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 document 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 and IEC 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

This document was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 28, Office equipment.
This fourth edition cancels and replaces the third edition (ISO/IEC 24711:2015), which has been
technically revised.
The main changes compared to the previous edition are as follows:
— printer setting was corrected from duplex to simplex mode in Clause 4.1;
— the status of Annex E was changed from informative to normative to have consistency with
ISO/IEC 19798;
— ISO/IEC 29142-1 has been added to the Bibliography;
— editorial changes were applied.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Introduction
The purpose of this document is to provide a process for determining the ink cartridge yield for a
given colour inkjet print system (i.e. integrated ink cartridges and ink cartridges without integrated
printheads) using a standard consumer type test page suite. In the case where a cartridge set can be
used in multiple printer models, only one yield test needs to be performed as long as the difference
between printer models does not impact yield.
NOTE A cartridge supplier can choose to use more than one market identifier for a single physical cartridge.
In this case, only one yield test is required as long as there are no differences in the cartridges other than market
identifiers.
This document prescribes the following:
— the test method that manufacturers, test laboratories, etc. use to determine ink cartridge yield;
— the method for determination of declared yield values from the test results;
— the appropriate method of describing the yield of cartridges in documentation supplied to the
consumer by the manufacturer.
The cartridge yield is determined by an end-of-life judgement, or signalled with either of two
phenomena: fade, caused by depletion of ink in the cartridge, or automatic printing stop, caused by an
ink out detection function. It is envisioned that one of the uses of this document is for the calculation
of cost per page (CPP). While this document measures a portion of this cost, it is not used as the sole
component of CPP calculation. Additional factors are considered for CPP calculations. It is beyond the
scope of this document to provide a methodology for calculation of CPP.

Information technology — Office equipment — Method for
the determination of ink cartridge yield for colour inkjet
printers and multi-function devices that contain printer
components
1 Scope
The scope of this document is limited to the evaluation of ink cartridge page yield for ink-containing
cartridges (i.e. integrated ink cartridges and ink cartridges without integrated printheads) for colour
inkjet print systems. This document can also be applied to the printer component of any multifunctional
device that has a digital input printing path, including multi-function devices that contain inkjet printer
components. Both liquid and solid ink products can be tested using this document.
This document is only intended for the measurement of ink cartridge page yield when printing on plain
paper. No other claims can be made from this testing regarding quality, reliability, etc.
This document can be used to measure the yield of any cartridge that is used in a significant amount
during the printing of the test page suite defined in ISO/IEC 24712.
This document is not for use with printers whose minimum printable size is equal to or greater than A3
or for printers designed or configured to print photos (for example, maximum printable size less than
A4 or a printe
