Permeation: Rate by which a chemical can pass through the suit material on a molecular level through the process of absorption, diffusion, and desorption. 

Breakthrough Time: Time elapsed between initial chemical contact of the suit surface and detection of the chemical inside the suit.

* 1st number indicates breakthrough time in minutes.
* 2nd number indicates steady state permeation rate in UG/CM2/MIN

ND = None Detected
NR = Not Recommended
NT = Not Tested
