7.A.1.Accelerometers as follows and specially designed components therefor:

N.B. For angular or rotational accelerometers, see 7.A.1.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 7.A.1.a.1. and 7.A.1.a.2. do not apply to accelerometers limited to measurement of only vibration or shock.
b. Angular or rotational accelerometers, specified to function at linear acceleration levels exceeding 100 g.
