International Organization for Standardization (ISO) Irrigation Standards
Current Listing of International Irrigation Standards(September 2000) The following listing of irrigation standards are as developed and promulgated by the International Organization for Standardization (ISO). ISO is an international agency for standardization, headquartered in Geneva, Switzerland. Members of ISO are the national standards bodies of about 90 countries. The United States representative is the American National Standards Institute (ANSI). The objectives of ISO are to advance worldwide standardization; to facilitate international exchange of goods and services; and to promote cooperation in intellectual, scientific, technological, and economic activity.
ISO is comprised of more than 2,000 technical committees, subcommittees, and working groups. Individual countries participate in the development of these standards as members of technical advisory groups with related subcommittees. In this case, the designated subcommittee is noted as ISO/TC23/SC18 (irrigation and drainage standards). Recently the countries most active in SC18 have been Israel, France, the United States, Canada, Spain, and Italy. Other countries that have participated in the past are Belgium, the Peoples Republic of China, Denmark, Germany, Hungary, and the United Kingdom. The secretariat and chair of SC18 are held by Israel.
The Irrigation Association (IA) is officially accredited by ANSI to review proposed standards and advise ANSI on the appropriate voting action. The Center for Irrigation Technology (CIT) in turn is contracted to the IA to handle all administrative matters and represent the IA on SC18.
