriving the various model equation coefficients for the accelerometer under test from the centrifuge test data. Keywords: accelerometer, accelerometer test, centrifuge, linear accelerometer.
