The Fenestration and Glazing Industry Alliance has updated a specification and test method intended to model, through accelerated testing, the normal wear that can be expected during the life of a typical AW Class window or door. AAMA 910-24 (Life Cycle Specifications and Test Methods for AW Class Windows and Doors), an FGIA document, is now available for purchase in the FGIA online store. The document was last updated in 2016. It was updated by the FGIA Life Cycle Testing Review Task Group.

“Since its introduction more than 20 years ago, the AAMA 910 ‘Life Cycle’ testing specification for AW Class windows and doors, formerly referred to as ‘Architectural Windows,’ has been widely accepted by industry consultants and the specifying community,” said Rich Rinka, FGIA technical manager for fenestration standards and U.S. industry affairs. “With the advance of technology, along with two decades of experience and test data from a variety of materials, this specification and test method has now been updated to reflect the changing needs of the marketplace, such as longer warranty periods, sustainable design, more durable finishes and increasingly more stringent code requirements.”

In addition, descriptive language has been clarified for ease of use, Rinka said.

“In this specification, [there was the] enhancement of performance requirements to include thermal cycling and increase the number of operating cycles, as well as increased misuse loads now helps to more clearly differentiate AW products from other performance classes,” Rinka said.

AAMA 910-24, as well as other documents available from FGIA, may be purchased from the FGIA online store at the discounted member rate of $20 or the non-member price of $60. The North American Fenestration Standard, which references AAMA 910, is also available for purchase.
