Many ANSI/BHMA standards define different product grades for a particular hardware item. These product grades (grade 1, 2, or 3 -- with grade 1 being the highest) are:
- Defined by progressive levels of performance benchmarks in each applicable ANSI/BHMA standard.
- Also ascertained by looking at its BHMA® product number.
- A way of defining other important classification information, such as the predominant material used, product category, and function of a specific hardware item.
