ISO 14743-2020 pdf free download.Pneumatic fluid power — Push-in connectors for thermoplastic tubes.
This document 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.
This document 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.

4 Working conditions
Push-in connectors shall provide connections from —0,09 MPa 1—0,9 bar1)1 to a working pressure of 1,6 MPa (16 bar) when used at temperatures between —20 °C and +80 °C.
1) 1 bar = 0,1 MPa = 105 Pa; I MPa = 1 N/mm2

Iso 14743:2020(E)
The connector assembly shall meet the performance requirements given in Clause 9 with tubes specified in Annex A and Annex B.
When tubing with a lower rated pressure is used, the maximum working pressure of the tube and connector assembly shall be that of the tubing.
In road vehicles, it is necessary to exercise special care to ensure that these connectors are never used in an air braking system.ISO 14743 pdf download.
