This slide presentation outlines information on an AwwaRF project that studied the performance and life expectancy of elastomeric components in contact with potable water. Topics covered include: statement of problem and project overview; elastomer components; laboratory testing program; field testing program; and, identified concerns. Specific topics include: overview of chlorine and chloramines disinfection; impact of chloramines on physical systems; implications for utilities; expected physical and chemical reasons for impacts; laboratory accelerated degradation; field sample degradation performance; performance matching; Neoprene degradation; EPDM peroxide degradation; time-temperature superposition; accelerated testing data; crosslink density; and, field samples.
