The Builders Hardware Manufacturers Association (BHMA) released the latest version of the ANSI/BHMA 156.12 for Interconnected Locks and ANSI/BHMA 156.25 for Electrified Locking Devices, both approved by the American National Standards Institute (ANSI).

“These latest revisions are part of our ongoing role at BHMA to review products standards on a regular basis to continuously improve builders hardware standards,” said Michael Tierney, BHMA standards director. “As new technologies emerge, our products standards must evolve to meet the needs of both the public and of our industry.”

Changes to ANSI/BHMA 156.12 for Interconnected Locks include:

  • Updated test diagrams;
  • Updated reference standards;
  • A separate paragraph for lever deflection; and
  • Improvement in rose dent test diagrams.

Test frequency requirements have been added from the operational manual to the appendix.

Changes to ANSI/BHMA 156.25 for Electrified Locking Devices include updated reference standards; editorial updates; and clarification of sub-sections 6.4.6.1 through 6.4.6.4 Variable Ambiant Temperature Test.
