ADIS16448 Weight

I recently weighed 5 ADIS16448 IMUs using a calibrated digital scale with resolution of 0.1 grams.  The IMUs have date codes from 2013.  The results are below:

Mean =      12.62g

Std: =         0.13g

The data sheet (Rev. C) specifies 15g.  Thought this might be helpful information for some (~15% lower than spec.).

Does anyone else have similar information for more recently manufactured units?
