Crude Approval Grids (CAGs) define a set of conditions for an assay. On the basis of these conditions, an approval result is determined to indicate the level to which this crude satisfies the approval criteria. On the basis of CAGs, you can display crude approval results for individual assays. For example you can specify that a crude should be rejected if the sulfur level of a particular cut is above a certain percentage, and a warning given if the sulfur level is high but not high enough to reject.

The CAGs page shows the CAG cases that are available to you in Assay. The list can be filtered to find specific CAGs. These cases may have been created by you, or may have been created by other Assay users and shared. Several icons are available for working with shared cases:
