| SYMBOLIC RATING |
VOLUMETRIC SWELLING | LOSS OF TENSILE STRENGTH | DESCRIPTION OF ATTACK |
| A | < 15% in 30 days to 1 year | < 15% in 30 days to 1 year | Excellent, little or no swelling or softening or surface deterioration. |
| B | < 30% in 30 days to 1 year | < 30% in 30 days to 1 year | Good chemical resistance. Minor chemical attack, swelling, softening or surface deterioration. |
| C | < 50% in 30 days to 1 year | < 60% in 30 days to 1 year | Limited chemical resistance. Moderate chemical attack. Conditional service. |
| NR | > 50% immediately to 1 year | > 60% immediately to 1 year | Severe attack, swelling, softening, or dissolved within minutes to years. Not recommended. |
| Q | - | - | Questionable resistance. Doubtful usage. |
| TEST | - | - | Test before using. |
| A to 70°F | < 15% volume increase or < 15% loss of tensile strength at 100% concentration or concentrated or saturated solution to 70°F. Little or no chemical attack. |
| A to 100% to 70°F | < 15% volume increase or < 15% loss of tensile strength in any concentration from 0 to 100% at 70°F. Little or no chemical attack. |
| A to 20% to 70°F | < 15% volume increase or < 15% loss of tensile strength in any concentration from 0 to 20% at 70°F. Little or no chemical attack. |
| B 20-50% 70-140°F | < 15 to 30% volume increase or 15 to 30% loss of tensile strength, from 20% to 50% concentration of solution between 70°F and 140°F. |
| B to conc to 212°F | < 15 to 30% volume increase or 15 to 30% loss of tensile strength, in any concentration to 100% at any temperature from 70°F to 212°F. |
| AC at 70°F | 0% to 30% volume increase, or 0% to 30% loss of tensile strength at 100% concentration or concentrated, or saturated solution, at 70°F. Reported data varies widely possibly due to compounding differences within the same generic family. |
| NR at 70°F | > 50% volume increase or > 60% loss of tensile strength at 100% concentration, or concentrated, or saturated solution at 70°F. Severe attack. Not recommended. |
| A/NR at 70°F | 15% to > 50% volume increase or < 15% to > 60% loss of tensile strength at 100% concentration, or concentrated, or saturated solution at 70°F. Varying or variable rates reported by multiple sources. Use only after specific testing of all parameters to be encountered. |

Maximum use temperatures listed are not necessarily upper limits of usability, but are limits of data available at time of printing.
Entries marked with an asterisk(*) are not specifically tested. They are either manufacturer's estimates based on performance of a particular elastomers compatibility with similar classes of chemicals, or they are performances available for some but not all compounds of a particular elastomer.
Note that when boiling temperature is indicated, the boiling temperature varies with the concentration of the media.
