Demystify: 

you also have to take into account the glove thickness, which could vary by brand. Some nitrile gloves are 4 mm, others 8 mm...

I don't think I would want a generic chart, so much depends on the mfg. And they have quite a bit of incentive to get it right...$$$$$

My two cents...

Caution: If you are going to be citing the NIOSH Recommendations for Chemical Protective Clothing for glove guidance - check when it was published, it is severely dated.

Monona is right, look at the individual glove manufacturer for testing permeation and degradation information. If you do a Google search, you=E2=80™ll end up with generic information that will be unreliable - depending upon which glove has been specified.

Suppliers and Google will provide generic "data" but nothing I would rely upon when you really need to confirm adequate protection.

It=E2=80™s late and I can't remember the name of the organic chemist who started the testing work at Ansell. He developed the first spreadsheet, which later turned into their database. When I ran into a new molecule that was going to be tested for toxicity as an investigational new drug, if he could not refer to a very close analog to provide protection, I could send him a sample and he would test to provide a recommendation. It depends upon what you are trying to protect against. Is a generic, possibly diluted level of protection adequate or are you trying to protect from a true hazard?
