Foreword

ISO (the International Organization for Standardization) and IEC (the International Electrotechnical

Commission) form the specialized system for worldwide standardization. National bodies that are

members of ISO or IEC participate in the development of International Standards through technical

committees established by the respective organization to deal with particular fields of technical

activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international

organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the

work.

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

Introduction

The purpose of this document is to define the framework for characterizing ink and toner cartridges

used in printing devices that have a digital input printing path, including multi-function devices.

This document defines terms, symbols, and notations used throughout the ISO/IEC 29142 series to

characterize such ink and toner cartridges.

Customer information related to ink and toner cartridges is not consistent in the global marketplace.

Cartridge manufacturers, including original, non-original manufacturers, refillers, and remanufacturers,

have each communicated expressions of cartridge characteristics.

The ISO/IEC 29142 series is provided to aid transparency between manufacturers, suppliers and

their customers regarding selected cartridge characteristics. The selected cartridge characteristics

do not allow an exhaustive cartridge characterization. Where applicable, cartridge attributes and the

associated characterization tests are used consistently with both ink and toner cartridge technologies.

The selected cartridge attributes are defined for all cartridges, regardless of manufacturing

methodology.

4 Requirements

The framework explained in this document shall not be used directly for comparison of products.

For a comparison using test-method standards compliant with the framework of this document, the

minimum requirement is that the conditions for measuring parameters, as well as the entire test

conditions explained in such compliant standards are required to be in agreement.

5 Structure of the ISO/IEC 29142 series
5.1 Data reporting

This document establishes the product and package labelling requirements, and related reporting

requirements for toner and ink cartridges used in printing devices that have a digital input printing

path, including multi-function devices.

Cartridge-characterization tests standardized or specified in the ISO/IEC 29142 series to be compliant

with this document, and environmental standards compliant with ISO/IEC 29142-3, shall adhere to

the labelling, notification and reporting specifications in ISO/IEC 29142-2. For conformance with the

ISO/IEC 29142 series, according to ISO/IEC 29142-2, four levels of labelling, notification and reporting

are established:
— a cartridge label,
— a cartridge notification,
— a customer report,
— a cartridge-attribute test report.

Customer and cartridge-attribute test reports from ink and toner cartridge-attribute characterization

testing shall include results from the test performed directly on each printing system that shall be

claimed in the cartridge reporting.

The provisions for traceability between these notification and reporting levels and the related

cartridges are specified.

Processes applied after cartridge end-of-life can include recycling cartridges for new cartridges and

other new uses, such as in the manufacture of non-cartridge products, refill of car

Foreword

ISO (the International Organization for Standardization) and IEC (the International Electrotechnical

Commission) form the specialized system for worldwide standardization. National bodies that are

members of ISO or IEC participate in the development of International Standards through technical

committees established by the respective organization to deal with particular fields of technical

activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international

organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the

work.

Introduction

The purpose of this document is to define the framework for characterizing ink and toner cartridges

used in printing devices that have a digital input printing path, including multi-function devices.

This document defines terms, symbols, and notations used throughout the ISO/IEC 29142 series to

characterize such ink and toner cartridges.

Customer information related to ink and toner cartridges is not consistent in the global marketplace.

Cartridge manufacturers, including original, non-original manufacturers, refillers, and remanufacturers,

have each communicated expressions of cartridge characteristics.

The ISO/IEC 29142 series is provided to aid transparency between manufacturers, suppliers and

their customers regarding selected cartridge characteristics. The selected cartridge characteristics

do not allow an exhaustive cartridge characterization. Where applicable, cartridge attributes and the

associated characterization tests are used consistently with both ink and toner cartridge technologies.

The selected cartridge attributes are defined for all cartridges, regardless of manufacturing

methodology.

4 Requirements

The framework explained in this document shall not be used directly for comparison of products.

For a comparison using test-method standards compliant with the framework of this document, the

minimum requirement is that the conditions for measuring parameters, as well as the entire test

conditions explained in such compliant standards are required to be in agreement.

5 Structure of the ISO/IEC 29142 series
5.1 Data reporting

This document establishes the product and package labelling requirements, and related reporting

requirements for toner and ink cartridges used in printing devices that have a digital input printing

path, including multi-function devices.

Cartridge-characterization tests standardized or specified in the ISO/IEC 29142 series to be compliant

with this document, and environmental standards compliant with ISO/IEC 29142-3, shall adhere to

the labelling, notification and reporting specifications in ISO/IEC 29142-2. For conformance with the

ISO/IEC 29142 series, according to ISO/IEC 29142-2, four levels of labelling, notification and reporting

are established:
— a cartridge label,
— a cartridge notification,
— a customer report,
— a cartridge-attribute test report.

Customer and cartridge-attribute test reports from ink and toner cartridge-attribute characterization

testing shall include results from the test performed directly on each printing system that shall be

claimed in the cartridge reporting.

The provisions for traceability between these notification and reporting levels and the related

cartridges are specified.

Processes applied after cartridge end-of-life can include recycling cartridges for new cartridg
