1. Linear accelerometers having any of the following characteristics:
   
   
   1. Specified to function at linear acceleration levels less than or equal to 15 g and having:
      
      
      1. A "bias" "stability" of less (better) than 130 micro g with respect to a fixed calibration value over a period of one year; or
         
         
      2. 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:  (L.N. 161 of 2011)
      
      
      1. A "bias" "repeatability" of less (better) than 5000 micro g over a period of one year; and
      2. A "scale factor" "repeatability" of less (better) than 2500 ppm over a period of one year;
      
      
   3. 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)
      
      
2. Angular or rotational accelerometers, specified to function at linear acceleration levels exceeding 100 g;
