The ISO Central Secretariat has information only on standards developed by ISO. If you are looking for a standard developed by another organization (a standard with a reference number which does not begin with "ISO"), please contact the relevant organization for more information about it.

If you do not know how to identify or contact the organization concerned, you have a few options for getting help:

• You can contact the ISO member in your country.

  List of ISO members worldwide

• If there is an ISONET (ISO Information Network) member in your country, their information service is responsible for alll standards information enquiries in their country. Many can provide information about international, regional, foreign national standards and their own national standards and regulations. The ISONET Directory gives contact information for all ISONET members and lists the services they can provide.

• The standards organization in question may be a member of WSSN (World Standards Services Network). WSSN acts as a gateway to the Web sites of international and regional standardizing bodies, as well as to the sites of the national members of ISO and IEC (International Electrotechnical Commission). A site search is available.
