ISO/TR 16194:2017 provides general procedures for assessing the reliability of pneumatic fluid power components using accelerated life testing and the method for reporting the results. These procedures apply to directional control valves, cylinders with piston rods, pressure regulators, and accessory devices ? the same components covered by the ISO 19973 series of standards. ISO/TR 16194:2017 does not provide specific procedures for accelerated life testing of components. Instead, it explains the variability among methods and provides guidelines for developing an accelerated test method. The methods specified in this document apply to the first failure, without repairs.

ISO 27996:2009 is applicable to the general requirements for data recording procedures, packaging, and storing of elastomeric seals and seal assemblies which include an elastomeric element prior to the seal being assembled into hardware components. The requirements for packaging are an integral part of the controlled storage procedure and provide a means of positive product identity from the time of manufacture to the time of assembly into a component. ISO 27996:2009 does not establish limitations or storage times for assembled components nor the operating life of these components. The information contained in ISO 27996:2009 is intended for use by those organizations that do not have specific requirements or recommendations already in place for the control of elastomeric seals and seal assemblies. ISO 27996:2009 can be specified in control, storage and procurement documents. However, when the requirements of ISO 27996:2009 are in conflict with the customer's requirements or specifications, the requirements of the customer's detailed specifications take precedence.

ISO 16031-2:2003 specifies the inside diameters, cross-sections, tolerances and size identification codes for inch O-rings used in aerospace fluid systems intended for use in non-hydraulic systems. ISO 16031-2:2003 is applicable, provided that suitable tooling is available, to O-rings made from all other elastomeric materials other than nitrile and ethylene propylene materials, for which ISO 16031-1 specifies the dimensions. Specifications for O-rings with an inside diameter up to 12,7 mm have been taken from ISO 16031-1, because the same tolerances are applicable to the O-rings in ISO 16031-2:2003.

ISO 16031-1 specifies the inside diameters, cross-sections, tolerances and size identification codes for inch O-rings used in aerospace fluid systems. The dimensions and high precision tolerances specified in ISO 16031-1 are suitable for nitrile and ethylene propylene materials intended for use in high pressure hydraulic fluid systems provided that suitable tooling be available.

Specifies the requirements. It is essential that these rings be individually enclosed in sealed envelopes or in pockets in a multiple envelope provided that they can be removed without affecting the sealing of the remainder of the components in the package. The marking of package shall include the part number, material specification number, quarter and year of cure, compound number, acceptance batch number and manufacturer's identity.
