POLYETHYLENE RESIN TESTING REQUIREMENTS TO SUPPORT ASTM D2513 UV EXPOSURE LIMITS OF POLYETHYLENE COMPOUND
|Publication Date:||1 August 2013|
The objective of this document is to provide testing requirements for Polyethylene (PE) compounds to support recent modifications to the Outdoor Storage Stability section of ASTM D2513. Specifically, those modifications were to show:
(1) Code C (black with 2 % minimum carbon black) PE pipes with 2.0 to 3.0 weight percent of a well dispersed carbon black would be considered stabilized against deterioration from unprotected exposure to UV for not less than 10 years and,
(2) Code E (colored with UV stabilizer) PE pipes would be considered stabilized against deterioration from unprotected exposure to UV for not less than 3 years.
