Overview

EN ISO 4080:2024 - Rubber and plastics hoses and tubing, and their assemblies - Determination of permeability to gas (ISO 4080:2024) is the fifth-edition CEN-endorsed standard for measuring gas permeability through rubber and plastic hoses, tubing and their assembled fittings. Approved June 2024 and superseding EN ISO 4080:2009, the document defines three standardized test methods to quantify the volume of test gas diffusing through hose/tubing walls, the hose–fitting interface, or the complete assembly including end fittings.

Key topics and technical requirements

• Three test methods
  • Method 1 - measures permeability of the complete hose or tubing wall (excluding end fittings). Typical test piece: 1 m ± 0.01 m exposed under the gas-collecting trough.
  • Method 2 - measures permeability specifically at the hose-to-fitting interface (textile-reinforced hose with unpricked cover; 1 m ± 0.01 m between fittings).
  • Method 3 - measures permeability of the complete assembly including end fittings (minimum test length 0.5 m ±1 %; 1 m may be used for direct comparison across methods).
• Apparatus and instrumentation
  • Gas supply with pressure regulator and safety excess-flow shutoff.
  • Calibrated pressure gauge/transducer (test pressure targeted between 15 % and 85 % of full-scale).
  • Water bath for temperature control and gas-collecting apparatus (measuring cylinders, troughs/funnels) as illustrated in the standard.
• Test conditions and procedure
  • Specified test temperature, test gas selection, and test pressure requirements.
  • Preparation and conditioning of test pieces in accordance with referenced methods.
  • Clear expression of results and required test-report contents.
• Supporting material
  • Definitions, terms (permeability, end fitting), and informative annexes offering guidance on permeability interpretation, method selection and saturated vapour pressure.

Applications and practical value

• Use this standard to:
  • Assess and compare gas permeability performance of hoses, tubing and assemblies for gas-handling applications.
  • Validate compatibility of end fittings and sealing methods where leak-tightness and permeation control are critical.
  • Support product specification, quality control, type approval and supplier evaluation for gas delivery systems.
• Typical sectors: manufacturers of rubber/plastic hoses and tubing, independent testing laboratories, OEMs and procurement teams specifying components for gas applications (industrial gas transfer, fuel/gasoline systems, medical gas delivery, and other gas service uses).

Who should use this standard

• Hose and tubing manufacturers, test laboratories, product designers, quality assurance and compliance teams, and technical procurement specialists working with gas applications requiring quantified permeability data.

Related standards

• ISO 8330 - Vocabulary for rubber and plastics hoses and assemblies (referenced for terms).
• ISO 23529 - General procedures for preparing and conditioning rubber test pieces.
• EN ISO 4080:2009 - previous edition (now superseded).

permeability
property of a material of transmitting gases and liquids by passage through one surface and out at another
surface by diffusion and sorption processes
Note 1 to entry: Not to confuse with “porosity”.

Note 2 to entry: The property of a permeability involves the diffusion of molecules, called the permeant, through
a membrane or interface. The permeability property works through diffusion< the permeant will move from high
concentration to low concentration across the interface.
