The Importance Of Product
Service Life As Documented By ETL-Verification. All brands of PVC-coated galvanized rigid conduit comply with standards as established by UL 6. Only some brands of PVC-coated galvanized rigid conduit are authorized to carry the ETL-Verifed PVC-001 label --- the only definitive difference between existing brands. Therefore, if predictability of product service life is important to engineering design, avoidance of costly or catastrophic product or system failure, it should be assumed in the specification process, that only PVC-coated galvanized conduit carrying the ETL-verification label, will meet the standards established by all relevant ASTM tests, including those predicting product service life.
