The ANSI/BHMA industry standards exist to help identify the quality and durability of locksets via a series of operational and security tests. Following is a guide to how the standards are set. BHMA (Builders Hardware Manufacturers Association) is accredited by the American National Standards Institute (ANSI), a private non-profit organization that administers and coordinates the voluntary standardization to develop and maintain performance standards for builder's hardware. ANSI/BHMA standards set forth different product grades for door hardware products. These product grades are defined by progressive levels of performance benchmarks in each applicable standard.

Q. So what does this mean to me?

A.	Grade 3 Good: Residential Security
	Grade 2 Better: Light Commercial and Heavy Residential
	Grade 1 Best: Heavy Commercial Use
Each grade specifies minimum acceptable requirements for:
	Operation i.e.: key torque; cycles
	Security i.e.: pull strength, impact resistance finish
