| This information is provided only as a guide. Actual service life can only be determined by the user, evaluating the elastomer in actual service conditions. | |
| RATINGS CODE: | |
| A | Excellent: Long service may be expected with little or no affect on elastomer - suitable for continuous service. |
| B | Good: Good service may be expected, but elastomer will be affected by the chemical exposure - usually suitable for continuous or intermittent service. |
| C | Conditional: Fair service may be expected if chemical exposure is limited or infrequent. Not recommended for continuous, but may give some service if it is the only elastomer present. |
| X | Not Recommended. Insufficient Information: No data available at the time of publication to determine an accurate rating, but the elastomer is not expected to perform better than those listed. |
