Correct, the test done by TLARGI is for swell of rubbers by immersion for an extended time. This is obviously different than a glove permeation test in minutes.
The point I trying to make is that if the chemical you are interested in is not listed on a glove chart, then you could use the TLARGI chart as a starting point to understand which glove type could potentially be used and which won't have
a shot. You'd still have to do the permeation test to determine the required glove thickness and understand maximum wear time.
Also, the TLARGI chart is commonly referenced in industry for rubber selection. Materials with a rating of 1 are considered suitable for long term service. So, researchers can also use it to select elastomers for experimental set-ups and
replacement parts in old equipment.
Thank you,

Interesting, but it appears that it is resistance and not permeation they are testing for. Some chemicals go through polymers without showing any signs of having
done so. They appear unchanged and would appear to have good resistance to chemical damage. So the ASTM test for permeability in minutes is what I recommend for use. Every manufacturer also has information on resistance and degradation, but you can almost
detect that yourself with observation.

I addition to everyone's fantastic advice, I'd like to point out that the ACS Rubber Division's Los Angeles Rubber Group developed a chemical resistance chart for
rubber materials. This chart can be useful when the subject chemical is not listed in the manufacturer's glove chart. At a bare minimum, it will give you an indication of potential issues with various glove types.
You can find the chart at their website
https://tlargi.org/media/2019/01/TLARGI_Chemical_Resistance_Chart.pdf
Also, the chart is also available as a searchable database hosted by Dupont at

Thank you to everyone who provided useful answers and resources on this thread. As always, it is interesting to see how seasoned professionals take on even the most
basic of questions. Also, I always enjoy reading the historical perspectives that several members here bring to discussions like these. As you well know, newbies benefit far more from mentorship than a Google search.
