# ISO/IEC JTC 1/SC 28

ISO/IEC JTC 1/SC 28 Office equipment is a standardization subcommittee of the Joint Technical Committee ISO/IEC JTC 1 of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC), that develops and facilitates international standards, technical reports, and technical specifications within the field of office equipment and products, and systems composed of combinations of office equipment. The group's main focus lies within the area of printers and copiers. The international secretariat of ISO/IEC JTC 1/SC 28 is the Japanese Industrial Standards Committee (JISC) located in Japan.

## History

ISO/IEC JTC 1/SC 28 was established in 1989 at the JTC 1's second Plenary in Paris, France. The creation of the subcommittee came as a result of the proposal for a subcommittee on office equipment that was submitted by Japan, and accepted by JTC 1. At this plenary, the scope of ISO/IEC JTC 1/SC 28 was agreed upon, and has remained the scope of the subcommittee throughout its history. The initial secretariat of ISO/IEC JTC 1/SC 28 was the Swiss Association for Standardization (SNV), located in Switzerland. However, in 1997, the Brazilian National Standards Organization (ABNT), located in Brazil, became the new secretariat. In October 2002, the secretariat position was succeeded by JISC.

## Scope

The scope of ISO/IEC JTC 1/SC 28 is “Standardization of basic characteristics, test methods and other related items, excluding such interfaces as user system interfaces, communication interfaces and protocols, of office equipment and products such as Printers, Copying Equipments, Digital scanners, Facsimile equipment and systems composed of combinations of office equipment”.

## Structure

ISO/IEC JTC 1/SC 28 is made up of one advisory group, ISO/IEC JTC 1/SC 28/AG, and four active working groups (WGs), each of which carries out specific tasks in standards development within the field of office equipment. Working groups can be disbanded if the group's working area is no longer applicable to standardization needs, or established if new working areas arise. The focus of each working group is described in the group's terms of reference. Active working groups of ISO/IEC JTC 1/SC 28 are:
| Working Group | Working Area |
| ISO/IEC JTC 1/SC 28/WG 2 | Consumables |
| ISO/IEC JTC 1/SC 28/WG 3 | Productivity |
| ISO/IEC JTC 1/SC 28/WG 4 | Image quality assessment |
| ISO/IEC JTC 1/SC 28/WG 5 | Office colour |
