ASSE recognizes the importance and benefits of input from a variety of industry stakeholders in order to develop the best standards and performance documents. Listing Evaluation Criteria (LEC) are Other Recognized Documents (ORD’s) that establish the initial rules for unique products in the marketplace. An LEC is an opportunity for new devices to gain a footing in the marketplace when combined with 3rd-party certification.
An LEC is valid for 5 years from publication date. At that point, the ASSE Product Standards Committee (PSC) will observe its market acceptance and decide the appropriate route for it in partnership with the original requester.
All public comments are reviewed after the end of the 20-day public review period by the PSC and are resolved to the best ability of the PSC and the commenter. Comments must include the following:

|ASSE LEC 2008||Point of Entry Anion Exchange – Nitrate Reduction||07/16/2020||Point of Entry anion exchange water treatment products are intended to be used in residential and commercial applications to reduce nitrate from drinking water.|
|ASSE LEC 2010||Proportional Flow Control Devices, with Protection from Cross Contamination via Hydronic Water, for use in Drinking Water Installations||07/22/2020||
The purpose of the device is to control the flow of potable water based on the pressure of hydronic water from a hydronic system. The device performs this hydraulically and has integral cross contamination protection between the potable and hydronic water. This device is typically installed in conjunction with a heat exchanger and a part of a hydronic system loop.
|ASSE LEC 2002-2017||Shower Filtration Fitting for Reduction of Chloramine||Feb 2017||Devices are shower filters are designed to reduce contaminants typically found in potable water supply lines, such as chlorine and chloramine. The product improves the showering experience by reducing aesthetic contaminants from supply water.|
|ASSE LEC 2004-2019||Drinking Water Treatment Systems Using Air as a Source||July 2019||Atmospheric water generators are intended to be used to produce drinking water. Typical applications include areas where water is scarce or where water supplies are of unknown water quality. Critical components of these systems include a condenser, storage tank, and disinfection control techniques to address microbiological water contamination.|
|ASSE LEC 2006-2019||Point of Entry Reverse Osmosis Systems||Sept 2019||This covers contaminant reduction claims for POE RO systems used to treat drinking water. RO water treatment equipment reduce total dissolved solids, heavy metals, microbes, inorganics, and organic water contaminants. POE ROs are typically installed after the water meter in residences or businesses.|
|ASSE LEC 2004-2019||Backflow Preventer and Automatic Boiler or Chiller Filling Device with Pressure Regulating Management||December 2019 2019||ASSE LEC #2009-2019 was created to set performance evaluation criteria for direct-type boiler and chiller fill valve assemblies with an integral backflow preventer and system pressure regulator used to control the inflow of water into heating and cooling systems to ensure sufficient system pressure. These devices protect the potable water supply against backflow due to backpressure and backsiphonage from high hazard contaminants.|
|ASSE LEC 2010-2020||Proportional Flow Control Devices, with Protection from Cross Contamination via Hydronic Water||April 2020||ASSE LEC 2010 devices control the flow of potable water based on the pressure of hydronic water from a hydronic system. The device performs this hydraulically and has integral cross-contamination protection between the potable and hydronic water. Proportional flow- control devices are typically installed in conjunction with a heat exchanger and a part of a hydronic system loop.|
