The Fenestration and Glazing Industry Alliance (FGIA) has released a new specification for evaluating an operable window with an installed Window Opening Control Device (WOCD).

AAMA 950-25, Specification for Window Opening Control Devices (WOCDs) Installed on Operable Windows, an FGIA document, is now available for purchase in the FGIA online store.

“WOCDs are intended to help support window safety,” said Jason Seals, FGIA Technical Manager, Fenestration Standards and U.S. Industry Affairs, and staff liaison for the FGIA Window Opening Control Device (WOCD) Listing Requirements Work Group. “When properly designed, tested, specified and installed, WOCDs can help prevent or reduce accidental falls through open windows by young children, while allowing the ability to open the window fully as may be needed to exit in the event of an emergency.”

ASTM F2090, Standard Specification for Window Fall Prevention Devices with Emergency Escape (Egress) Release Mechanisms, contains requirements for WOCDs regarding general requirements, performance tests, safety information, labeling requirements and installation instructions. This specification uses existing test methods found in ASTM F2090 to evaluate WOCDs installed on operable windows that have been evaluated to meet the requirements of AAMA/WDMA/CSA 101/I.S.2/A440, North American Fenestration Standard/Specification for windows, doors, and skylights (NAFS).

ASTM F2090 covers other types of window fall prevention devices such as window fall prevention guards and window fall prevention screens, these devices are outside the scope of this specification. This specification evaluates factory-installed WOCDs or those specified by the window manufacturer as a field installed kit.

AAMA 950-25, as well as other documents available from FGIA, may be purchased from the online store at the discounted member rate of $25 or the non-member price of $70.
