Corrosion resistance data given in this section are based on laboratory tests conducted by the manufacturers of the materials covered and are indicative only of the conditions under which the tests were made. The testing was done using non-stressed single strips of material being immersed in the chemical for a period of time. The information may be considered as a basis for suitability, but not as a guarantee. It is recommended that the materials should be tested in actual service to determine suitability for a particular purpose. When selecting elastomeric seals for specific applications, there are a number of important selection criteria including the anticipated service conditions, the design and inspection requirements for the particular application, and material specification and traceability.
