This recommended practice describes the conduct and analysis of precision tests that are to be performed on linear accelerometers using centrifuge techniques. The term precision, in this context, refers to tests that are conducted to evaluate accelerometer parameters, as opposed to those conducted to establish environmental survivability only. Evaluation may take the form of determining the coefficients of the accelerometers model equation, except for bias and scale factor, which are most accurately determined by static multi-position tests. Alternatively, evaluation may only establish that the accelerometer output complies with specific error limit criteria. |
