A – high resistance

B – good resistance; no, or only minor damage resulting from exposures of more than 30 days.

C – marginal resistance; for some types of plastic, extended exposure can result in damage (hairline cracks, loss of mechanicanical strength, discoloration, etc..)

D – non-resistant; exposure can lead to deformation or destruction.
