We emphasize that this tabulation should be used as a guide only.
It is based primarily on laboratory and service tests, but does not take into account all variables that can be encountered in actual use. Therefore, it is always advisable to test the material
under actual service conditions before specification. If this is not practical, tests should be devised that simulate service conditions as closely as possible.
