ISO/TC 131/SC 7/WG 4 - Rotary shaft lip type seals

ISO 16589-2:2011 establishes the vocabulary for seals utilizing sealing elements manufactured from suitably formulated compounds, based on thermoplastic materials, such as polytetrafluoroethylene (PTFE) that are considered suitable for use under low-pressure conditions.

ISO 16589 specifies seals utilizing sealing elements manufactured from suitably formulated compounds based on thermoplastic materials, such as polytetrafluoroethylene (PTFE). They are considered suitable for use under low-pressure conditions. ISO 16589-1:2011 shows seal types and examples. It also specifies the nominal dimensions and tolerance of the seals, shafts and housings, as well as a dimensional identification code.

ISO 16589 specifies seals utilizing sealing elements manufactured from suitably formulated compounds based on thermoplastic materials, such as polytetrafluoroethylene (PTFE). They are considered suitable for use under low-pressure conditions. ISO 16589-5:2011 defines and classifies typical surface imperfections that could impair the function of the seals, and is intended as a convenience for purchasers and manufacturers in their discussions concerning the importance of these imperfections in different applications.

ISO 16589 specifies seals utilizing sealing elements manufactured from suitably formulated compounds, based on thermoplastic materials, such as polytetrafluoroethylene (PTFE). They are considered suitable for use under low-pressure conditions. ISO 16589-3:2011 gives users of lip-type seals guidance on the careful storage and handling and proper installation of rotary shaft lip-type seals; attention is drawn to the hazards involved and ways of avoiding them are pointed out.

ISO 16589 specifies seals utilizing sealing elements manufactured from suitably formulated compounds based on thermoplastic materials, such as polytetrafluoroethylene (PTFE). They are considered suitable for use under low-pressure conditions. ISO 16589-4:2011 specifies general performance tests which can be used for seal qualification purposes. Materials quality control, dynamic testing, and supplementary low-temperature testing requirements are covered.

ISO 6194 describes seals utilizing elastomeric sealing elements. They are considered suitable for use under low-pressure conditions. ISO 6194-4:2009 specifies general test requirements for rotary-shaft lip-type seals. The tests may be used for qualification purposes.

ISO 6194-5:2008 describes seals utilizing elastomeric sealing elements. They are normally considered suitable for use only at low pressures (see ISO 6194-1:2007, 6.1). ISO 6194-5:2008 defines and classifies typical surface imperfections that can impair the function of the seals and is intended as a convenience for purchasers and manufacturers in their discussions concerning the importance of these imperfections in different applications.

ISO 6194-1:2007 describes seals utilising elastomeric sealing elements. They are considered suitable for use under low-pressure conditions. ISO 6194-1:2007 shows seal types and examples. It also specifies the nominal dimensions and tolerances of the seals, shafts and housings, as well as a dimensional identification code.
