Hi Doug,
I think you will find that the common mineral spirit found in your local
hardware store is used by most companies to perform the test in order to get
a good idea if the label and print will pass. I have found that UL will
accept the results. By the way, the gallon of mineral spirits I have at home
is also labeled "petroleum spirit". If you are doubtful of this test result,
you may want to have an agency such as UL do the test for you or use an
approved label system.
In my experience I have found mineral spirit to be a more harsh chemical
than Isopropyl Alcohol. The alcohol test is performed on labels that are
used in medical environments per IEC 60601.

Subject: Label Rub test per IEC60950

Does anyone know what the trade name for the chemical used for the rub test
in 60950 clause 1.7.15 is ?
The standard calls it "petroleum spirit", then describes an aliphatic
solvent hexane, with several properties, none of which are a chemical
formula.
Is it common mineral spirits available at most hardware stores?
Also, is Isopropyl Alcohol a more harsh solvent than the petroleum spirits?
Thanks
