BS ISO 14743:2020 pdf download.Pneumatic fluid power – Push-in connectors for thermoplastic tubes.
In pneumatic fluid power systems, power is transmitted and controlled through air under pressure within a circuit.
Components are connected through their ports by means of connectors (fittings) and conductors.
BS ISO 14743:2020 specifies the general requirements and test methods for the design and performance of push-in connectors for use with thermoplastic tubes with outside diameters (OD) from 3 mm to 16 mm including dimensions in inches.
BS ISO 14743:2020 is intended to establish uniform methods of testing complete push-in connector assemblies as used in pneumatic fluid power applications. It is not applicable to air braking systems.
