UV Degradation and Shelf Life of Corrugated Plastic Tubing for Outdoor Applications
ABSTRACT: The rates of embrittlement of corrugated plastic tubing (CPT) resulting from two accelerated ultraviolet (UV) exposure methods were compared with those from natural sunlight exposure in Ohio. Predictions of CPT storage shelf life were based on the effect of UV light exposure. Fourteen average months of exposure in Ohio, or 5600 MJ/m², is the maximum recommended shelf life for CPT storage. Shelf life tests can be conducted using accelerated exposure to 450 MJ/m² of concentrated sunlight or 800 Weatherometer hours, both followed by a flat plate impact test of 30 J. Protection against UV embrittlement during the recommended shelf life is adequate if all samples exposed on accelerated machines pass the impact test.
