Below is a summary of known ISAF interpretations of (or informal opinions on) the International 14 class rules, excluding certain interpretations where the relevant rule has since been changed. Such interpretations are formally valid only for two years and (rather obviously!) apply to the rules as in existence at the time the interpretation was issued. They may also be applicable only to specific situations or to certain layouts/designs of the equipment in question.
The below is published for information only and no responsibility is accepted for its completeness, accuracy or relevance to a particular situation!
