New Standards

ISO 15524:2011: Pneumatic fluid power – Cylinders – Single-rod short-stroke cylinders, 1 000 kPa (10 bar) series, bores from 20 mm to 100 mm. This International Standard establishes a metric series of single-rod pneumatic short-stroke cylinders with bores from 20 mm to 100 mm (inclusive) for use of at maximum working pressure of 1 000 kPa [10 bar1)] with and without magnetic function. They are not equipped with adjustable cushioning, so their application is restricted to those systems where adjustable cushioning is not required.
Benefits:
This dimensional interchangeability standard benefits users by allowing them to purchase single-rod short-stroke pneumatic cylinders from multiple suppliers, and manufacturers of these valves to benefit from economies of scale afforded by the standard.

ISO 16589-3:2011: Rotary shaft lip-type seals incorporating thermoplastic sealing elements — Part 3: Storage, handling and installation (second edition). 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 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.
Benefits:
ISO 16589-3 can help improve seal performance by providing guidance on the correct storage, handling and proper installation of rotary shaft lip type seals incorporating thermoplastic sealing elements.
Price per copy: $66.00 (NFPA members), $83.00 (list)

ISO 16589-1:2011: Rotary shaft lip-type seals incorporating thermoplastic sealing elements — Part 1: Nominal dimensions and tolerances (second edition). 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 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.
Benefits:
ISO 16589-1 benefits manufacturers of rotary shaft lip type seals incorporating thermoplastic sealing elements by establishing dimensions for these seals. The standard benefits manufacturers of components in which these seals are used (e.g. pumps and motors) by specifying the dimensional limits of shafts and housings. Proper use of seals in housings that both conform to ISO 16589-1 should result in excellent sealing performance.
