scope:

This specification defines requirements for [accelerometer type].

This specification format guide and test procedure standard applies to force-rebalance accelerometers (pendulous or translational proof mass), vibrating beam accelerometers (VBAs), and micromechanical accelerometers that range from lesser accuracy to high-accuracy devices (see 5.1).

All accelerometers have biases, scale factors, misalignments, nonlinearities, noise characteristics, and other parameters. Many of the specification requirements and verification test methods for these parameters; their stabilities; their temperature, magnetic, and other sensitivities; the accelerometer behavior through and across vibration, shock, and other environments; and the accelerometer lifetime and reliability are independent of the accelerometer type. Requirements and tests that are specific to a particular accelerometer type are described separately.

Only the clauses applicable to the given accelerometer type should be used.

This specification is not intended to define requirements for the pendulous integrating gyroscopic accelerometer (PIGA) or for the specific force integrating receiver (SFIR). These high-precision single degree-of-freedom (DOF) accelerometers use gyroscopic precessional torque to rebalance the specific force effect of nongravitational acceleration acting on a pendulous proof mass on the gyro float.

This specification also does not apply to devices (such as seismometers or open-loop piezoelectric accelerometers) that measure ac rather than low-pass and dc accelerations. Gravimeters having a limited dc measurement range around +1 g with input axis (IA) vertical are also not considered.

Purpose

This specification describes the design and performance requirements for [model number, part number, change letter (if any), other identification], manufactured by [name, address].
