The Fenestration and Glazing Industry Alliance (FGIA) has updated a specification establishing methods of test cover procedures, materials and performance criteria for determining the durability of gear type rotary and linear operating devices used for opening and closing casement, awning, jalousie, jal-awning and other similar types of windows. , Specification for Rotary and Linear Operations in Window Applications, an FGIA document, is now available for purchase in the FGIA online store. This document was last updated in 2016.

Rotary and linear operators are hardware components used to open and close the operable sash of casement, awning, jalousie, jal-awning and similar type windows. The purpose of this document is to establish a method for characterization of the performance of operators as well as defining the method(s) by which these characteristics are to be tested.

“The multitude of factors that a fenestration product experiences in a real-world application makes prediction of lifespan extremely complex,” said Glenn Ferris, FGIA Technical Standards Specialist. “This is also the case for window components such as rotary and linear operators.”

, as well as other documents available from FGIA, may be purchased from the online store at the discounted member rate of $20 or the non-member price of $60. NAFS, which references AAMA 901, is also available for purchase.
