Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

Introduction
Artichoke plants are herbaceous perennial plants, members of the Asteraceae family of plants, a group
that includes thistles, dandelions and sunflowers. They are short-lived perennials in warmer climates
but are normally grown as annuals in cooler regions. Artichokes are usually grown for the edible flower
buds, which are harvested before the flowers open. The unopened bud has overlapping rows of spine-
tipped green bracts enclosing the actual flower parts. At the base of the bud is the tender, flavourful
artichoke “heart,” which is the part that is cooked and eaten.
