Standards Interpretations

A request for interpretation may be either 'official' or 'unofficial' (personal). An official interpretation is defined as a written explanation of the meaning of a specific provision of a standard or guideline, as determined by an existing cognizant Project Committee (PC) or an Interpretation Committee (IC), in response to a written request. An unofficial or personal interpretation is a written explanation of the meaning of a specific provision of a standard or guideline, as determined by the Manager of Technical Services, the past or current Chair of the cognizant PC, or the Manager of Standards (MOS), in response to a written request.
