The International Organization for Standardization (Organisation internationale de normalisation), widely known as ISO, is an international standard-setting body composed of representatives from various national standards organizations. Founded on 23 February 1947, the organization promulgates world-wide industrial and commercial standards. It is headquartered in Geneva, Switzerland.^[1]

While ISO defines itself as a non-governmental organization, its ability to set standards that often become law, either through treaties or national standards, makes it more powerful than most NGOs. In practice, ISO acts as a consortium with strong links to governments.^[1]

Name and abbreviation

The organization's logos in its two official languages, English and French, include the letters ISO, and it is usually referred to by these letters. ISO is not, however, an acronym or initialism for the organization's full name in either official language. Rather, the organization adopted ISO based on the Greek word ἴσος (isos), which means equal. Recognizing that the organization’s initials would be different in different languages, the organization's founders chose ISO as the universal short form of its name. This, in itself, reflects the aim of the organization: to equalize and standardize across cultures.^[2][3]

International Standards and other publications

ISO's main products are the International Standards. ISO also publishes Technical Reports, Technical Specifications, Publicly Available Specifications, Technical Corrigenda, and Guides.^[4]

International Standards are identified in the format ISO[/IEC][/ASTM] [IS] nnnnn[:yyyy] Title, where nnnnn is the number of the standard , yyyy is the year published, and Title describes the subject. IEC is included if the standard results from the work of JTC1 (the Joint Technical Committee). ASTM is used for standards developed in cooperation with ASTM International. The date and IS are not used for an incomplete or unpublished standard, and may under some circumstances be left off the title of a published work.

Technical Reports can be issued when "a technical committee or subcommittee has collected data of a different kind from that which is normally published as an International Standard",^[4] such as references and explanations. The naming conventions for these are the same as for standards, except TR prepended instead IS in the report's name. Examples:

• ISO/IEC TR 17799:2000 Code of Practice for Information Security Management
• ISO/TR 19033:2000 Technical product documentation — Metadata for construction documentation

Technical Specifications can be produced when "the subject in question is still under development or where for any other reason there is the future but not immediate possibility of an agreement to publish an International Standard". Publicly Available Specifications may be "an intermediate specification, published prior to the development of a full International Standard, or, in IEC may be a 'dual logo' publication published in collaboration with an external organization".^[4] Both are named by convention similar to Technical Reports, for example:

• ISO/TS 16952-1:2006 Technical product documentation — Reference designation system — Part 1: General application rules
• ISO/PAS 11154:2006 Road vehicles — Roof load carriers

ISO sometimes issues a Technical Corrigendum. These are amendments to existing standards because of minor technical flaws, usability improvements, or to extend applicability in a limited way. Generally, these are issued with the expectation that the affected standard will be updated or withdrawn at its next scheduled review.^[4]

ISO Guides are meta-standards covering "matters related to international standardization".^[4] They are named in the format "ISO[/IEC] Guide N:yyyy: Title", for example:

• ISO/IEC Guide 2:2004 Standardization and related activities — General vocabulary
• ISO/IEC Guide 65:1996 General requirements for bodies operating product certification

ISO document copyright

ISO documents are copyrighted and ISO charges for copies of most. ISO does not, however, charge for most draft copies of documents in electronic format. Although useful, care must be taken using these drafts as there is the possibility of substantial change before it becomes finalized as a standard. Some standards by ISO and its official U.S. representative (and the International Electrotechnical Commission's via the U.S. National Committee) are made freely available.^[5][6]

Members

ISO has 157 national members,^[7] out of the 195 total countries in the world.

ISO has three membership categories:

• Member bodies are national bodies that are considered to be the most representative standards body in each country. These are the only members of ISO that have voting rights.
• Correspondent members are countries that do not have their own standards organization. These members are informed about ISO's work, but do not participate in standards promulgation.
• Subscriber members are countries with small economies. They pay reduced membership fees, but can follow the development of standards.

Participating members are called "P" members as opposed to observing members which are called "O" members.

Products named after ISO

The fact that many of the ISO-created standards are ubiquitous has led, on occasion, to common usage of "ISO" to describe the actual product that conforms to a standard. Some examples of this are:

• CD images end in the file extension "ISO" to signify that they are using the ISO 9660 standard filesystem as opposed to another file system - hence CD images are commonly referred to as "ISOs". Virtually all computers with CD-ROM drives can read CDs that use this standard. Some DVD-ROMs also use ISO 9660 filesystems.
• Photographic film's sensitivity to light, its "film speed," is described by ISO 5800:1987. Hence, the film's speed is often referred to as its "ISO number."

ISO/IEC Joint Technical Committee 1

To deal with the consequences of substantial overlap in areas of standardization and work related to information technology, ISO and IEC formed a Joint Technical Committee known as the ISO/IEC JTC1. It was the first such committee, and to date remains the only one.

Its official mandate is to develop, maintain, promote and facilitate IT standards required by global markets meeting business and user requirements concerning

• the design and development of IT systems and tools
• the performance and quality of IT products and systems
• the security of IT systems and information
• the portability of application programs
• the interoperability of IT products and systems
• the unified tools and environments
• the harmonized IT vocabulary, and
• the user-friendly and ergonomically-designed user interfaces.

There are currently 18 sub-committees:

• SC 02 - Coded Character Sets
• SC 06 - Telecommunications and Information Exchange Between Systems
• SC 07 - Software and System Engineering
• SC 17 - Cards and Personal Identification
• SC 22 - Programming Languages, their Environments and Systems Software Interfaces
• SC 23 - Removable Digital Storage Media Utilizing Optical and/or Magnetic Recording * Technology for Digital
• SC 24 - Computer Graphics and Image Processing
• SC 25 - Interconnection of Information Technology Equipment
• SC 27 - IT Security Techniques
• SC 28 - Office Equipment
• SC 29 - Coding of Audio, Picture, and Multimedia and Hypermedia Information
• SC 31 - Automatic Identification and Data Capture Techniques
• SC 32 - Data Management and Interchange
• SC 34 - Document Description and Processing Languages
• SC 35 - User Interfaces
• SC 36 - Information Technology for Learning, Education, and Training
• SC 37 - Biometrics

Membership in ISO/IEC JTC1 is restricted in much the same way as membership in either of the two parent organizations. A member can be either participating (P) or observing (O) and the difference is mainly the ability to vote on proposed standards and other products. There is no requirement for any member body to maintain either (or any) status on all of the sub-committees. Although rare, sub-committees can be created to deal with new situations (SC 37 was approved in 2002) or disbanded if the area of work is no longer relevant.

IWA document

Like ISO/TS, International Workshop Agreement (IWA) is another armoury of ISO for providing rapid response to requirements for standardization in areas where the technical structures and expertise are not currently in place. The utility harmonizes technical urgency industrial wide.
