Rubber and plastics hoses and tubing, and their assemblies - Determination of permeability to gas (ISO 4080:2024)
This document specifies three methods to determine the permeability to gas by measuring the volume of gas diffusing through a rubber or plastics hose or length of tubing used for gas applications in a specified time.
— Method 1 is for determining the permeability of the complete hose wall or length of tubing wall, excluding end fittings, to the test gas.
— Method 2 is for determining the permeability at the hose and fitting interface to the test gas.
— Method 3 is for precisely determining the permeability of the complete hose or length of tubing, including end fittings.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).

Rubber and plastics hoses and tubing, and their
assemblies — Determination of permeability to gas
WARNING — Persons using this document should be familiar with normal laboratory practice.
This document does not purport to address all of the safety problems, if any, associated with its
use. It is the responsibility of the user to establish appropriate safety and health practices.
1 Scope
This document specifies three methods for the determination of the volume of gas diffusing through a
rubber or plastics hose or length of tubing used for gas applications in a specified time.
Method 1:
For determining the volume of gas diffusing through the complete hose or length of tubing,
excluding end fittings in a specified time. This method is suitable for textile reinforced hose
with either pricked cover or textile cover or both, although this method is not suitable for
textile reinforced hose with unpricked cover. The permeability is calculated with respect to
the length of the hose or tubing and to the surface area of the hose lining or the tubing.
Method 2:
For determining the volume of gas diffusing at the hose and fitting interface. This method is
used when determining the permeability characteristics of textile reinforced hoses with an
unpricked cover, when the gas usually issues from the textile reinforcement at the cut ends.
The permeability is calculated with respect to the length of the hose and to the surface area of
the hose lining.
Method 3:
For precisely determining the volume of gas diffusing through the complete hose or length
of tubing including end fittings in a specified time. This method is not suitable for textile
reinforced hose with unpricked cover. The permeability is calculated with respect to the length
of the hose or tubing and to the surface area of the hose lining or the tubing.
NOTE 1 Guidance on test methods are provided in Annex C, Table C.1.
NOTE 2 Explanation of permeability is provided in Annex A, where the concept of trapped air and permeation
is explained in Figure A.1.
