Update to BIFMA X5.9 for Storage Units
The Business Institutional Furniture Manufacturers Association (BIFMA) has released an updated, ANSI approved, version of BIFMA X5.9 – Storage Units. The 2019 version, which supersedes the 2012 edition, was released on February 7, 2019.
SAFEGUARDS | Hardgoods NO. 025/19
BIFMA X5.9 defines specific tests, laboratory equipment, conditions of test, recommended minimum levels to be used in the test, and how to evaluate the performance, durability, and structural adequacy of storage units used in offices.
Among several updates, the standard contains an improved method for testing stability, as well as a scope expansion to include vertical file cabinets; BIFMA will formerly withdraw X5.3-Vertical Files.
