ASTM
Cynthia,
Yes, ASTM is the American Society for Testing & Materials. I'm on the subcommittee for artists' materials. I will be writing a lightfastness standard for artists' pastels, with lots of help. We are currently conducting some accelerated-aging tests on them, at my urging, but I shouldn't report results until the tests have run their course.
