N.B.:
For angular or rotational accelerometers, see 7A001(b). See also 7A101.
- Linear accelerometers having any of the following characteristics:
- Specified to function at linear acceleration levels less than or equal to 15 g and having:
- A "bias" "stability" of less (better) than 130 micro g with respect to a fixed calibration value over a period of one year; or
- A "scale factor" "stability" of less (better) than 130 ppm with respect to a fixed calibration value over a period of one year;
- Specified to function at linear acceleration levels exceeding 15 g but less than or equal to 100 g and having all of the following: (L.N. 161 of 2011)
- A "bias" "repeatability" of less (better) than 5000 micro g over a period of one year; and
- A "scale factor" "repeatability" of less (better) than 2500 ppm over a period of one year;
- Designed for use in inertial navigation or guidance systems and specified to function at linear acceleration levels exceeding 100 g; and
Note:
7A001(a)(1) and 7A001(a)(2) do not apply to accelerometers limited to measurement of only vibration or shock. (L.N. 161 of 2011)
- Angular or rotational accelerometers, specified to function at linear acceleration levels exceeding 100 g;
