  6. Drinking Water Product Certification

  7. Drinking Water Product Certification • ANSI accredited global certification program • Dedicated team of engineers, chemists and sanitarians all over the world • Active participation at trade shows, joint committees and industry task groups

  8. Drinking Water Product Certification Drinking Water Treatment Units • Drinking water treatment units – aesthetic effects (non health) - NSF/ANSI 42 • Drinking water treatment units – health effects - NSF/ANSI 53 • UV microbiological water treatment systems - NSF/ANSI 55 • R.O drinking water treatment systems – - NSF/ANSI 58 • Residential Water softeners - NSF/ANSI 44

  9. DWTU Certification Process • The steps involved: • Client requests certification • UL provides quote and requests client authorization • Information acquistion • Gather information on company and products, which includes a Wetted Parts List • Plant Audit • A representative from our office staff will visit each manufacturing facility for a preliminary production inspection. Samples are selected at this time.

  10. DWTU Certificaiton Process (contd.) • ProductTesting • Products are tested as per the standard • Results verified to meet standard requirements • Literature Review • All product literature and packaging will be reviewed • Classification • A report is written and upon successful completion, products will be authorized to bear the UL mark. Products will be listed on UL’s website. • Follow-up services • UL field rep will make semi-annual unannounced factory visits to monitor ongoing quality control. Recertification evaluation every 5 years.

  11. DWTU StandardsWhat does being certified mean? • Material Safety • Product does not impart contaminants into the potable water pathway • Extraction testing depends on product’s ingredients • Structural Integrity • Cycle testing to simulate operation of product over a projected lifetime • Hydrostatic testing ensures product design is capable of withstanding intended application

  12. Drinking Water Product Certification Drinking Water System Components • Housings, tubing • Valves & gaskets • Tanks & Coatings • Health Effects -NSF/ANSI Standard 61 Drinking Water Treatment Chemical Additives • Disinfectants/antiscalants/dispersants/coagulants • Health Effects - NSF/ANSI Standard 60

  13. UL’s Water Quality Mark An important credential in your key markets • Demonstrates compliance to all applicable health-effect standards • Fully recognized and accepted by the U.S. EPA as well as AHJ’s in the U.S. & Canada
