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.
