Описание (английский):

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.

Overview

SIST ISO 14743:2021 - "Pneumatic fluid power - Push-in connectors for thermoplastic tubes" defines uniform design, dimensional and test requirements for push-in (push-to-connect) fittings used with thermoplastic tubes. The standard covers connector assemblies for tube outside diameters (OD) from 3 mm up to 16 mm (including common inch equivalents) and establishes performance and verification methods for pneumatic fluid power applications. It is explicitly not applicable to air braking systems.

Key topics and technical requirements

Scope & applicability: Connectors for thermoplastic tubing OD 3 mm to 16 mm (including inch sizes); intended for pneumatic fluid power systems.

Working conditions: Connector assemblies are required to perform between –0.09 MPa and 1.6 MPa (–0.9 bar to 16 bar) at temperatures from –20 °C to +80 °C. When tubing has a lower rated pressure, the assembly’s max working pressure is that of the tubing.

Dimensions & design: Standardized maximum tube insertion depths, dimensional tables, and optional contours; hexagon tolerances per ISO 4759‑1 (Grade C). Thread interfaces reference ISO 16030, ISO 7‑1 and relevant ANSI/ASME thread standards for inch/NPT/UNF.

Marking & designation: Requirements for marking, designation and identification statements to reference the standard.

Performance tests (Clause 9) - uniform test methods to assess complete assemblies, including:

Tensile test
Pressure at maximum temperature (for PA tubing)
Proof and burst pressure tests (for PA tubing)
Connecting and disconnecting force tests
Leakage test (pre-disconnect)
Cyclic endurance (impulse) test with vibration (for PA tubing)

Test samples & criteria: Procedures and pass/fail criteria are specified for repeatable laboratory verification; normative annexes provide example PA and PU tubes for testing.

Practical applications and who uses this standard

SIST ISO 14743:2021 is essential for:

Manufacturers of push-in connectors and fittings - design, dimensioning and conformity testing.

Pneumatic system designers and OEMs - selecting certified connectors compatible with thermoplastic tubing.

Quality & test laboratories - performing standardized tensile, pressure, leakage and endurance tests.

Procurement and compliance teams - verifying supplier claims and ensuring interchangeability across international markets.

Maintenance and asset engineers - understanding performance limits and test-backed reliability for replacements.
