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).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www .iso

This document was prepared by Technical Committee ISO/TC 119, Powder metallurgy, Subcommittee
SC 3 Sampling and testing methods for sintered metal materials (excluding hardmetals).
This third edition cancels and replaces the second edition (ISO 4022:1987), of which it constitutes a
minor revision with the following changes:
— Clause 3 and Clause 4 order reversed, and Clause 3 split into 3.1 and 3.2;
— 3.1.3, 3.1.4, 3.1.5, 3.1.13 and 3.1.14 editorially revised;
— Clause 3: Terminological entries ‘length’ and ‘dynamic viscosity’ removed;
— 6.1.1 and 6.1.2, Figures 1 and 2 and keys editorially revised;
— 7.1.2, first Formula removed and Formula (2) corrected, “l” changed to “1”;
— 8.3, Formula (12) corrected, “ρ” changed to “ϱ”.

INTERNATIONAL STANDARD ISO 4022:2018(E)
Permeable sintered metal materials — Determination of
fluid permeability
1 Scope
This document specifies a method for the determination of the fluid permeability of permeable sintered
metal materials in which the porosity is deliberately continuous or interconnecting, testing being
carried out under such conditions that the fluid permeability can be expressed in terms of viscous and
inertia permeability coefficients (see Annex A).
This document does not apply to very long hollow cylindrical test pieces of small diameter, in which the
pressure drop of the fluid in passing along the bore of the cylinder might not be negligible compared
with the pressure drop of the fluid passing through the wall thickness (see
