Superseded by 836-2001. A guide to the conduct and analysis of precision centrifuge tests of linear accelerometers is provided, covering 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 those involved in centrifuge testing with a detailed understanding of the various factors affecting accuracy of measurement, both those associated with the centrifuge and those 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. A new iterative matrix equation solution for deriving from the centrifuge test data the various model equation coefficeints for the accelerometer under test is presented.

Superseded by IEEE 1293-1998.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.

IEEE Std 671-1985 provides specifications and test requirements for a non-gyroscopic inertial angular sensor that may measure angular jerk, acceleration, rate, or displacement with or without response down to zero frequency. A standard specification format is provided. A compilation of recommended test procedures, derived from those presently used in the industry, is also provided. Informative annexes cover design features and theoretical principles of operation. This corrigendum makes changes to 4.7.2.6 to delete a sentence that does not belong there, to add a subclause that was inadvertently left out, and to renumber the existing subclauses. Changes are also being made to fix the block diagrams in Annex A, to correct a misspelling of inertia, and to add a missing symbol.
