Work Item
ASTM WK74970
New Test Method for Evaluation of the Extent of Oxidation in Polyolefin Piping by Using Infrared Spectroscopy to Determine a Ketone Carbonyl Index.
1. Scope
The development of specifications for plastic pipe, fittings, and appurtenances; practices for joining and installing plastic pipes; test methods; terminology, systems and services specific to plastic piping systems and the stimulation of related research.
The work of the Committee may include the consideration of composite piping systems, and components which are partially plastic.
The work of the Committee will be coordinated with ASTM Committee and other organizations having mutual interests.
Keywords
polyolefin; oxidation; FTIR; ketone carbonyl index
Rationale
Evaluation of polyolefins for oxidation by FTIR spectroscopy is commonly done. However, neither existing methods for specific products, like ASTM F2102, nor a general carbonyl index method under development in Subcommittee D20.70 generate a result that has ever been applied to the impact that such oxidation can have on long term polyolefin pipe performance. This proposed new standard will be based on a method that has been utilized for over 40 years to quantify oxidation in polyolefin piping products that yields a result which decades of research correlates with the impact of such oxidation on performance.
The title and scope are in draft form and are under development within this ASTM Committee.
