7A001Accelerometers 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.
b. Angular or rotational accelerometers, specified to function at linear acceleration levels exceeding 100 g.
