The Builders Hardware Manufacturers Association (BHMA®) has announced the publication of revisions to five product standards, all of which have been approved by the American National Standards Institute (ANSI). Doing so, the association says, reinforces its commitment to public safety.

“BHMA reviews each ANSI/BHMA standard at least once every five years to ensure that our standards continue to meet the ever-changing needs of both the public and our industry,” said BHMA Standards Director Michael Tierney. “This work is essential for maintaining alignment with modern quality requirements in our industry.”
