Scope

1.1 This practice covers guidelines for using accelerometers in test vehicles to evaluate dynamic accelerations resulting from various maneuvers such as braking, accelerating, or cornering.

1.2 This practice is applicable to accelerometers that are rigidly attached to the body of the test vehicle or stabilized to the earth-fixed axis system by means of a gyroscope.

1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific precautions are given in Section 6.

Significance and Use

4.1 The measured accelerometer output can be used to calculate traction properties of combined tire-vehicle systems for passenger cars, light trucks, and heavy trucks through use of applicable methods of testing.

4.2 This practice is intended to achieve uniformity in test vehicle accelerometer use and in accelerometer signal processing. Through such usage, a basis for meaningful comparisons of test results from different sources will be obtained.

4.3 This practice is not applicable to accelerometers used in destructive testing, such as vehicle crash tests or vehicle vibration measurements.
