Develop a new Standard Specification for Convoluted Backing Rings for Lap-Joint PE flange adapters per ASTM F2880. The new Specification will cover both all-metal backing rings and metal backing rings encapsulated in polypropylene. The specification will refer to convoluted backing rings and will include performance requirements but will not include reference to proprietary or patented requirements or dimensions.
No existing standard covers the existing products. The products are used in PE piping applications currently.
The title and scope are in draft form and are under development within this ASTM Committee.Back to Top
