BS ISO 14743:2020 pdf free.Pneumatic fuid poweral Push-in onlastic tubes connec ctors for thermop.
BS ISO 14743 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. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

[-09 bar”I] to a working pressure of 1.6 MPa (16 bar) when used at temperatures between -20。C and +80 °C. 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. BS ISO 14743 pdf download.
