Scope: WARNING — Persons using this part of ISO 16589 should be familiar with normal laboratory practice. Whilst this part of ISO 16589 does not purport to address all the safety problems, if any, associated with its application, attention is drawn to the need to employ sensible precautions while handling hot and cold fluids and equipment. It is the responsibility of the user of this part of ISO 16589 to establish appropriate safety and health practices and to ensure compliance with any national regulatory 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. This part of ISO 16589 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. NOTE ISO 16589 is complementary to ISO 6194, which covers seals incorporating elastomeric sealing elements.
