FM Class vs FM Approval: Which statement correctly contrasts them?

• A. Class indicates performance capability, while Approval indicates a tested assembly meeting FM criteria.
• B. Approval indicates performance capability; Class is a generic label.
• C. FM Class refers to installation quality, FM Approval to cost.
• D. Both terms mean the same thing.

Answer: (A)

FM Class and FM Approval operate at different certification levels. A product Class shows the inherent performance capability of a product family—it indicates that the type of product has been evaluated and has defined performance characteristics under FM criteria. FM Approval, in contrast, is about a specific product in a specific installation that has been tested and certified to meet FM criteria for a particular use or system. In practice, you’d rely on Approval when you need assurance that a particular assembly will perform as tested, while Class gives you a general sense of what that product category can achieve. That’s why the correct distinction is that Class indicates performance capability, while Approval indicates a tested assembly meeting FM criteria. The other statements blur or invert this relationship.
