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.
