  3. Acoustic definitions

  4. Acoustic definitions Airborne through the wall Structure-borne coming from the seal Structure-borne coming from supports Sounds : Airborne + Structure-borne Airborne

  5. European regulations Requirements on wastewater installations • On structure-borne noises (equipment behind the room)

  6. Conclusion

  7. European test method formulated by CEN TC 126 Inlet DN 70 to 150 Support device Wall : 250+50 kg/m² No sealing • New standard EN 14366: 2004 • Acoustic property of products for construction used in buildings. « Laboratory measurements of noise from wastewater installations » CEN TC 126 is a working group representing a cross section of materials (CI, Plastic, etc.)

  8. Test ResultsApplication in Germany EG UG IBP laboratory – Stuttgart (Independent Test) Tested Ensign Cast Iron to the New standard EN 14366 : 2004 Structure-borne noises : DN 100 - 220 kg/m² wall - 4 l/s

  9. Conclusion • Airborne noise Cast iron >6-9dB(A) quieter than Twin-wall PVC Cast iron >10dB(A) quieter than HDPE silent Cast iron >13dB(A) quieter than stainless steel Cast iron >14dB(A) quieter than PVC-U • Airborne and structure-borne noise • Cast iron system using RB422 bracket meets the most stringent requirement of BS8233 • Cast iron system using new separate fitted to ductile bracket EF048 = >6-9dB(A) superior to best plastic material • Tests and Results completed: • Independent testing facility • To the new appropriate standard • Test results certified. • ALL MATERIALS SHOULD TEST TO BS EN 14366
