Accelerometers as follows and specially designed components therefor: N.B.: SEE ALSO 7A101. N.B.: For angular or rotational accelerometers, see 7A001.b. a. Linear accelerometers having any of the following: 1. Specified to function at linear acceleration levels less than or equal to 15 g and having any of the following: a. A “bias”“stability” of less (better) than 130 micro g with respect to a fixed calibration value over a period of one year; or b. A “scale factor”“stability” of less (better) than 130 ppm with respect to a fixed calibration value over a period of one year; 2. Specified to function at linear acceleration levels exceeding 15 g but less than or equal to 100 g and having all of the following: a. A “bias”“repeatability” of less (better) than 1 250 micro g over a period of one year; and b. A “scale factor”“repeatability” of less (better) than 1 250 ppm over a period of one year; or 3. Designed for use in inertial navigation or guidance systems and specified to function at linear acceleration levels exceeding 100 g; Note: 7A001.a.1. and 7A001.a.2. do not control accelerometers limited to measurement of only vibration or shock.

Notes
- Linear accelerometers, designed for use in inertial navigation systems or in guidance systems of all types, usable in the systems specified in 1.A., 19.A.1. or 19.A.2., having all of the following characteristics, and specially designed components therefor: a. ‘Scale factor’‘repeatability’ less (better) than 1 250 ppm; and b. ‘Bias’‘repeatability’ less (better) than 1 250 micro g. Note: Item 9.A.3. does not control accelerometers specially designed and developed as Measurement While Drilling (MWD) sensors for use in downhole well service operations. Technical Notes: 1. ‘Bias’ is defined as the accelerometer output when no acceleration is applied. 2. ‘Scale factor’ is defined as the ratio of change in output to a change in the input. 3. The measurement of ‘bias’ and ‘scale factor’ refers to one sigma standard deviation with respect to a fixed calibration over a period of one year. 4. ‘Repeatability’ is defined according to IEEE Standard for Inertial Sensor Terminology 528-2001 in the Definitions section paragraph 2.214 titled repeatability (gyro, accelerometer) as follows: ‘The closeness of agreement among repeated measurements of the same variable under the same operating conditions when changes in conditions or non-operating periods occur between measurements’.
- Accelerometers or gyros of any type, designed for use in inertial navigation systems or in guidance systems of all types, specified to function at acceleration levels greater than 100 g, and specially designed components therefor.Note:9.A.5. does not include accelerometers that are designed to measure vibration or shock.
