On February 7, 2019, the Business Institutional Furniture Manufacturers Association (BIFMA) released a new version of its storage unit standard BIFMA X5.9. The updated version replaces the previous 2012 version and is approved by the American National Standards Institute (ANSI).
BIFMA X5.9 provides a common basis for evaluating the safety, durability and structural performance of storage units used in offices. It defines specific tests, laboratory equipment, conditions of test, and recommends minimum levels to be used in testing. It also defines how performance, durability, and structural adequacy should be evaluated.
