Application Summary AI generated

This standard specifies the dimensions, performance requirements, and test methods for diagnostic couplings used in hydraulic fluid power systems that are not intended to be connected or disconnected under pressure. It is applied in industrial machinery, mobile equipment, and hydraulic testing contexts where technicians need to safely attach pressure measurement or diagnostic equipment to a hydraulic system after it has been depressurized. The standard ensures interchangeability and reliable sealing of these couplings across different manufacturers and applications.
