Hi,
We understand that this information is not provided. We do apologize.
The information that may be available is on regards of temperature, which is the following (only for RDB2):
"RDB2 is designed for room temperature environment.
The board may work abnormally or be damaged in the high/low temperature test."
And about rugged (we think so?):

Still, help us contacting your local NXP representative/FAE/DFAE, since they may more information available than the one we have through this channel. We do apologize.
Please, let us know.
