ISO deliverables

The different types of ISO publications

While ISO is best known for its International Standards, it has other deliverables. Below are the types of deliverables developed by ISO.

International Standards

An International Standard provides rules, guidelines or characteristics for activities or for their results, aimed at achieving the optimum degree of order in a given context. It can take many forms. Apart from product standards, other examples include: test methods, codes of practice, guideline standards and management systems standards.

Technical Specification

A Technical Specification addresses work still under technical development, or where it is believed that there will be a future, but not immediate, possibility of agreement on an International Standard. A Technical Specification is published for immediate use, but it also provides a means to obtain feedback. The aim is that it will eventually be transformed and republished as an International Standard.

Technical Report

A Technical Report contains information of a different kind from that of the previous two publications. It may include data obtained from a survey, for example, or from an informative report, or information of the perceived “state of the art”.

Publicly Available Specification

A Publicly Available Specification is published to respond to an urgent market need, representing either the consensus of the experts within a working group, or a consensus in an organization external to ISO. As with Technical Specifications, Publicly Available Specifications are published for immediate use and also serve as a means to obtain feedback for an eventual transformation into an International Standard. Publicly Available Specifications have a maximum life of six years, after which they can be transformed into an International Standard or withdrawn.

International Workshop Agreements

In order to respond to urgent market requirements, International Workshop Agreements are prepared through a workshop mechanism outside of ISO committee structures, following a procedure that ensures the broadest range of relevant interested parties worldwide have the opportunity to participate, and are approved by consensus amongst the individual participants in the workshops. If there is an existing ISO committee whose scope covers the topic, the published International Workshop Agreement is automatically allocated to this committee for maintenance. An International Workshop Agreement is reviewed three years after its publication and can be further processed to become a Publicly Available Specification, a Technical Specification or an International Standard, according to the market requirement. An International Workshop Agreement can exist for a maximum of six years, following which it is either withdrawn or converted into another ISO document.

Guides are just that. They help readers understand more about the main areas where standards add value. Some Guides talk about how, and why, ISO standards can make it work better, safer, and more efficiently. Full list of Guides available in the ISO Catalogue.

Optimized Deliverables project
The project aims at optimizing our set of deliverables and ensuring their best use to meet longstanding, emergent and urgent market needs.
This brochure offers delegates and experts a quick reference to the ISO system and its processes.
