Rationale

This document was revised as part of the 5-year review process. There are minor editorial updates in Section 3 to be consistent with parts of speech and changes to sections 2.2, 2.3, 2.4 and 6.2.1 to be consistent with changes to Policy P-10. As this standard is overdue and needs to be balloted before the end of this year to avoid withdrawal, this ballot is for reapproval and editorial changes only. Once renewed, future changes will be made in subsequent balloting.
