A proposed new ASTM International guide—ASTM WK46735, Guide for Evaluating the Variables that Can Increase the Durability of an Installed Flashing Assembly— aims to define ‘durable flashing’ and create a level playing field for flashing manufacturers.
The draft standard will provide measurable and process-based assessment elements to characterize flashing assembly performance, covering the materials’ lifecycle from initial physical properties to potential repairability.
“Manufacturers first, and then building owners, will be the primary people interested in ASTM WK46735,” explained Michael Schmeida (Oatey Co.) “They want to know that what they have or are installing will be durable enough to meet their needs for the roof they own or are working on.”
The draft is being developed by Subcommittee D08.24 on Sustainability, part of ASTM Committee D08 on Roofing and Waterproofing.
