5、dered to be a section of this standard. It is intended to providebackground information only.ASSE standards are developed in the interest of protecting the health of the public.ASSE recognizes that many floor drains installed within buildings are rarely used. Withoutperiodic use floor drain plumbing
6、-code-required water trap seals will eventually fail due toevaporation. Potentially objectionable and hazardous sewer gases may then escape into thebuilding through the ineffective trap.The model plumbing codes require that floor drain trap seals that are subject to evaporationare be provided with a
7、 method that offsets evaporation. Currently there is one approvedmethod. The method provides a periodic automatic admission of water directly into the floordrain - such as a trap primer.This new ASSE Standard #1072 introduces an alternative method of protecting floor drainwater trap seals - Barrier-
8、Type Floor Drain Trap Seal Devices.In 2003 a request was submitted to ASSE to develop this standard.Because this barrier method does not automatically and periodically provide water to replenishthe trap seal, it must provide a barrier on the inlet side of the trap seal that will minimize itsevaporat
9、ion caused by the ambient air on the building side of the trap. This barrier must alsoprovide adequate drainage capabilities required for the floor drains intended use as deter-mined by its design, size, and installation location.While developing the performance requirements and tests for these devi
10、ces, certain adverseconditions were taken into consideration. These are the introduction of fouling substances suchas dirt/sand, floor wax, or grease directly into the device. In addition drainage requirements toaccommodate infrequent, and unusually sizeable, water flows caused by water line breaks,
11、fixture overflows, or backflow preventer discharges are provided. Tests are included to confirmthat devices submitted for approval provide the performance requirements listed above -among others.Test requirements are also included that evaluate the devices based on size and installationconditions.Th
12、ese removable devices are designed to be installed in either new, or existing, floor drain thatconform s to ANSI/ASME A112.6.3 installations.ForewordBarrier Type Floor Drain Trap Seal Protection Devices iiiASSE Standard #1072 - 2007This standard represents a composite of knowledge and experience of
