The word “may” is used in the text to express permissibility, e.g. as an alternative to the primary recommendation of the clause. The word “can” is used to express possibility, e.g. a consequence of an action or an event. All wording without use of these verbs is general commentary that provides a framework for useful understanding of the provisions of this standard. Paragraphs marked “NOTE” offer particular guidance in understanding or clarifying the associated requirement.
