Who this document matters to

A procedural challenge to the sample collection procedure is one of the most common lines of defence in doping cases, and its basis is this very text: from the manner of notification and chaperoning of the athlete through to the chain of custody of the sample. The rules on whereabouts information are also set out in detail in this document.

Each case is governed by the edition of this Standard that was in force at the time of the event; for that reason, previous editions are kept available on this page. The official text is published in English and French and, in the event of any conflict, the English text prevails.
