BS ISO 14743:2020 Pneumatic fluid power — Push-in connectors for thermoplastic tubes.
Plug one end of the test specimen and mount it in the apparatus with the plugged end unrestrained. Apply a pressure of 1,5 times MAWP to the test specimen and hold for 1 h at +80 °C.
9.4.4 Pass/fail criteria
The tube shall be disconnected from the connector. The connection under test shall not exhibit any
visual deformation or visual evidence of leakage after being subjected to the test.
9.5 Proof and burst pressure test (for PA tubing only)
The proof and burst pressure test is conducted with PA tubing, as specified in Annex A. and is intended to evaluate the ability of the connector to retain the tubing at a proof pressure of 1,5 times the rated pressure and at a minimum burst pressure of three times the rated pressure.
The test apparatus consists of a source of pressure and the necessary gauges and piping. The test fluid shall he water.
188.8.131.52 Plug one end of the test specimen and mount it in the apparatus with the plugged end unrestrained. Apply a proof pressure of 1,5 times the rated pressure to the test specimen and hold for a minimum of 30 s.
184.108.40.206 Increase pressure at a constant rate of 0,1 MPa/s to 0,2 MPa/s (1 bar/s to 2 hans) to reach the specified minimum burst pressure, i.e. three times the rated pressure. See Figure 8 for a typical pressure trace for the proof and burst pressure test.
9.5.4 Pass/fail criteria
220.127.116.11 The connection under test shall not exhibit any visual deformation or visual evidence of leakage after being sLibjected to the proof pressure for a minimum of 30 s.
18.104.22.168 The connection under test shall not fail after being subjected to the minimum burst pressure.
9.6 Connecting force test
Use a compression test machine and gauge to measure forces.
Mount the threaded end of the connector into a stationary fixture. Insert the tube into the connector by applying a compression load with the compression test machine set at a rate of 1 mm/s, and measure and record the maximum connecting force.
9.6.3 Pass/fail criteria
The force needed to connect shall not exceed the value given in Table 9 for the relevant tube OD.BS ISO 14743 pdf download.
