Bibliography

Describes general test requirements for rotary shaft lip-type seals.

ISO6194 describes seals utilizing elastomeric sealing elements. They are considered suitable for use under low-pressure conditions (see ISO6194-1:2007, 6.1).

This part of ISO6194 specifies general test requirements for rotary shaft lip-type seals. The tests may be used for qualification purposes.

NOTE ISO6194 is complementary to ISO16589 which covers seals incorporating thermoplastic sealing elements.
