The results displayed in this data sheet were obtained on standard test specimens following standard test procedures. Comparisons with
results obtained on finished products, e.g. O-Rings, could lead to other results due to differences in geometry and manufacturing processes.
These other results do therefore not automatically contravene the data of this sheet. The evaluation of parts prior to their use in order to
ensure their suitability for the intended application is subject to the end user's responsibility.
