Is there an Android API to test the physical memory or other hardware

I have tablets deployed in an enterprise situation. A handful of users have reported that their Android systems (GT2 7" LTE tablets) just shut off without warning. Since it's only a handful (4 or 5) out of many, I wanted to test to see if the memory or other hardware is failing and causing this strange behavior.

Is there a way to perform hardware tests in Android via an API? In particular, memory checksums? How about battery health? I have found nothing in the documentation so far that pertains to hardware except camera, sensors, etc..., but if someone could point me in the right direction...?

Since the tablets are out of warranty, I would like to test them myself, before shipping them to Samsung for inspection.
